We have evaluated Photorhabdus insect-related protein (Pir) from Photorhabdus asymbiotica against dengue vectors. PirAB shows larvicidal activity against both Aedes aegypti and Aedes albopictus larvae but did not affect the Mesocyclops thermocyclopoides predator. PirAB expressed the strongest toxicity compared to PirA, PirB, or the mixture of PirA plus PirB. Whether the presence of an enterobacterial repetitive intergenic consensus sequence in PirAB, but not in PirA, PirB, or the mixture of PirA plus PirB, has any impact on biological control efficacy needs further investigation.
我们评估了来自共生光杆状菌的光杆状菌昆虫相关蛋白（Pir）对登革热媒介的作用。PirAB对埃及伊蚊和白纹伊蚊幼虫均表现出杀幼虫活性，但对嗜热中剑水蚤捕食者没有影响。与PirA、PirB或PirA加PirB的混合物相比，PirAB表现出最强的毒性。PirAB中存在肠杆菌重复基因间共有序列，而PirA、PirB或PirA加PirB的混合物中不存在该序列，其是否对生物防治效果有任何影响尚需进一步研究。
