Development and reproduction of Capulinia sp. near jaboticabae von Ihering (Hemiptera: Eriococcidae) on Guava

Abstract:

During January-October 1999 studies on the life history and the fertility of Capulinia sp. were conducted. Duration of development, sex ratio, fecundity (eggs/female) and adult longevity were evaluated. Eggs hatched after 8 days. Th e female undergoes two and the male four nymphal instars. First instar nymphs lasted 8.48±0.03 days. Th e duration of the female second nymphal instar and the longevity of the adult were 6.05±0.03 y 46.67±0.61 days respectively. Th e male second, third and forth nymphal instars as well as the longevity of the adult were 4.57±0.02, 2.04±0.01, 3.66±0.02, 1.10±0.01 days respectively. Th e sex ratio resulted of 1:1. Th e fecundity was 2511.94±57.20 eggs/female. Th e high fecundity explains the possibilities of developing large populations like those observed in orchards during the initial colonization by this insect. Th e life history are basic for understanding entomological problem especially for species like Capulinia sp. on guava. © 2004, Sociedad Venezolana de EntomologÍa.
