Abstract

Adaptive responses of an herbivorous ladybird beetle Henosepilachna vigintioctopunctata (Epilachninae) and the host plants to dry season were studied in Pasuruan and Malang, East Java. Nineteen species of host plants of the beetle have been recorded in Java, however only fiveteen species are found as preferred host plants of the beetles in Pasuruan and Malang. During the season beetles tend to prefer the plants of Datura metel, Brugmansia spp., Solanum melongena, S. torvum, S. pseudocapsicum, and 5. nigrum as their hosts and this might course strong damage to the plants.It is obvious that the beetles tend to move to the humid places to find more suitable food. It is also found that during the days of drought, the beetles feed on eggplant fruits by tunnelling into the flash of the fruits.Some of the beetles ovaries would not develop in the drought and a part of them might enter the diapause stage.Other responses of the beetles to drought will be discussed in the paper.

Abstract

Ladybird beetle, Henosepilachna vigintioctopunctata Fabricius (Coleoptera: Cocinellidae) has a wide host plants belonging to family of Solanaceae. The species can be a serious pests of solanaceous crops, such as, eggplants and potatoes. The aims of the research were to study life table and to measure demography parameters of H. vigintioctopunctata fed by leaves of Solanum torvum, S. nigrum, S. melongena, and Brugmansia suaveolens. Results showed that the highest longevity (68.7 days, male and 79 days, female) occurred in H. vigintioctopunctata fed by leaves of  S. nigrum, followed by S. torvum (20.6 days, male and 31.7 days, female), S. melongena (1.5 days, male and 2.5,0 days, female, and B. suaveolens (1.8 days, male and 1.7 days, female). Based on demography parameters, the highest net reproductive rate occured in H. vigintioctopunctata fed on leaves of S. torvum (R0 = 2.11 individu), followed by S. nigrum (R0 = 0.64 females/female), S. melongena (R0 = 0.06 females/female), and B. suaveolens (R0 = 0.006 females/female). Generation time was high in H. vigintioctopunctata fed by S. nigrum (28.53 days) and S. torvum (27.42 days) compared to S. melongena (5,9 days) and B. suaveolens (2.5 days). Intrinsic growth rate of H. vigintioctopunctata was highest in S. torvum (r = 0.0094 females/female/day). Based on the life table and demography parameters, S. torvum is the most suitable plant for growth and development of H. vigintioctopunctata.
