Abstract

Snout beetle (Metapocyrtus (Trachycyrtus) spp.) is a destructive pest affecting strawberry and citrus production in the highland areas of the Northern Philippines. The white grubs feed on the root system of both fruit crops while the adult beetles feed on the shoots and young leaves. Infested plants become stunted and severe damage could result to wilting and death of infested plants. To develop measures to manage the pest and prevent further problems on the side effects of toxic chemicals, the effects of two fungal species as biological control agents were evaluated against the white grubs. Beauveria bassiana (Bals.-Criv.) Vuill. And four isolates of Metarhizium anisopliae (Metchnikoff) Sorokin were evaluated on strawberry and citrus. Both fungi were applied into the soil one week before transplanting the strawberry runners and citrus seedlings. Based on white grub population and their damage on sample plants, B. bassiana and M. anisopliae isolates MA-RB and MA-RBB were found effective against white grubs. Plants applied with the fungi significantly had lower white grub populations and degree of root damage, resulting to better growth and development and lower percentage of infested plants. These fungi could be integrated with other pest management methods for better strawberry and citrus production.
