Abstract
This research aimed to find plant essential oils with a strong fumigant-specific toxicity effects against
Callosobruchus maculatus and Bruchus rufimanus, but which have lower side effects on their parasitoids
wasps Dinarmus basalis and Triaspis luteipes. For that, the essential oils of Artemisia herba-alba,
A. campestris and A. absinthium were investigated for their chemical composition using GC and GCeMS
analysis and were used in a manner that combined exposure to their essential oils with parasitoids
releases. Essential oils were assessed for their direct fumigant toxicity against both bruchid beetles and
for their residual effects on parasitism rates and pests offspring control. The introduction of D. basalis and
T. luteipes adults were done 6 days after the oil application.
The results showed that A. campestris essential oil can be considered compatible with the natural
enemies for controlling stored food legume beetles. When the parasitoids D. basalis and T. luteipes were
released six days after the application of A. campestris oil, the parasitism rates reached 13.6% and 80.3%
for C. maculatus and B. rufimanus respectively. Moreover, 26.6% of C. maculatus offspring have emerged,
while for B. rufimanus a complete lack of offspring was recorded. Adults of D. basalis were more susceptible to oils vapours than adults of T. luteipes.
The release of parasitoids could better be combined with essential oils of A. campestris, as this oil had
more pronounced effects on the beetles than on their parasitoids, in particular for the case of B. rufimanus
and T. luteipes.
