Abstract
Studies on the effect of black pepper. onion and garlic powders on
reproduction of Cal/osobruchus maculatus and the correlation of this effect to the
sterility, morphological and histological changes in the ovaries were carried out.
Results showed that there were progressive increase In sterility as the
concentrallon of plant powders Increased. The tested materials reduced the size of
the ovarioles of females resulted from treated seeds. The decrease in me sures of
ovarlcles and Spermatheca were connected with the increasing of plant powders
concentration.
Some damaged were observed in ovarioles offemales resulted fro treated
seeds with Lc25 and Lc50 of plant powders. Oosyte increase in size and shape
changed from spherical in primary oosyte to rectangle shape in case of black pepper
and onion whereas, the shape becomes oval in garlic case. In the germarium Ihe
nuclei lose their normal shape in the nuclear membrane is irregular the fo licle cells
and the follicular epithelium become thinner, loses Its contact with the oosite and
becomes the vaculated.
