- Abstract
This study examined the toxicity of anethole and that of the essential oils of lemongrass<italic> (Cymbopogon citratus)</italic> and sweet marigold<italic> (Tagetes lucida)</italic> to the mite<italic> Varroa destructor</italic> and to honey bee workers and larvae. Anethole was the most toxic compound to<italic> V. destructor</italic> (LC50: 304.9 <italic>μ</italic>g/ml), whereas<italic> Tagetes</italic> oil was the least toxic (LC50: 1256.27 <italic>μ</italic>g/ml). The most and least toxic compounds to worker bees were anethole and<italic> Tagetes</italic> oil with LD50s of 35942 and 85381 <italic>μ</italic>g/ml, respectively. For larvae,<italic> Tagetes</italic> oil was the most toxic compound (LD50: 9580.7 <italic>μ</italic>g/ml) and anethole the least toxic (LD50: 14518.0 <italic>μ</italic>g/ml). Anethole and<italic> Cymbopogon</italic> oil had the highest selectivity ratios. The expression of<italic> AChE</italic>, a gene that regulates the production of acetyl cholinesterase, a detoxifying enzyme, was not altered in bees treated with the plant compounds at 48 h post-treatment. This study showed that anethole and<italic> Cymbopogon </italic>oil have potential for controlling<italic> Varroa</italic> mites and seem to be relatively safe for larvae and adult honey bees.
