Efficacy of Avermectin B1 dust and bait formulations in new simulated and accelerated field tests

IRG/WP 1257

G R Esenther

Avermectin B1 on a silica carrier dust was used in dust and bait formulations whose efficacy against Reticulitermes flavipes was assessed in new simulated and accelerated field tests. A 0.5 mg avermectin/mg dust and a bait with 50 ppm avermectin in paper pulp sandwiched between pieces of corrugated boxboard caused nearly complete mortality in bioassays and suppression of foraging in field tests. These results indicate that the formulations can be developed into control effective gallery injection and/or bait treatments.
