Effects of Some Entomopathogen Fungi on Apis mellifera L. and Bombus terrestris L.
Abstract
Bees are essential
elements of agricultural production because of their role in pollination.
However, some practices during production, especially pesticide applications
have negative effects on bee life and behaviours. In order to decrease the side
effects of pesticides, alternative methods, especially biological control,
gained importance. In this study, effects of preparations containing; Beaveria bassiana, Verticillium lecanii and Metarhizium
anisopliae var. anisopliae, and
also Chlorpyrifos-ethyl for comparison, on Apis
mellifera and Bombus terrestris,
were investigated. Preparations were applied with two different methods;
directly as food and by spraying, with concentrations recommended by the
producer companies. In the first method, bees were fed with 5 ml solutions of
the preparations mixed with sucrose solution and antenna, wing, leg and abdomen
movements of the bees were controlled and scored 4 hours after applications. In
the second method, bees were sprayed with the preparations and mortality rates
were found. As a result of feeding method, entomopathogen preparations slightly
affected the movement of the honey bees, while Chlorpyrifos-ethyl, almost
totally inhibited their movement. Similarly, entomopathogens had no harmful
effect on the movement of bombus bees, but the insecticide totally inhibited
their movement. In the spraying method, the insecticide killed all the
individuals of both bee species, while entomopathogens caused the death of only
a few individuals.
