Resumo
O presente trabalho teve por objetivo estudar os aspectos biológicos, morfológicos e comportamentais de uma linhagem unipariental de Aspidiotus nerii Bouché, 1833 (Hemiptera: Diaspididae), sob condições controladas (25±1oC, 70±10% de UR e 12 horas de fotofase), tendo abóboras híbridas cabotiá como hospedeiro. Ninfas recém-eclodidas foram transferidas da criação massal para abóboras cabotiá, devidamente higienizadas, dispostas em câmaras climatizadas. O período médio para fixação das ninfas móveis foi de 2,4±0,33 horas. A duração média do 1° e 2° estádios, após a fixação das ninfas, foi de 8,3±0,06 e 19,4±0,11 dias, respectivamente, totalizando fase ninfal média de 27,9±0,11 dias. Das ninfas que atingiram a fase adulta, 36 fêmeas foram acompanhadas diariamente até o final do ciclo. A duração média dos períodos pré-reprodutivo e reprodutivo foi de 17,3±0,18 e 68,2±4,33 dias, respectivamente. O número total médio de ninfas/fêmea foi 175,5±10,29 e o número médio de ninfas/fêmea/dia foi 2,7±0,11. A longevidade média das fêmeas foi 100,5±4,51 dias.
The objective of this work was to study the biology, morphology and behavior of Aspidiotus nerii Bouché, 1833 (Hemiptera: Diaspididae) under controlled conditions (25±1°C, 70±10% R.H. and 12 hours of photophase), using cabotiá cucumber pumpkins as hosts. Nymphs of the 1st stage obtained of mass rearing (mother culture) were transfered to cabotiá pumpkins, properly cleaned and disposed in acclimatized cameras. The medium period for fixation of the nymphs was of 2.4±0.33 hours. The 1st and 2nd stages, after the fixation of the nymphs, lasted 8.3±0.06 and 19.4±0.11 days, respectively, totalizing a nymphal phase of 27.9±0.11 days. 36 females were observed daily until the end of the cycle. The pre-reproductive and reproductive periods lasted 17.3±0.18 and 68.2±4.33 days, respectively. The medium total number of nymphs/female was 175.5±10.29 and the medium number of nymphs/female/day was 2.7±0.11. The female's longevity was 100.5±4.51 days.
