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 کاملComparison of Amino Acid Sequences of Halloween Genes in Spodoptera litura and Spodoptera littoralis
20-Hydroxyecdyone (20E), an active form of ecdysteroid, is the key hormone in insect growth and development. To date five P450 enzymes involved in the last four steps of ecdysteroid biosynthesis from ketodiol to 20E namely Spook (Spo), Phantom (Phm), Disembodied (Dib), Shadow (Sad) and Shade (Shd) related to ecdysteroid biosynthesis, are identified and the character of last four enzymes is well...

متن کاملInsecticidal Potentiality of Flavonoids from Cell Suspension Culture of Marchantia Linearis Lehm. & Lindenb against Spodoptera Litura F
Bryophytes were diverse, primitive non vascular amphibious taxa distributed worldwide and form the second largest category of plants. Bryophytes synthesize an array of phytochemicals to combat against the unhospitable environmental conditions including predation, UV radiation, high temperature and pest and pathogens. The present investigation was undertaken to elucidate flavonoids from in vitro...
متن کاملSpodoptera litura nuclear polyhedrosis virus (NPV-S) as a component in Integrated Pest Management (IPM) of Spodoptera litura (Fab.) on cabbage
Field tests were conducted to evaluate the effect of Spodoptera litura (Fab.) nuclear polyhedrosis virus (NPVS) alone and in combination with endosulfan and neemarin (neem seed kernel extract) against S. litura in cabbage. Treatment with NPV-S (500 LE/ha) + Endosulfan (625 ml/ha) was better in reducing the larval population and increasing yield than other treatments. However, considering cost b...
