摘要 [目的] 探究不同颜色产卵介质对蠋蝽产卵习性的影响,为蠋蝽规模化繁殖提供科学依据。[方法]在室内条件下探索6种不同颜色产卵介质(白色为对照组)对蠋蝽产卵习性的影响。[结果]蠋蝽在6种不同颜色产卵介质的环境中产卵量在100~130粒,无显著差异;产卵次数5~6次,也无显著差异;产卵期存在显著差异,经LSD比较,在绿色产卵介质中产卵期最短为25.20 d,对照组产卵期最长为35.46 d。[结论]蠋蝽在绿色产卵介质的环境中,产卵效率显著提高。该研究结果为人工规模化蠋蝽饲养提供理论指导。

Abstract [Objective]To explore the effects of different color oviposition media on the oviposition habit of Arma chinensis(Fallou),to provide scientific basis for largescale Arma chinensis(Fallou) breeding.[Method]Six different color oviposition media(white as contrast) were investigated on Arma chinensis (Fallou) oviposition behavior under indoor conditions.[Result] Fecundity of Arma chinensis(Fallou) were between 100 and 130 without significant difference when exposed to six different color oviposition media.The number of oviposition was 5-6 times also without significant difference.There were significant differences in the oviposition period.According to LSD comparison,the oviposition period in the green medium was the shortest with 25.20 days,while the longest period in the contrast was 35.46 days.[Conclusion]The results of this study showed that Arma chinensis (Fallou) oviposition efficiency was significantly improved when treated with green oviposition media.These results provide theoretical guidance for Arma chinensis (Fallou) feeding on artificial scale.

蠋蝽[Arma chinensis (Fallou)]属半翅目(Hemiptera) 蝽科(Pentatomidae)益蝽亞科(Asopinae)蠋蝽属(Arma),是一种重要的捕食性天敌昆虫,其2龄若虫至成虫均以肉食性为主[1-3]。蠋蝽捕食范围广,可捕食鞘翅目、鳞翅目、半翅目等中植食性昆虫40余种[1,4],尤其是对农林业害虫双斑长附萤叶甲[Monolepta hieroglyphica(Motschulsky)]、甜菜夜蛾(Spodoptera exigua Hubner)、斜纹夜夜蛾[Spodoptera Latura (Fabricius)]、草地贪夜蛾[Spodoptera frugiperda( J.E.Smith)]、美国白蛾(Hyphaunria cunea)、榆紫叶甲(Ambrostoma quadriimopressum Motschulsky)等害虫有较好的控制作用[5-11]。此外,蠋蝽分布较广泛,在北京、吉林、黑龙江、辽宁、贵州等20余个省都有分布记载[12-13]。

近年来关于蠋蝽形态学、生物学、人工饲养、营养基因组学、储存技术、控害能力等方面的报道很多[2],主要集中于食物种类、温度、湿度以及光照对蠋蝽产卵习性的影响,但有关产卵介质对蠋蝽产卵习性的影响尚未见研究。蠋蝽的产卵行为对人工扩繁有重要意义,因而选择有效的产卵介质可提升蠋蝽产卵效能,降低当前繁殖过程中单对饲养的成本。……
