温度对益蝽的生长发育和种群生命参数的影响
Development and Population Parameters of Picromerus lewisi Scott(Hemiptera:Pentatomidae)at Different Temperatures
摘要
Abstract
Picromerus lewisi Scott is a predatory insect.The effects of temperature on growth and development and population parameters of P.lewisi were investigated for the purpose of improving the rearing efficiency.At the six temperatures of 18℃,21℃,25℃,28℃,32℃and 36℃,P.lewisi could develop successfully between 18 and 32℃,while the eggs did not hatch at 36℃.The development rate of P.lewisi was linearly and positively correlated with the temperature between 18 and 32℃,which yielded an equation of Y=0.002533X―0.03648.The degree-day requirements was 394.7 DD,and the developmental threshold temperature was 14.40℃.At 32℃,the developmental period from egg to adult was the shortest(22.40 d).The temperatures exerted no influence on weight of P.lewisi That was larger in females than in males.The results of population life table showed that the net reproductive rate was the highest at 28℃(179.50),and the generation time was the shortest(57.50 d),which was seconded by those at 25℃(125.64 and 64.59 d,respectively).关键词
