Abstract: Hypothenemus hampei is a coffee berry borers (CBB) that is difficult to control because it lives inside the coffee berries. Blastospores of entomopathogen fungal are expected to be effective in controlling these pests. The purpose of this study was to evaluate the ability of blastospores Paecilomyces fumosoroseus, Metarhizium anisopliae and Lecanicillium lecanii to infect, kill and inhibit the development of H. hampei on coffee cherries in the laboratory. The study was conducted from March to December 2019 at the Plant Protection Laboratory, Indonesian Industrial and Beverage Crops Research Institute, Sukabumi. The study used 14 treatments, namely 3 types of fungi are P. fumosoroseus, M. anisopliae and L. lecanii with every 4 densities are 108, 107, 106, and 105 blastospores/ml, positive control using botanical insecticides (Biotris) and negative control, and repeated 4 times. The parameters observed were mortalities, number of bor holes, and insect development after treatment. The results showed that all blastospores were able to infect and kill H. imago in the laboratory. The highest mortality occurred in the treatment of P. fumosoroseus with 108 blastospores/ml densities (P1) by 39.91%. Blastospores of 3 entomopathogens were able to inhibit the number of bor holes on the coffee cherries, with the highest inhibition in the treatment of L. lecanii 106 blastospores/ml (L3) by 28.57%. All types of blastospores can also inhibit insect development in the coffee cherries. Treatment of M. anisopliae 108 blastospore/ml (M1) was able to reduce the number of eggs and nymphs by 78.69% and 74.24% respectively compared to negative controls. Blastospores from three types of entomopathogens have the potential to be developed as bioinsecticides to control CBB.
