Entomopathogenic Microorganisms in Pest Control

To compare the cerambycid fauna (Coleoptera) in different kinds of forests in Nara Prefecture, central Japan, we captured adult beetles by using 2 types of barrier traps from April to October 1992. Six forests were used: 2 laurel forests, a deciduous broad-leaved forest, a cedar and cypress forest, a red pine forest, and a beech forest. One trap type was baited with benzyl acetate, which emits an odor resembling that of flowers; and the other trap type was baited with α-pinene and ethyl alcohol, which emits an odor that stimulates the oviposition of the beetles. A total of 10,840 individuals belonging to 63 species (≈9% of all Japanese species) was collected during the course of the study. The greatest number of beetle species were captured in the beech forest where tree species were the most diverse, and the fewest were trapped in laurel forest. The greatest number of beetle individuals were captured in the cedar and cypress forest and the fewest were trapped in the pine forest. The beech forest had a different beetle fauna and higher diversity than other forests. In the laurel forests and in the cedar and cypress forest, diversity of beetles was relatively lower, reflecting poor tree species richness. The number of beetle species tended to increase in proportion to the number of tree species.
