Influence of selected biogenic amines on development and demographic parameters of a temperate population of Cinara (Cupressobium) cupressi (Hemiptera, Aphididae)

Abstract Cinara ( Cupressobium ) cupressi , the cypress aphid, is a serious pest of Cupressus spp. and other Cupressaceae, considered to be one world’s 100 worst invasive alien species. The potential influence selected biogenic amines (tryptamine, tyramine, putrescine, cadaverine) on development demographic parameters temperate population aphid was investigated under laboratory conditions. Within parthenogenetic generations, use resulted in significant reduction total fecundity average daily both fundatrix (F0) fundatrigeniae (F1), whereas this F5 generation insignificant. In all generations treated with amines, dissected female abdomen contained greater number mature embryos compared control samples. Cadaverine caused marked changes body length viviparous studied developing embryos, sample. did not significantly affect eggs produced by oviparous females but had an impact their lifespan. Our results indicate that application may disrupt feeding behavior thus leads reduced fecundity, consistent observation embryo production. Consequently, bioamines can used as alternative agents important
