Abstract

Semiochemical footprints of the predaceous coccinellid beetle, Menochilus sexmaculatus, deter Zygogramma bicolorata (Coleoptera: Chrysomelidae) from feeding on Parthenium.

Abstract

Present study assessed if semiochemical cues left by an aphidophagous beetle, M. sexmaculatus influenced foraging behaviour of a phytophagous beetle, Z. bicolorata on noxious weed, P. hysterophorus. The lower predation attributes of Z. bicolorata in presence of M. sexmaculatus semiochemical footprints confirms they interfere with weed biological control.
