摘要
研究结果表明,月季桑拟轮蚧在三门峡市1 a发生2代,以受精的雌成虫越冬.翌年4月下旬开始产卵,5月上中旬为产卵盛期.雌雄性比为1:2.8,平均产卵量86～108粒.雄成虫具群居性、毁灭性危害.天敌昆虫主要有红点唇瓢虫、黑缘红瓢虫、中华圆蚧蚜小蜂等.田间药效试验证明,在1龄若虫期防治效果优于介壳形成期,若虫期防治可选用40％速扑杀乳油600倍液、1.2％苦·烟乳油2 500倍液;介壳形成期可选用1.2％苦·烟乳油2 500倍液、55％氯氰·毒死蜱乳油1 500倍液.
Abstract
The study results indicate that Pseudaulacaspis pentagona exhibits two generations annually in Sanmenxia,with fertilized female adults overwintering.Egg laying begins in late April of the following year,pea-king in early to mid-May.The male to female ratio is l:2.8,with an average egg production of 86～108 per female.Male adults exhibit gregarious behavior and cause destructive damage.Predatory insects such as Chilo-corus kuwanae Silvestri,Chilocorus rubidus Hope,and Pteroptrix chinensis(Howard)serve as primary natural enemies.Field trials demonstrated that control efficacy during the first instar nymph stage surpassed that during the scale formation stage.Effective control methods during the nymph stage included 600-fold dilutions of 40％methidathion EC and 2 500-fold dilutions of 1.2％Matrine·Nicotine EC.During the scale formation stage,treatments with 2 500-fold dilutions of 1.2％Matrine·Nicotine EC and 1 500-fold dilutions of 55％cyper-methrin·chlorpyrifos EC are recommended.
