Development and reproduction of the parasitic wasp Allotropa subclavata (Hymenoptera: Platygastridae) on the Japanese mealybug Planococcus kraunhiae (Hemiptera: Pseudococcidae)
Applied Entomology and Zoology 54 (3), 313-318
Abstract: Allotropa subclavata Muesebeck (Hymenoptera: Platygasteridae) is one of the most effective natural enemies of the Japanese mealybug Planococcus kraunhiae (Kuwana) (Hemiptera: Pseudococcidae), a serious pest in Japanese orchards. We examined the developmental and reproductive traits including host deprivation effect on oviposition of A. subclavata to evaluate its potential as a biological control agent for P. kraunhiae. The developmental zero and effective accumulative temperature of A. subclavata females and males reared on second-instar nymphs, a suitable host stage for this parasitoid, were 12.3 °C and 514.3 degree days and 12.8 °C and 432.8 degree days, respectively. The longevity of A. subclavata maintained with honey was longer than that of those maintained with water or no feeding. The average numbers of mature eggs in ovaries of the 0- and 30-day-old A. subclavata females were 301.1 and 290.4, respectively, and were not significantly different. Offspring production of 30-day-old A. subclavata females was approximately 80% that of 0-day-old female parasitoids. On average, 50% of all eggs were laid within 24 h of the start of oviposition. The intrinsic rate of increase at 25 °C was 0.115, which is considered to be approximate to that of the host, P. kraunhiae.
