Spotted wing drosophila
Posted on: October 15, 2013 by Stuart Reitz
Spotted wing Drosophila has been detected in Malheur County. Larvae were found infesting raspberries collected from a homeowner’s garden in Ontario. Spotted wing drosophila (SWD), Drosophila suzukii, is an invasive insect pest of economically valuable small fruit and tree fruit crops that was first identified in the Western United States in late 2008. Spotted wing drosophila has previously been confirmed in 2012 and 2013 in neighboring counties in Idaho (Canyon and Payette) so the discovery in Malheur County is not unexpected. In those Idaho counties, it has been found infesting raspberries, grapes and peaches.
Spotted wing drosophila differs from the common drosophila species such as Drosophila melanogaster that occur in Pacific Northwest fruit crops in that it can attack healthy, undamaged ripening fruit; the common species will only attack overripe, damaged, or dropped fruit. Drosophila larvae in sound ripening fruit are likely to be spotted wing drosophila. Spotted wing drosophila have the potential to be a very serious pest of tree and small fruits. Commercial fruit producers and home gardeners should take all appropriate management efforts for this pest, including:
Monitoring: check fruit regularly for ripeness, damage and presence of SWD. Commercial or home traps are useful for monitoring for SWD adults, and may be useful for control.
Sanitation: remove and destroy infested and overripe or damage fruit
Early harvest: harvest as early as possible to reduce exposure to SWD
Netting: while not practical for large commercial operations, netting may be useful small fruits, and small or single trees or tree branches.
Pesticides: This pest is new and limited information is available on pesticides for control of SWD, but sprays must be timed to kill adults before they lay eggs in fruit.
Please see the following websites for information on identification, biology, monitoring and management of spotted wing drosophila for additional and specific information. Because of the relatively recent nature of this introduction, the provided information is subject to change as we learn more about the biology of this pest.

Scouting for Armyworms in South East Idaho

true armyworm

Scouting for armyworms in South East Idaho
University of Idaho. Pest alert, October 2nd, 2013.
Dr. Arash Rashed, Insect Ecology and Entomology
Dr. Juliet M. Marshall, Cereal Agronomy and Pathology
Very high densities of true armyworms Pseudaletia unipuncta Haworth (Lepidoptera: Noctuidae) were observed in areas of South Eastern Idaho. The armyworm presence was confirmed in at least three fields in Pleasant Valley, following reports of unusual and severe defoliation of volunteer plants in harvested spring wheat (Figure 1). Here is provided some information on identifying armyworms, their lifecycle, and control measures.
What they look like? At this time of year (mid-late September) they could be found in their larval and pupal stages. Like other moth larvae and caterpillars, armyworms possess three pairs of true legs located closer to the head, on the first three segments of the body. There are a series of fleshy legs, or so-called prolegs, on the abdominal (4 pairs) and anal (1 pair) segments. Late instar larvae are approximately 1.5 inches long. Although their body color may vary, a series of orange, black, and brown stripes that run longitudinally along the side of their body is characteristic (Figure 2a). The head is relatively large and brown in color. A closer look at the head would reveal a brownish net-shaped pattern (Figure 2b). The face is characterized with an inverted Y, pale in color (Figure 2b).
Pupae are a shiny red-brown and about an inch long. They can be found just under the soil surface as the last instar (6th) larvae burrow underneath the surface to form a cell and pupate (Figure 3).
Adults are [relatively] heavy bodied moths with a wingspan of about 1.5 inches. Moths are characterized with brownish forewings each with a small white spot in the center. Hind wings are mostly light tan to gray in color.
What is their life cycle? Armyworms are not expected to survive harsh winters of the northern states. Adult moths migrate from southern states and arrive sometime in spring (late April-May). Females lay hundreds of small white-ish eggs in clusters on lower leaves of grasses; eggs would hatch within a week or two. Larvae continue to feed on plant tissue for 3-4 weeks. The last instar larvae inflict the greatest damage. They are mostly active during the night and hide in plant debris and soil cracks during the day. We recommend scouting fields starting in late May, at least every two weeks, until harvest (also see ‘how to control’).
Infestations may start in natural grassy vegetation outside fields and/or nearby pastures, where they later move into crops such as corn and small grains (e.gs. wheat, barley, oat, etc.). Damage is primarily through defoliation but in small grains larvae also feed on flag leaves, flowers, and kernels. True armyworms have a strong preference to feed on grasses. However, if starved, they may start consuming hosts such as legumes (alfalfa, beans, etc.) and several other vegetables.
There can be more than one generation in a growing season; the number of generations depends on the environmental conditions. One generation can be completed in about 6-8 weeks, if environmental conditions are suitable.
How to control? Natural enemies often keep numbers low, and thus, outbreaks of armyworms are not common. Armyworms are preyed upon by predatory beetles and are also susceptible to parasitoids and pathogens. Therefore, high densities of armyworm populations are likely to crash on their own. On occasions, however, insecticidal treatments may be needed.
As larvae are exposed while feeding, foliar insecticides can be effective. The presence of 5 worms (and more) per square foot in a small-grain field at planting or early developmental stages requires treatment. Spraying very early in the morning is the most effective since larvae are active in dark and hide during the day. Since infestations are likely to be patchy, insecticide applications could be limited to specific area(s) within a field. In such case, make sure to also cover a good 40 feet-wide border to prevent armyworms from crawling into adjacent non-infested areas and fields.
Armyworms are relatively easy to control chemically, if pesticides are applied in the right time frame of their developmental stages. Most of the time, when the damage is spotted, it is already too late. This is because feeding by the large last-instar larva causes the most significant damage; at this point insecticidal applications would not be economically justified. Thus, effective monitoring is key to a targeted, timely, and subsequently, successful control.
Scout field margins frequently (every two weeks) for larvae presence and signs of defoliation. Disturbing the soil surface would also help to find pupae and larvae. Moth populations can be monitored with light and/or pheromone traps.
As with several other pests and pathogens, controlling grassy weeds and volunteers within and around field edges would help to eliminate food sources post-harvest. In addition, tillage would help to reduce armyworm populations prior to planting winter crops.
At this time of the year, in southeast Idaho, damaged volunteers could be used to spot the presence of high armyworm populations. If leaf damage is observed, search leaf debris and soil for curled up larvae; tillage in combination with sub-freezing winter temperatures are expected to dramatically reduce the remaining larvae and pupae.

potato psyllids and ZC
Posted on: September 27, 2013 by Erik Wenninger
Nearly all of the fields in the U-Idaho potato psyllid monitoring program have undergone vine kill. Of the sites still being monitored, psyllid numbers are for the most part similar to counts from recent weeks. On a few sites we recorded psyllids for the first time this year. We are still waiting on some Lso testing results, but so far no new psyllids have tested positive for Lso, the bacterium that causes ZC. A few vine-killed / harvested sites in the Magic and Treasure Valleys that tended to have had the most psyllids will continue to be monitored for a few more weeks. In addition, suspected overwintering sites will be monitored during the off-season.

Spotted Wing Drosophila Southwest Idaho update
Spotted wing drosophila (SWD), Drosophila suzukii, is an invasive insect pest of economically valuable small fruit and tree fruit crops that was first identified in the Western United States in late 2008. Since July 2009, it has been found in Florida, Oregon and Washington and now appears to be established in many Pacific Northwest fruit crops. Spotted wing drosophila was confirmed in samples from Nez Pierce, Latah and Canyon Counties., ID in August of 2012, and in June of 2013 SWD adults were collected by a crop consultant from traps in an orchard near Fruitland, ID. The presence of the flies in samples this early in the 2013 season indicates the flies may have overwintered in southwest Idaho in 2012.
We have continued to find SWD throughout the summer in traps placed in the vicinity of southwest Idaho tree fruit and berry crops. Numbers of SWD in traps have increased dramatically over the last fdrew weeks and we have reared SWD adults from larvae found in raspberries, grapes and peaches. Spotted wing drosophila is a temperate vinegar or pomace fly native to Southeast Asia preferring temperatures of 20-30 °C (68-86 °F). The cool, wet weather we are now experiencing is ideal for SWD, and in combination with the presence of ripe, damaged and rotting fruit is likely contributing to the observed increase in the SWD population in southwest Idaho.
Spotted wing drosophila differs from the common drosophila species such as Drosophila melanogaster that occur in Pacific Northwest fruit crops in that it can attack healthy, undamaged ripening fruit; the common species will only attack overripe, damaged, or dropped fruit. Drosophila larvae in sound ripening fruit are likely to be spotted wing drosophila. Spotted wing drosophila have the potential to be a very serious pest of tree and small fruits. Commercial fruit producers and home gardeners should take all appropriate management efforts for this pest, including:

Planting Tips for Winter Cereals - BYDV
Small Grains All Locations
BYDV and aphids
Posted on: September 12, 2013 by Juliet Marshall
Planting winter cereals in Idaho– protecting your investment.
University of Idaho. Pest alert, September 12, 2013.
Dr. Juliet M. Marshall, Cereal Agronomy and Pathology
Dr. Arash Rashed, Entomology
Over the past several years our winter cereal production, in Idaho, has been negatively impacted with various arthropod pests and disease, including Barley Yellow Dwarf Virus (BYDV).
Below, are a few suggestions made to improve the overall health of our winter crops and to reduce the risk of significant yield loss due to disease problems:
Control volunteers and eliminate “green bridges”. Volunteer wheat and barley, as well as wild grasses, can host various pests of small grains, which may later invade your newly emerged winter crop. Break the green bridge by removing volunteers and having at least two weeks where there is no available host material. Corn is also a host for some insects and diseases that will affect cereals. For instance, aphids can transmit BYD virus from corn, which can harbor the virus but not be affected by it. Some evidence suggests that insecticide sprays in corn and in grassy borders would be effective in reducing BYDV incidence.
Small grains and other grasses (including grassy weeds) are known to host various cereal aphids (i.e. bird cherry-oat aphid, corn leaf aphid, and English grain aphid), and in the case of BYDV, the virus itself. Thus, crops like beets and alfalfa are not expected to act as a source of BYDV. If BYD virus was in your barley planted near beets last year, you likely had volunteers and grassy field borders as the source of infection. Fields could also be infected by newly arriving virus-carrying aphids.
Use treated seed. Insecticidal seed treatments can reduce aphid colonization of the crop, and subsequently, the secondary spread of BYDV. However, you may still get some virus transmission until the aphids ingest lethal levels of insecticides. Insecticides will also reduce the impact of wireworm feeding. Fungicides are also important for reducing soil and seed-borne diseases and early infection of seedling diseases.
Use resistant varieties. The most effective means to reduce diseases (stripe rust, for example) is to select varieties with resistance. For some diseases, such as BYDV, we don’t have wheat varieties with known levels of resistance to recommend at this point.
Planting date. Follow recommended planting dates for winter wheat and barley, and avoid early planting to minimize the exposure of emerging plants and young seedlings to virus-carrying aphids and other pests.
Seeding depth. In our dryland areas, we have had enough rainfall to replenish soil moisture in the seeding zone. With adequate moisture for rapid germination, you should not be planting deep – this year plant shallow – 1 to 1.5 inches will promote rapid emergence, good stand establishment and will help plants to withstand soilborne diseases such as Fusarium dryland crown rot. Deep planting will force the seed to expend more energy getting to the soil surface, weakening the seedling. It will also increase the chances of crusting prior to emergence. Under irrigation, the same practices apply – with adequate moisture, never plant deeper than 1.5 inches.
Seeding rate should be calculated based on seeds per acre, not lbs/A. Seed irrigated crops at 1 to 1.2 million seeds per acre when planting in our recommended planting window, as winter cereals will tiller adequately. Obviously, if you have to seed later following potatoes or sugar beets, there is less time for plant development and you should increase your seeding rate. If you have a very rough seed bed, increasing the seeding rate will also improve uniform plant stands. Under dryland conditions, reduce the seeding rate significantly, to 600,000 seeds/A for winter barley and 700,000 seeds/A for winter wheat.
Feed the seed. Use phosphorus to promote good root development. Starter fertilizers go a long way to promoting healthy crops, even when soil tests indicate adequate phosphorus levels. At high soil pH, phosphorus becomes unavailable, so even 10-15 lbs in furrow or below the seed can make considerable differences in root development and plant health.
Feed the plant. Soil test to determine available nutrients. Fertilize for expected yield. Consider adding 10-20 lbs/A KCl for straw strength and disease reduction. Sulfur is very important for end-use quality, and 20-40 lbs of sulfate per acre is strongly recommended for protein quality of hard red and hard white winter wheat.
Scout for problems. Monitor crops as they are growing for symptoms of nutrient deficiencies, weed infestations, insect problems, and disease incidence, and treat according to recommendations. The faster your remedy yield-robbing maladies, the greater your yield potential.
As a general rule, agronomic and cultural methods must be practiced, not only to reduce immediate risk, but also to help to achieve a sustainable pest management in the long run.
