Repellency of the oily extract of neem seeds (Azadirachta indica) against Varroa destructor (Acari: Varroidae)
Experimental and Applied Acarology 56 (3), 261-270
Abstract: A crude oil extract of neem seed (Azadirachta indica, Sapindales: Meliaceae) was evaluated for repellency on Varroa destructor Anderson and Trueman. Burgerjon's tower was used to spray worker bee pupae with 0.0, 0.3, 0.7, 1.3, 2.6, 5.3, 10.6 and 21.1% neem extract concentrations. Sprayed pupae were attached to observation arenas and incubated at 32 ± 2°C and 70 ± 10% RH. The ability of V. destructor to locate and feed on treated and untreated pupae was monitored from 30 min to 72 h after spray. Higher and more stable repellency was achieved with 2.6, 5.3, 10.6 and 21.1% neem extract. At the highest concentration, 98% of V. destructor were prevented to settle on bee pupae, resulting in 100% V. destructor mortality at 72 h.
