Determinants of variation in the response of the aphid parasitoid Aphidius ervi to aphid sex pheromones

, 2008
Variation in parasitoid responses to semiochemicals may be influenced by genetics, phenotypic plasticity and the individual\u27s physiological state. Previous experimental work has indicated a high degree of variability among parasitoid individuals in ...

A novel Fatty Acid Binding Protein produced by teratocytes of the aphid parasitoid Aphidius ervi.

, 2005
Aphidius ervi is an endophagous braconid, parasitoid of the pea aphid, Acyrthosiphon pisum. A. ervi terato- cytes, deriving from the dissociation of the embryonic serosa, synthesize and release two major proteins into the host haemocoel.

Apparent competition between two species of aphid via the fungal pathogen Erynia neoaphidis and its interaction with the aphid parasitoid Aphidius ervi

, 2002
1. Motivated by a community study on aphids and their fungal pathogens, three hypotheses were tested experimentally to investigate the influence of the fungal pathogen, Erynia neoaphidis Remaudière and Hennebert, on aphid population and community ecology.

Rapid Responses of Winter Aphid-Parasitoid Communities to Climate Warming

Frontiers in Ecology and Evolution, 2018
Consequences of inter-annual environmental fluctuations, including those associated with climate change, can have a knock-on effect from individual to community scale.

Host Recognition and Acceptance Behavior In 2 Aphid Parasitoid Species - Aphidius-ervi and Aphidius-microlophii (hymenoptera, Braconidae)

, 1994
The host preference and acceptance behaviour of populations of Aphidius ervi Haliday and A. microlophii Pennacchio & Tremblay from southern Italy was investigated. In no host-choice conditions, A.

Qualidade de diferentes espécies de pulgões como hospedeiros do parasitóide Aphidius ervi Haliday (Hymenoptera: Braconidae: Aphidiinae)

, 2010
The suitability of Macrosiphum euphorbiae (Thomas), Aulacorthum solani (Kaltenbach) and Acyrthosiphon kondoi Shinji (Hemiptera: Aphididae) as hosts for the aphid parasitoid Aphidius ervi Haliday was evaluated by assessing host size, host preference, and ...
