Abstract
Population fluctuation of the hard black beetle Pentodon bispino­sus was studied in the adult and larval stages during the period 1988­1990. Ultra violet traps were used to catch the adults. The adult popula­tion increased gradually to reach its peak during July 1989 then de­creased to reach its minimum during January 1990. The population started to increase again to reach its peak during July 1990. As for the larvae, there was only one peak annually that existed during July. Chemical control against white grubs using certain insecticides showed that Furadan 10% added to the soil in shallow furrows at the rate of 63 Kg/f was the most effective compound among the tested in­secticides.
