Parasitic wasps attracted by the sex pheromone of their coccid host

  title={Parasitic wasps attracted by the sex pheromone of their coccid host},
  author={M. Sternlicht},
Sticky traps baited with live virgin females of the California red scale, placed in citrus groves to capture male scales, also attracted parasitic wasps ofAphytis spp. The number of wasps captured per trap (>500) reached up to 75 % of all insects caught in some citrus groves not treated with pesticides.Laboratory experiments withAphytis melinus andA. coheni and other wasps, carried out simultaneously in two different olfactometers, showed that the two species ofAphytis were highly responsive to… Expand
Walk this way, fly that way: Goniozus jacintae attunes flight and foraging behaviour to leafroller host instar
Parasitoids exhibit distinct behaviours while foraging for their herbivorous hosts. Some are specialised with respect to the host stage they can utilise and even the age of individuals within aExpand
Effect of the California red scale Aonidiella aurantii sex pheromone on the natural parasitism by Aphytis spp. in Mediterranean citrus
Results suggest a possible kairomonal effect of the CRS pheromone on A. chrysomphali, a native Aphytis species introduced to the Mediterranean by a CRS parasitoid introduction. Expand
Dispersal of Aphytis melinus (Hymenoptera: Aphelinidae) after augmentative releases in citrus orchards
The spatial dispersal of the California red scale parasitoid Aphytis melinus DeBach was evaluated in the field after augmentative releases and the results are discussed in the context of the biological control of California red Scale in citrus orchards by means of wasp releases. Expand
For sex and more: attraction of the tephritid parasitoid Psyttalia concolor (Hymenoptera: Braconidae) to male sex pheromone of the olive fruit fly, Bactrocera oleae
This study increases the knowledge of the reproductive biology of P. concolor, highlighting a case of chemical espionage in which a sex pheromone component from adult stages of the host is exploited both as a foraging kairomone by female parasitoids and as a sexual kairmone by male wasps. Expand

Evaluation of d-Limonene and β-Ocimene as Attractants of Aphytis melinus (Hymenoptera: Aphelinidae), a Parasitoid of Aonidiella aurantii (Hemiptera: Diaspididae) on Citrus spp.
The application of VOCs released from herbivore-infested plants may help to enhance the effectiveness of bio-control programs and parasitoid mass-rearing techniques. Expand
Mate Finding Via a Trail Sex Pheromone by Aphytis melinus DeBach (Hymenoptera: Aphelinidae) Males
The results of this study support a hypothesis in which A. melinus males searching on substrates on which females may be present rely exclusively on a trail sex pheromone to locate mates. Expand

Reactions of the egg parasitoid Trichogramma evanescens Westw. to certain insect sex pheromones
The egg parasitoid, Trichogramma evanescens Westw. was found to be attracted by certain insect sex pheromones. The two synthetic sex pheromones of Pectinophora gossypiella i.e., Albamy and PMWExpand
Recent records of mealybugs and their parasitoids in Nelson pipfruit orchards
A combination of monitoring methods, including possible kairomonal responses of mealybug Parasitoids to host pheromones and rearing parasitoids from fruit and foliage naturally infested with mealybugs, may provide the best assessment ofIalybug parasitoid diversity and abundance in orchards.

Effects of the Food Plant of California Red Scale, Aonidiella aurantii (Mask.) on Reproduction of its Hymenopterous Parasites
A long period of speculation on the existence of strains of California red scale immune to attack by parasites culminated in the discovery by Flanders and Smith (1942) that the hymenopterous parasite Habrolepis rouxi comp. Expand
Marking and Recapture of California Red Scale for Field Studies
Laboratory-reared adult males of Aonidiella aurantii (Maskell) were tagged by dusting the host lemons with Calco® oil blue RA dye just before emergence of the insects, resulting in the formation of a distinct blue spot. Expand
