Detection of genetic polymorphism in the populations of brinjal shoot and fruit borer, Leucinodes orbonalis (Guenee).
In the present study six different populations of L. orbonalis were collected and subjected to analysis of genetic variability in terms of carboxylesterase isozyme pattern and DNA polymorphism using RAPD-PCR. Pattern of carboxylesterase revealed a similar isozyme cluster in the populations namely, sivaganga (population-3), dindigal (population-4), virudhunagar (population-5) and coimbatore (pop...

In the present study, bioefficacy of spinosad (56.25, 72 and 90 g a.i. ha -1 ) and emamectin benzoate (5, 6.25 and 12.5 g a.i.ha -1 ) was studied in comparison to cypermethrin (50 g a.i. ha -1 ) and selfformulated neem seed extract (5 %). Field experiments were undertaken for two cropping seasons during kharif 2005 and summer 2006. From the study it was found that spinosad afforded moderate con...

متن کاملEcosmart Biorational Insecticides: Alternative Insect Control Strategies
Pest insects can damage agricultural crops, consume and/or damage harvested food, or transmit diseases to humans and animals. The past 30 years has witnessed a dramatic reemergence of epidemic vector-borne diseases throughout much of the world (Atkinson, 2010). Prior to the development and commercial success of synthetic insecticides in the mid1930s to 1950s, botanical insecticides were the for...

field experiment was conducted to determine the economic threshold for spraying of flubendiamide against the brinjal shoot and fruit borer. flubendiamide was applied based on 10 thresholds including 2% shoot infestation, 5% shoot infestation, first fruit set + 2% fruit infestation, first fruit set + 5% fruit infestation, 2% fruit infestation, 5% fruit infestation, 2% shoot + 2% fruit infestatio...
