Evaluation of Metarhizium anisopliae for control of Lissorhoptrus oryzophilus in the field.

Abstract

Using Metarhizium anisopliae to control rice water weevil, Lissorhoptrus oryzophilus at the pre-oviposition stage was conducted in the field [in China]. Results showed that the adult population of L. oryzophilus was reduced by 92.5% 13 d after spraying at a rate of 1014 spores/ha. Larval and adult populations in the coming generation decreased to 2.12 and 0.30 per hill, while those in the check the populations were 8.40 and 4.17 per hill, respectively.
