Investigation of breeding system and integrated control of Incisitermes minor

从日本和歌山县小川的侵染木材中采集了干木白蚁的假虫。用微卫星标记评价个体近交系数大于0.5，表明部分群体之间可能存在群体内近交。由于每个位点的等位基因数大于4个，在某些群体中，不同群体的个体可能会发生混合。皮肤给药硼酸钠盐（10,000mg/kg）不导致I. minor的湮灭。有效成分的扩散不可能有效，因为在I. minor个体中梳理活动的频率较低。在口服给药的情况下，健康个体的硼剂量约为死亡个体的三倍。硼的摄取量与硼酸钠盐的杀虫活性无正相关。

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.
