摘　　要：Insect CAPA neuropeptidesare considered to affect water and ion balance by mediating the physiological metabolism activities of the Malpighian tubules.In previous studies,the CAPA-PK analogue 1895(2Abf-Suc-FGPRLamide)was reported to decrease aphid fitness when administered through microinjection or via topical application.However,a further statistically significant decrease in the fitness of aphids and an increased mortality could not be established with pairwise combinations of 1895 with other CAPA analogue.In this study,we assessed the topical application of new combinations of 1895 with five CAPA-PVK analogues on the fitness of aphids.We found that 1895 and CAPA-PVK analogue 2315(ASG-[β3L]-VAFPRVamide)was statistically the most effective combination to control the peach potato aphid Myzus persicae nymphs via topical application,leading to 72%mortality.Additionally,the combination(1895+2315)was evaluated against a selection of beneficial insects,that is,a pollinator(Bombus terrestris)and three natural enemies(Chrysoperla carnea,Nasonia vitripennis,and Adalia bipunctata).We found no significant influence on food intake,weight increase,and survival for the pollinator and the three representative natural enemies.These results could facilitate to further establish and generate CAPA analogues as alternatives to broad spectrum and less friendly insecticides.
