Abstract

The herbivorous ladybird beetle Henosepilachna vigintioctopunctata depends primarily on solanaceous plants. The utilisation of a novel fabaceous host, centro (Centrosema molle), by this beetle has been reported from several regions in Southeastern Asia, but details of the distribution and feeding habits of H. vigintioctopunctata populations on centro are largely unknown. Our study aimed to gather basic information on the utilisation of centro by H. vigintioctopunctata in the Nusa Tenggara region of southeastern Indonesia. Field surveys indicated that H. vigintioctopunctata did not yet utilize centro in the wild in this region. However, in feeding-choice experiments in the laboratory, all beetle populations tested from this region had some potential to utilize centro, i.e., showed some feeding acceptance of this plant. Based on these results, we discuss the current status of the Nusa Tenggara H. vigintioctopunctata populations in using centro as a host.

Abstract

Epilaehna sp. aff. emarginata had been considered as a specialist on Mikania micrantha (Compositae). However, recently its oceurrence on Leucas lavandulifolia (Labiatae) was reported. Preliminary field observations of some beetle populations showed that they had different on the host plant utilizations. However, the result was not sufficient to interpret the food preference of the beetles. These experiments weremade in order to clarify those previous observations.Experiments on adult food preference was investigated under uncontrolled room conditions.Four beetle populations (Bogor, Cibinong, Klaten and Malang) were subjected to choice tests offering Mikania micrantha (Compositae) and Leucas lavandulifolia. These experiments indicated that individual beetle has similar trend on food preference within each population. Bogor and Cibinong populations preferred to feed on both M. micrantha and L. lavandulifolia while. Klaten and Malang populations preferred exclusively on L. lavandulifolia. The populations showed different food preferences on the different geographical conditions of Java.
