对日本本土的共1449株苏云金芽孢杆菌菌株进行了针对两种长角亚目害虫——骚扰库蚊（蚊科）和白星蛾蚋（蛾蚋科）的杀幼虫活性筛选。在H血清型3abc（库斯塔克亚种）、3ade（福冈亚种）、4ac（肯尼亚亚种）、7（ aizawai亚种）、11ac（九州亚种）和29（天城亚种）中，对蚊子有特异性的菌株数量丰富，而对蛾蚋有特异性的菌株主要在H血清型17（东北亚种）中发现。对两种昆虫都有毒性的菌株在H血清型10（达姆斯塔特亚种）和17/27中最为常见。7株选定的苏云金芽孢杆菌菌株对库蚊和/或白星蛾蚋有高毒性。这些菌株的包含体蛋白的SDS - PAGE图谱存在多样性。
A total of 1449 Bacillus thuringiensis strains, indigenous to Japan, were screened for larvicidal activity against two nematoceran insect pests, the mosquito, Culex pipiens molestus (Culicidae), and the moth-fly, Telmatoscopus albipunctatus (Psychodidae). Mosquito specific strains were abundant in H serotypes 3abc (serovar kurstaki), 3ade (fukuokaensis), 4ac (kenyae), 7 (aizawai), 11ac (kyushuensis) and 29 (amagiensis), while moth-fly specific strains were predominantly found in H serotype 17 (tohokuensis). Strains toxic to both insects were most frequently detected in H serotypes 10 (darmstadiensis) and 17/27. Seven selected B. thuringiensis strains were highly toxic to Culex and/or Telmatoscopus. There was a diversity in SDS-PAGE profiles of inclusion proteins of these strains.
