Effects of Pyriproxyfen on Female Reproduction in the Common Cutworm, Spodoptera litura (F.) (Lepidoptera: Noctuidae)
The common cutworm, Spodoptera litura, is a rapidly reproducing pest of numerous agricultural ecosystems worldwide. The use of pesticides remains the primary means for controlling S. litura, despite their negative ecological impact and potential threat to human health. The use of exogenous hormone analogs may represent an alternative to insecticides. Juvenile hormones (JHs) play an important ro...
متن کاملCold hardiness of Helicoverpa zea (Lepidoptera: Noctuidae) pupae.
An insect's cold hardiness affects its potential to overwinter and outbreak in different geographic regions. In this study, we characterized the response of Helicoverpa zea (Boddie) pupae to low temperatures by using controlled laboratory measurements of supercooling point (SCP), lower lethal temperature (LT(50)), and lower lethal time (LLTime). The impact of diapause, acclimation, and sex on t...
متن کاملDevelopment and emergence patterns of the tobacco cutworm Spodoptera litura (Lepidoptera: Noctuidae)
Study of lifecycle patterns and rhythms is important to understand the ecology and evolution of insects. The tobacco cutworm Spodoptera litura (Lepidoptera: Noctuidae), is a serious polyphagous pest in Asia, Oceania and the Indian subcontinent. The laboratory investigations of development patterns and circadian rhythms described in this paper have shown that the development duration from egg to...
متن کاملTemperature- and CO 2 -Dependent Life Table Parameters of Spodoptera litura (Noctuidae: Lepidoptera) on Sunflower and Prediction of Pest Scenarios
Predicted increase in temperature and atmospheric CO2 concentration will influence the growth of crop plants and phytophagous insects. The present study, conducted at the Central Research Institute for Dryland Agriculture, Hyderabad, India, aimed at (1) construction of life tables at six constant temperatures viz., 20, 25, 27, 30, 33, and 35 ± 0.5 °C for Spodoptera litura (Fabricius) (Noctuidae...
متن کاملResponses of the cutworm Spodoptera litura (Lepidoptera: Noctuidae) to two Bt corn hybrids expressing Cry1Ab
To examine the responses of the secondary lepidopteran pest Spodoptera litura to two Bacillus thuringiensis (Bt) corn hybrids [5422Bt1 (Event Bt11), 5422CBCL (MON810)] expressing Cry1Ab, larval bioassays with Cry1Ab toxin, corn leaves or kernels and bagging on corn plants were conducted. The results showed that larvae displayed a similar performance when fed kernels, but not leaves of 5422Bt1, ...
