Résumé:
in organic agricultura, famlers aim the use of insecticides to control
pests, however, these compounds can achieve insects do not hall the diverse culturas.
This work aims to study the toxicity of garlic oil to Apis mellifera bens under controlled
conditions. Bioassavs were carried out at the Entomology Laboratory of the Federal
University of Campina Grande, Campus de Pombal. If garlic oil used in three different
âactions (0.25%, 0.50% and 1 .0%) and added to the "candy" and water. The workers
recently emerged have been selected by dize and color, distributed set of 20 insects per
wooden box measuring 1 1 cm long by 1 1 wide and 7 cm high, in three replications and
control, making boxes 12 and 240 worker bees , they were placed in BO D with
temperature adjusted to 32 C and 70% humidity. The control group received only the
candy and water. The insects received the candy of treatment with the plant powder.
The results of statistical analysis was obtained in the comparison between the
concentrations ofthe treatment and the control group in garlic oil intake experiment. For
data analysis we used the nonparametric test Log Rank Test, the comparison of survival
It was observed that the survival of bens was reduced with the use of diet
containing the compound of garlic oil. The control bens remained avive until 20 days
and for those treated with 0.25%, 0.50% and 1.0% respectively showed 12, 13 and 06
days survival, suggesting that there is a toxic effect of gar]ic oi] on workers of ]pís
