We assessed the nontarget effects of ultra-low-volume ULV aerial adulticiding with two new water-based, unsynergized pyrethroid formulations, Aqua-K-Othrine FFAST antievaporant technology, 2 deltamethrin and Pesguard S102 10 d-phenothrin. A helicopter with GPS navigation technology was used. One application rate was tested per formulation that corresponded to 1.00 g AIha of deltamethrin and 7.50 g AIha of d-phenothrin. Three bene cial nontarget organisms were used honey bees domesticated hives, family Apidae Apis mellifera L. mealybug destroyers, family Coccinellidae Cryptolaemus montrouzieri Mulsant and green lacewings, family Chrysopidae Chrysoperla carnea Stephens.Nosigni cant nontarget mortalities were observed.No bees exhibited signs of sublethal exposure to insecticides. Beehives exposed to the insecticidal applications remained healthy and productive, performed as well as the control hives and increased in weight 25-30, in adult bee population 14-18, and in brood population 15-19.
