| role of cuticular hydrocarbons of aphid parasitoids in their relationship to aphid-attending ants. | lysiphlebus cardui, the dominant aphidiid parasitoid of the black bean aphid,aphis fabae cirsiiacanthoidis (afc), on creeping thistle, is able to forage in ant-attended aphid colonies without being attacked by ants. several behavioral observations and experimental studies led to the hypothesis thatl. cardui mimics the cuticular hydrocarbon profile of its host aphid. chemical analysis of the cuticular extracts revealed that bothl. cardui and afc exclusively possess saturated hydrocarbons:n-alkane ... | 1996 | 24227578 |
| long-term phenological trends, species accumulation rates, aphid traits and climate: five decades of change in migrating aphids. | aphids represent a significant challenge to food production. the rothamsted insect survey (ris) runs a network of 12·2-m suction-traps throughout the year to collect migrating aphids. in 2014, the ris celebrated its 50th anniversary. this paper marks that achievement with an extensive spatiotemporal analysis and the provision of the first british annotated checklist of aphids since 1964. our main aim was to elucidate mechanisms that advance aphid phenology under climate change and explain these ... | 2015 | 25123260 |
