Native predators and parasitoids were identified against the invasive whiteflies in cotton ecosystem. Over past several decades, its control has been increasingly based on use of natural enemies. The enemies include Cheilomenes sexmaculata, Chrysoperla carnea, Diadiplosis sp, Orius insidiosus, two coleopteran beetles, Cybocephalus nipponicus, Delphastus catalinae species Aphelinidae parasitoids...

Studies were conducted on the incidence, intensity of infestation, infestation grade index and natural enemy complex rugose spiralling whitefly (RSW) Aleurodicus rugioperculatus Martin infesting coconut palms so as to evolve ecofriendly IPM. RSW incidence was at peak in June 2018 (38.3%), subsequently declined December (20.5%), but later attained again March 2019 (47.5%). The pest also showed i...

Two natural enemy species are frequently released simultaneously to control one pest species in augmentative biological control in greenhouses. Intraguild predation (IGP) and interspecific competition between natural enemies might affect the biological control. IGP occurs between two parasitoids, between one parasitoid and one predator, and between two predators. Although unidirectional IGP has...

The present study investigated the biology and morphometric analysis of rugose spiralling whitefly (RSW), Aleyrodicus rugioperculatus on coconut under mini net house condition at Department Agricultural Entomology, Tamil Nadu University-Coimbatore during 2019-2020. was studied by clip cage method morphometrics were done using Leica image analyser. Total lifecycle spiraling 56.23 ± 2.20 days. De...

Bemisia tabaci biotype B has become a major pest, causing serious losses to many agricultural crops worldwide. Chrysopa pallens is an important polyphagous predator of B. tabaci on different agricultural crops. In the present study, prey consumption by C. pallens was determined with feeding on un-parasitized and Encarsia formosa parasitized B. tabaci biotype B prey on tomato host plant at contr...
