[Ovarian development of Agrilus auriventris Saunders (Coleoptera: Buprestidae)]
Acta Entomologica Sinica 50 (7), 682-688
Abstract: Ovarian development of Agrilus auriventris Saunders was studied by dissecting the pupae, mated or unmated female adults fed with food, and mated females without any food. The results showed that the ovary of this pest has two ovaries, each composed of five ovarioles. Ovaries developed normally in the first two treatments of female adults fed with food, which had the longevity of about 30 days. While the mated female adults without any food had the longevity of only about 10 days, during which no eggs formed either in growth zone or maturation zone of ovarioles. Ovarian development was divided into 6 stages based on the morphological characteristics of ovarian development, the formation of eggs, eggs in the lateral oviducts and vitellogenesis: stage 0 (no oocyte stage), stage I (no yolk stage), stage II (yolk deposition stage), stage III (egg maturation stage), stage IV (peak egg deposition stage), and stage V (egg depletion stage). In mated adults with foods, mature eggs formed in 11 days after emergence, and the ovipositon duration could last as long as 22 days, with the highest fecundity of about 140 eggs per female. It is so proposed that to achieve better control effects, measuress should be taken to control the adults of A. auriventris before the stage III of ovarian development (within 10 days after adult emergence).
