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.

Abstract

Study on fluctuation of rainfall and insect community was conducted in a tropical forest, Gunung Halimun National Park. Ten years rainfall data was available to discuss their fluctuations. Rainfall was relatively non-seasonal with high number of almost entire monthly rainfalls.Although fluctuation of rainfall in GHNP did not show clear seasonal trend, however appearance of less rainfall showed from June to September. There were several slight fluctuations in the number of rainfalls from a month to another and some time showed major and minor peaks. Monthly dry months had never reached 0 mm. In ordinary years, only one-month drought occurred in July 1991 (90 mm) and December 2000 (8 mm). Strong drought occurred only during El Nino of 1994 and 1997, which have 3 to 4 dry months. Fluctuation of insect community was studied from March 2000 up to February 2001. Two insect collection methods were applied by setting up light traps and pitfall traps. Total individual of each order of insect counted monthly and to be compared one to another. Changing the number of monthly individual of each order was interpreted to the number of monthly rainfall in order to analyze the relation of changing of the number of rainfall and the individual of each order of the insect collected. Fluctuation of the number of monthly rainfall was synchronous to the number of insect community collected by light traps (night flying insect) but tend to opposite to the number of insect collected by pitfall traps (ground insect).
