Investigation of breeding system and integrated control of Incisitermes minor

从日本和歌山县小泽川的木材上采集了干木白蚁Incisitermes Minor(Hagen)的伪门。利用微卫星标记对个体进行鉴定，结果表明，群体内近亲交配系数均大于0.5，表明部分群体间可能存在群体内近亲繁殖。由于某些群体中每个座位的等位基因数大于4个，因此，来自不同群体的个体可以混杂在一起。经皮下注射硼酸钠(10,000 mg/kg)不会导致小斑潜蝇的灭绝。由于小头金龟子个体的梳理活动频率较低，有效成分的扩散不可能活跃。在口服给药的情况下，健康个体的硼剂量大约是死亡个体的三倍。硼摄入量与硼酸盐杀虫活性之间未见正相关关系。

Pseudogates of the dry-wood termite Incisitermes minor (Hagen) were collected from infested timbers in Kozagawa, Wakayama Prefecture, Japan. Assessment of the individuals using microsatellite markers showed that the coefficient of inbreeding was higher than 0.5 and suggested that inbreeding within colonies could exist among some colonies. Mixing of individuals from different colonies could occur in I. minor, because number of alleles per locus was greater than four in some colonies.Dermal administration of sodium salts of boric acid (10,000mg/kg) did not lead to the annihilation of I. minor. Diffusion of active ingredients could not be active because of low frequency of grooming activity among I. minor individuals. Dose of boron in sound individuals was about three times greater than that in dead individuals in the case of oral administration. Positive correlation between intake amount of boron and insecticidal activity of sodium salts of boric acid was not observed.
