Abstract

Cotton mealybug (Phenococcus solenopsis Tinsley 1898) is one of the major sucking insect pest of cotton in Pakistan. This study was carried out during 2012 & 2013 in Multan District, Punjab, Pakistan to evaluate the response and conservation of biocontrol agents i.e. Aenasius bambawalei Hayat (= A. arizonensis Fallahzadeh, 2014) and Cryptolaemous montrouzieri Mulsant, 1850 against cotton mealybug (CMB). Biological responses of these biocontrol agents were assessed at different temperatures and humidity levels in the laboratory; which helped to design the rearing technologies for field releases. Data was collected at 100, 200 and 400 meters from NEFR surroundings after 07, 15 and 22 days of releases (DAR) of biocontrol agents. Results showed a significant decrease in CMB population; at 100 meter as 46%, 69% and 94% respectively; at 200 meter as 32%, 53% and 83% respectively; at 400 meter as 25%, 45% and 77% respectively. Cost benefit ratio of NEFR assessed was 1:1.8 and 1:3.2 when the crop losses reduced 20 to 50 percent in comparison with control field.

在巴基斯坦通过保护和增加班巴瓦伊aenasius和montrouzieri隐毛虫来合理管理扶桑球菌

棉花粉蚧(Phenococcus solenopsis Tinsley 1898)是巴基斯坦主要的棉花吸吮害虫之一。本研究于2012年和2013年在巴基斯坦旁遮普省木尔坦地区开展，目的是评价bambawalei Aenasius Hayat (= A. arizonensis Fallahzadeh, 2014)和montrouzieri Mulsant, 1850两种生物防治剂对棉粉蚧(CMB)的防治效果和保护效果。在实验室中，在不同温度和湿度水平下评估了这些生物防治剂的生物反应;这有助于田间放养技术的设计。在生物防治剂释放(DAR) 7、15和22天后，在距NEFR环境100、200和400米处采集数据。结果表明:CMB种群数量显著减少;100米分别为46%、69%和94%;200米分别为32%、53%和83%;400米分别为25%、45%和77%。经评估的NEFR成本效益比为1:8 .8和1:32 .2，作物损失比对照田减少20% ~ 50%。
