Abstract.  Diachasma alloeum is a braconid wasp that parasitizes hawthorn‐infesting Rhagoletis pomonella and blueberry‐infesting Rhagoletis mendax, both tephritid fruit fly sibling species. The behavioural responses of male D. alloeum originating from both fruit fly host species to hexane extracts of conspecific females originating from both host species and females of various mating status are investigated in a laboratory Y‐tube olfactometer. Male D. alloeum originating from either R. mendax… Expand
Oviposition-deterring pheromone deposited on blueberry fruit by the parasitic wasp, Diachasma alloeum
TLDR
The length of activity of the oviposition-deterring pheromone described here should be sufficient to prevent multiple egg-laying into a host that cannot support more than one parasitoid larva, and thus reduce intraspecific competition. Expand
Sexual communication and related behaviours in Tephritidae: current knowledge and potential applications for Integrated Pest Management
TLDR
Males’ exposure to parapheromones, such as phenyl propanoids, ginger root oil and trimedlure can enhance the mating success of sterile flies used in SIT programs, and PPs are also a powerful tool to improve reduced-risk monitoring dispensers and the male annihilation technique, with low side effects on non-target insects.

Rôle de l'information dans l'acquisition des partenaires sexuels et le choix du sexe de la descendance chez les hyménoptères parasitoïdes : exemple de Venturia Canescens Gravenhorst (Hymenoptera : Ichneumonidae)
TLDR
La sex-ratio est biaisee en faveur des femelles, mais contrairement aux predictions des modeles theoriques, le choix du sexe de the descendance ne semble pas dependre des informations liees aux conspecifiques. Expand

Behavioral evidence for host fidelity among populations of the parasitic wasp, Diachasma alloeum (Muesebeck)
TLDR
It is suggested that the data herein present evidence for “host fidelity,” where populations of D. alloeum exhibit a greater tendency to mate and reproduce among the host plants of their preferred Rhagoletis hosts. Expand
FIELD OBSERVATIONS QUANTIFYING ATTRACTION OF THE PARASITIC WASP, DIACHASMA ALLOEUM (HYMENOPTERA: BRACONIDAE) TO BLUEBERRY FRUIT INFESTED BY THE BLUEBERRY MAGGOT FLY, RHAGOLETIS MENDAX (DIPTERA: TEPHRITIDAE)
TLDR
The host foraging behavior of the larval parasitoid Diachasma alloeum from natural populations was directly observed in a highbush blueberry, Vaccinium corymbosum L., plantation and the data herein are an initial step toward elucidating the cues mediating microhabitat selection by D. alloeums in blueberries. Expand
Behavioural evidence for a female sex pheromone in Cotesia flavipes (Hymenoptera: Braconidae)
TLDR
Ethological tests demonstrate that males are more attracted and also display a courtship behaviour when a filter paper containing hexane extracts from the abdomen is presented to them, indicating that the abdomen was the source of the sex pheromone of this species. Expand
Postzygotic isolating factor in sympatric speciation in Rhagoletis flies: reduced response of hybrids to parental host-fruit odors.
TLDR
It is reported that reciprocal F(1) hybrids between the apple and hawthorn host races of R. pomonella do not respond to host fruit volatiles in wind-tunnel assays at doses that elicit maximal directed flight in parental flies, suggesting that hybrids might suffer a fitness disadvantage for finding fruit in nature. Expand
Host-habitat location and host location by Diachasma alloeum Muesebeck (Hym.; Braconidae), a parasitoid of Rhagoletis pomonella Walsh (Dipt.; Tephritidae)
TLDR
It was found that probing activity and duration of stay on the fruit are strongly influenced by the presence of a Rhagoletis pomonella larva in the fruit, and host movement is the prime stimulus for the location of hosts. Expand
Antagonist effects of non‐host fruit volatiles on discrimination of host fruit by Rhagoletis flies infesting apple (Malus pumila), hawthorn (Crataegus spp.), and flowering dogwood (Cornus florida)
TLDR
The hypothesis that agonist and antagonist properties of fruit volatiles can play an important role in host recognition/discrimination by Rhagoletis flies is supported. Expand
Host fidelity is an effective premating barrier between sympatric races of the apple maggot fly.
TLDR
The results verify that host-associated adaptation can produce reproductive isolation as a correlated character (a key premise of sympatric speciation) and represents one of the few or perhaps only example in animals where the intra-specific isolating effects of specific phenotypes have been quantified in nature.

Alkadienes mediating courtship in the parasitoidCardiochiles nigriceps (Hymenoptera: Braconidae)
TLDR
Bioassays with three available alkadienes revealed that contact behaviors (antennation and mounting) are in part mediated by the (Z,Z)-7, 13-heptacosadiene and at least one other alkadiene in combination with other hydrocarbons found in males and females. Expand
Pheromone-mediated mating in the aphid parasitoid,Aphidius nigripes (hymenoptera: Aphididae)
TLDR
Field data suggest the presence of a strong diel periodicity in the emission of and/or receptivity to the pheromone in aphid parasitoid females, but more refined techniques are needed to determine if such periodicity exists in phersomone production by females. Expand
Courtship Behavior and Evidence for a Sex Pheromone in the Apple Maggot Parasite, Opius alloeus (Hymenoptera: Braconidae)
TLDR
Pheromones may provide an invaluable tool in behavioral and taxonomic studies of closely related forms and their potential in increasing the effectiveness of beneficial parasitic species is largely conjecture. Expand
