dc.description.abstractThis study evaluated the mortality rates of eucalyptus (Eucalyptus globulus), thyme (Thymus vulgaris), laurel (Laurus nobilis) and walnut (Juglans regia) extracts on Acanthoscelides obtectus and Callosobruchus maculatus adults and also longevity, the number of eggs laid and the number of adults hatching from these eggs. The plant extracts with the highest mortality on the first day in the contact effect trials were J. regia (86.66%) in A. obtectus, J. regia (33.33%) and T. vulgaris (18.33%) in C. maculatus. In the repellent effect trials, T. vulgaris (80.00%) in A. obtectus and L. nobilis (96.66%) in C. maculatus were detected in the group aerated for 1 hour. In contact effect trials, the shortest longevity was L. nobilis (12.87 days) in A. obtectus, while J. regia (6.00 days) was found in C. maculatus. The number of eggs laid and the number of adults emerged were determined at least in J. regia in both insect species. On the other hand, in the repellent effect trials the shortest longevity in A. obtectus was determined in T. vulgaris, the number of eggs laid and the number of adults emerged from the eggs were the lowest in T. vulgaris and L. nobilis in 1 hour aerated group. In C. maculatus, the shortest longevity was found in L. nobilis, the lowest number of eggs laid in T. vulgaris and L. nobilis, and the number of adults emerged from eggs in T. vulgaris, E. globulus and L. nobilis. According to the results, in addition to the toxic effects of these plants, it was found that all plant extracts had an inhibitory effect on egg laying and the number of adults hatching from these eggs was much lower than the control group. It can be argued that in addition to their insecticidal effects on insects, the plant extracts used also affect ovulation physiology and reduce adult emergence.
