Based on the recent revised generic classification of the tribe Epilachnini (Szawaryn et al. 2015), all 27 genera are re-described, diagnosed, illustrated, and included in an identification key. The following nomenclatural changes are made: Epilachna (Hypsa) Mulsant 1850, Epilachna (Cleta) Mulsant 1850, Solanophila Weise 1898, Epilachna (Aparodentata) Wang and Cao 1993, and Epilachna (Uniparode...

An experiment was carried out to study the effect of temperature on biology, oviposition and feeding behaviour as well as host preference of Epilachna beetle, Epilachna dodecastigma (Wied.) on eight varieties of brinjal, Solanum melongena Linn. from November, 2009 to June, 2010 maintaining controlled temperatures of 15oC, 25oC and 30oC using an incubator in the Department of Entomology, BAU, My...

The biosynthesis of the azamacrolide epilachnene by the coccinellid beetle Epilachna varivestis has been studied with 2H-labeled oleic acid, 2H-labeled L-serine, and 13C,15N-labeled L-serine. The incorporation of these precursors into epilachnene defines the origin of the alkaloid's entire carbon/nitrogen skeleton. GC/MS and GC/IR studies of alkaloid produced by Epilachna fed with deuteriated o...

The efficacy of neem oil on the mortality, growth and feeding responses of epilachna beetle showed that all the larval instars were susceptible to this oil. The LC50 values were higher at 3 instar and it was lowest on 1 instar. The LT50 values of oil increases proportionately with increasing larval age and with decreasing oil concentration. Neem oil significantly prolonged larval and pupal peri...
