Respon fungsional parasitoid Cephalomonia Stephanoderis betr terhadap bubuk buah kopi, hypothenemus hampei ferr=functional response of parasitioid chephalomomia Stephanoderis betr. to coffee Berry Borer, Hypothenemus Ham
ABSTRAK
A study on functional response of Cephalonomia stephanoderis Betr. to prepupal and pupal stages of Coffee Berry Borer (CBB),hypothenemus hampei Ferr. was carried out in the Entomological Laboratory of Indonesian Coffee and Cocoa Research Insitute, in Jember.
The results showed that the functional response of C. stephanoderis fitted with the Hollingis functional response type II. The attack rate (a1) of C. stephanoderis for both of the prepupal and pupal stages of CBB was 0.042 individuals per hour. The handling time (Th) of C stephanoderis on prepupal stage was longer than on pupal stage of CBB, 10.8 and-9.1 hours/individual respectively
