曾有记载:日本方头甲[Cybocephalus nipponicus Endrdy-Younga(Cybocephalidae)]在日本是桑盾蚧及矢尖蚧的捕食性天敌,但还无记载是植食性螨类的捕食性天敌。 日本方头甲雄虫羽化后4~5天,雌虫则在羽化后2天即交尾,从交尾至产卵为2~6天,平均为4天;产卵前期为6~10天,平均8天,卵期平均为6.23天,幼虫期平均为15.77天,蛹期15.67~19.12天,即平均一生发育期为37.07~41.12天。雌雄性比为1:0.77。雌虫寿命最长191天,最短66天,平均143.9天;雄虫寿命最长193天,最短35天,平均122.8天。根据对捕食对象嗜好性试验:日本方头甲喜食盾蚧的2龄幼虫,很少取食雌成虫,对红蜘蛛则偏嗜卵,亦能取食若虫及雌成虫。以盾蚧为食时能进行生殖,但以红蜘蛛为食料时则不能产卵,
It has been documented that Cybocephalus nipponicus Endrdy-Younga (Cybocephalidae) is a predatory natural enemy of Sanguineus and Agkistrodon acutus in Japan, but there is no record of predatory natural enemies of phytophagous mites. 4 ~ 5 days after the emergence of T. australis, the females in the eclosion 2 days after the mating, from the mating to spawn for 2 to 6 days, an average of 4 days; spawning period of 6 to 10 days, the average 8 days, an average of 6.23 days eggs, larvae averaging 15.77 days, pupal period 15.67 ~ 19.12 days, the average life span of 37.07 to 41.12 days. Male to female ratio was 1: 0.77. Female longest 191 days, the shortest 66 days, an average of 143.9 days; male longest 193 days, the shortest 35 days, an average of 122.8 days. According to preference test of predators: Japanese side head feeding Dioscorea sinensis second instar larvae, feeding on female adults rarely on spider mite eggs, but also feeding on nymphs and female adults. In order to reproduce the food when the shield scales insects, but the spider mites feed can not spawn,
