Abstract

Faunistic, ecological, biogeographical and phylogenetic aspects of Coleoptera as gall-inducers and associates in plant galls in the Orient and eastern Palearctic.

Abstract

This paper attempts to clarify the faunistics of coleopteran gall-inducers, interactions of Coleoptera with other gall-inducing arthropods, and examples of these in the Indian subcontinent. Their usefulness in terms of biological control, as well as their phylogeny and evolution, are discussed. This paper concentrates on select species from the Orient and eastern Palaearctic regions. The cotton stem weevil Pempherulus affinis, amaranthus stem weevil Alcidodes bubo, lissora-fruit weevil Baris cordiae and tamarix gall weevil Nanophyes sp. are some examples of gall inducers abundant in the Orient. Interactions of coleopterans with plant galls for biological control have been discussed, using the following examples: Conotrachelus albocinereus, Acythopeus burkhartorum and Smicronyx albovariegatus. These examples have been considered mainly because plants like Coccinia grandis and Parthenium hysterophorus, and parasites like Striga sp. are proliferating in the Orient and Palearctic regions.
