Changes in the ovaries of olive flies (Dacus oleae (Gmelin)) during the summer, and their relationship to temperature, humidity and fruit availability

摘要: . 1. Examination of the ovaries female olive flies (Dacus oleae) from wild populations on Corfu during summer months 1975 indicated that all were non-gravid for a period several weeks June and July terminal follicles resorbed. 2. Experiments in outdoor cages fruits could stimulate ovarian development months. 3. constant temperature cabinets high temperatures (i. e. 26–29°C) conjunction with low humidity (45 ± 5°%) inhibited maturation. 4. Whereas presence offset effects at 26°C flies, 29°C very few able to mature their ovaries. 5. It is suggested it interaction temperature, access fruit which determine when maturation ceases recommences months.
