The European corn borer (ECB; Ostrinia nubilalis ) is an economically damaging insect pest of maize ( Zea mays L.), important cereal crop widely grown globally. Among inbred lines, the genotype Mp708 has shown resistance to diverse herbivorous insects, although several aspects defense mechanisms plants are yet be explored. Here, changes in root physiology arising from short-term feeding by ECB ...

We aimed to monitor the species diversity and dynamics of number soybean pests using light traps with an original design develop protection systems against main phytophages. Traps lured 44 insects from eight orders 27 families. The capture 15 economically important phytophages was recorded—representatives various families: order Lepidoptera—Noctuidae, Crambidae, Erebidae, Geometridae; Hemiptera...

Insect-protected corn hybrids containing Cry insecticidal proteins derived from Bacillus thuringiensis have protection from target pests and provide effective management of insect resistance. MON 89034 hybrids have been developed that produce both the Cry1A.105 and Cry2Ab2 proteins, which provide two independent modes of insecticidal action against the European corn borer ( Ostrinia nubilalis )...

Genetically modified corn crops have been developed to reduce the impact of potentially devastating agricultural pests such as the European Corn Borer (Ostrinia nubilalis). Continuous exposure to Bt toxins in genetically modified corn results in the increased prevalence of European Corn Borers that are resistant to these toxins. In this article, we first analyze the evolution of resistance in a...

Strategies proposed for delaying resistance to Bacillus thuringiensis toxins expressed by transgenic maize require intense gene flow between individuals that grew on transgenic and on normal (referred to as refuges) plants. To investigate gene flow in the European corn borer, Ostrinia nubilalis (Hübner), the genetic variability at 29 sampled sites from France was studied by comparing allozyme f...

The black cutworm, Agrotis ipsilon (Hufnagel) (Lepidoptera: Noctuidae), is a serious localized pest of vegetable and field crops. We have characterized a newly discovered baculovirus, the Agrotis ipsilon multicapsid nucleopolyhedrovirus (AgipMNPV), that was isolated from A. ipsilon in Illinois. Restriction enzyme fragment profiles of AgipMNPV DNA were distinct from those of previously described...

In the article, 10 species of pests that damage rice plants during season in agrobiocenosis were identified. Leptestheria dahalacensis Sars, Apus concriformis Sh., Corn stalk Ostrinia nubilalis Hb , and Cephus pygmaeus have been reported to cause grasses.A growth calendar has developed. pest experiment germination period, biological effectiveness drug was highest for 15 days, accounted 93.9%, v...

The European Corn Borer (ECB), Ostrinia nubilalis, is an agricultural pest which bores small holes in the rind of maize stalks and then proceeds to consume pith. Because most damage stalk internal, it difficult quantify individual without time-consuming, manual examination. This work focused on determining feasibility detecting internal using non-destructive, electrical measurements. Laboratory...
