Laboratory experiment was conducted to compare the relative toxicity of biopesticides like Pseudomonas fluorescens strain pf1 and neem oil with imidacloprid, quinalphos, and endosulfan against an egg parasitoid, Trichogramma chilonis, and a predatory green lacewing, Chrysoperla carnea. Biopesticides were safer than chemical insecticides in minimizing harmful effects on development and behavior of two natural enemies. P. fluorescens treatment recorded high parasitism (≈73%) and parasitoid egg development (≈72%) of T. chilonis. It also gave high egg (≈75%) development on C. carnea. Neem oil recorded 58.9 % parasitoid emecrgence, and 59.3 % parasitism, and 63.1 % egg hathability. Other chemical insecticides exhibited high damages on the natural enemies.

Mealybugs (Hemiptera: Coccomorpha: Pseudococcidae) harbor diverse microbial symbionts that play essential roles in host physiology, ecology, and evolution. In this study we aimed to reveal microbial communities associated with two different mealybugs, papaya mealybug (Paracoccus marginatus) and two-tailed mealybug (Ferrisia virgata) collected from the same host plant. Comparative analysis of microbial communities associated with these mealybugs revealed differences that appear to stem from phylogenetic associations and different nutritional requirements. This first report on both bacterial and fungal communities associated with these mealybugs provides a preliminary insight on factors affecting the endomicrobial communities.
