ABSTRACT
ABSTRACT: The post embryonic developmental stages of Marpissa bengalensis (Araneae; Salticidac), the 2nd most abundant predatory species in citrus orchard were collected from the experimental fruit garden, department of Horticulture, located at the campus of University of Agriculture Faisalabad andstudied. Life cycle was observed in the laboratory, which started from egg sac collected from the field along with gravid female and released into the spider cages. The incubation period ranged from 5-15 days. The average eggs hatched were 23.8 eggs/cocoon and hatching % under laboratory conditions was recorded as 73.18%. The average duration of spiderlings span on their mothers back was 7 days. An overall, mean duration of 3rd spiderling stage was of 7.46 days. All spiderlings hatched from 8 cocoons. At the 4th spiderling stage, the average duration was of 10.23 days. In the 5th spiderling stage, the spiderling spent an average of 19.82 days. The 6th and 7th spiderlings stages lasted a total of 23.14 days and 25.86 days respectively. During 8th spiderling stage, the duration was maximum and it was recorded in 28.08 days. On average, from hatching to adult stage, the spiderlings lasted 137 days to attained maturity. Greater mortality was observed in the 3rd and 4th spiderling stages, decreasing thereafter and reaching zero in the 8th spiderling stage.
RESUMO
RESUMO: Os estádios de desenvolvimento pós-embrionário de Marpissa bengalensis (Araneae; Salticidac), a segunda espécie predatória mais abundante no pomar cítrico, foram coletadas no pomar experimental de frutas do Departamento de Horticultura, localizado no campus da Universidade de Agricultura de Faisalabad, onde foram estudados. O ciclo de biológico foi estudado no laboratório, em que iniciou a partir de ovos coletados de fêmeas grávidas e soltas em cativeiro. O período de incubação variou de 5-15 dias. a média de ovos incubados foram 23,8 ovos/casulo e a porcentagem de incubação em condições laboratoriais foi de 73,18%. A duração média da fase imatura a foi de 7 dias. Uma duração geral, média do terceiro estádio da fase imatura, foi de 7,46 dias de todas as fases imaturas incubadas com 8 casulos. A partir do quarto estádio da fase imatura a duração média foi de 10,23 dias. No quinto estádio de imaturação, demorou uma média de 19,82 dias. O sexto e o sétimo estádios de imaturação duraram um total de 23,14 e 25,86 dias, respectivamente. Durante o oitavo estádio de imaturação a duração foi de 28,08 dias, sendo máxima. Em média, desde a incubação até o estádio adulto, o estádio de imaturação duraram 137 dias. A maior mortalidade foi observada nos terciro e quarto estádios de imaturação, diminuindo, a partir de então, e atingindo zero no oitavo estádio de imaturação.
