Long-range migrations of many wind-borne noctuid moths will have been influenced by the expansion of agriculture that provides greater availability of food plants along the migratory route. The migratory, agricultural pest, Trichoplusia ni (cabbage looper) over-winters in southern California and each summer migrates as far north as British Columbia. We explored the degree of genetic connectivit...

Bacillus thuringiensis toxins act by binding to specific target sites in the insect midgut epithelial membrane. The best-known mechanism of resistance to B. thuringiensis toxins is reduced binding to target sites. Because alteration of a binding site shared by several toxins may cause resistance to all of them, knowledge of which toxins share binding sites is useful for predicting cross-resista...

Biodiversity is a function of the number any taxon present, evenness with which taxons are distributed (species or family evenness) and interaction component richness evenness. The present investigation was carried out to study arthropod biodiversity in Horticulture ecosystem at RVS Agricultural College, Thanjavur, India. farm lies between 10.6796° N latitude 78.9194° E longitude an altitude 42...

We created a deterministic, frequency-based model of the evolution of resistance by corn earworm, Helicoverpa zea (Boddie) (Lepidoptera: Noctuidae), to insecticidal traits expressed in crops planted in the heterogeneous landscapes of the southern United States. The model accounts for four generations of selection by insecticidal traits each year. We used the model results to investigate the inf...

Susceptibility to the Cry1Ac toxin from Bacillus thuringiensis in tobacco budworm, Heliothis virescens (F.) (Lepidoptera: Noctuidae), is usually measured by performing bioassays under laboratory conditions. Accurate comparison of Cry1Ac susceptibility among H. virescens samples conducted in different places is challenged by several important methodological aspects, especially if different insec...

The host acceptance of neonate Alabama argillacea (Hübner) (Lepidoptera: Noctuidae) larvae to Bt cotton plants exerts a strong influence on the potential risk that this pest will develop resistance to Bt cotton. This will also determine the efficiency of management strategies to prevent its resistance such as the "refuge-in-the-bag" strategy. In this study, we assessed the acceptance of neonate...

during 2005, in a faunistic survey of tachinidae associated with pests of field crops which carried out in shirvan region (north khorasan province), 3 adult tachinids emerged from agrotis sp. (lepidoptera: noctuidae) larvae collected in sugar beet field of agricultural college of shirvan. the specimens were identified as gonia ornata meigen 1826. this is the first record of the occurrence of th...

The Southern armyworm Spodoptera eridania (Stoll) (Lepidoptera: Noctuidae) is a polyphagous defoliator having wide host range including Soybean. They are one of the important defoliators in tropical and subtropical regions hemisphere. However, this pest reported for first time from Kolhapur, Maharashtra, India on Soybean [Glycine max (L.) Merill].
