“…Ooencyrtus telenomicida is a minute encyrtid egg parasitoid of several phytophagous bugs of different heteropteran (Coreidae, Pentatomidae, Scutelliridae) and lepidopteran (Lymantriidae, Notodontidae, Thaumetopoeidae) families (Japoshvili and Noyes 2006). Ooencyrtus telenomicida is also reported as a facultative secondary parasitoid of Scelionidae (Hymenoptera) (Catalán and Verdù 2005).…”

Intraguild interactions between two egg parasitoids, Trissolcus basalis (Hymenoptera: Scelionidae) and Ooencyrtus telenomicida (Hymenoptera: Encyrtidae), exploring egg masses of the Southern Green Stink Bug (SGSB) Nezara viridula (Heteroptera: Pentatomidae), were investigated in laboratory conditions by single, simultaneous and sequential host attack experiments. Mortality of N. viridula eggs was higher in simultaneous and sequential releases compared to single species releases. In simultaneous host exploitations, T. basalis females displayed an aggressive behavior against O. telenomicida females. The outcome of multiparasitism showed that interspecific larval competition was dominated by O. telenomicida regardless of the sequence in which oviposition occurred and which parasitoid was or was not simultaneously released in the patch. Finally, O. telenomicida can successfully develop in hosts already parasitized by T. basalis up to seven days earlier, acting as a facultative hyperparasitoid, so that intraguild predation (IGP) also occurred. The ecological factors that allow species coexistence and the role played by competition in biological control\ud programs are discussed

“…During the oviposition and before laying an egg, females feed on host fluids following drilling of the host chorion (host feeding). This species is native from the Palaearctic region and it has been recorded to occur from West to East across Europe, Asia, and Sub Saharan Africa (Zhang et al 2005;Japoshvili and Noyes 2006).…”

“…Ooencyrtus telenomicida is a generalist egg parasitoid present across Europe, Asia, and Sub Saharan Africa (Zhang et al 2005;Japoshvili and Noyes 2006). It has been recorded to parasitize several herbivore insects of heteropteran families, Coreidae, Pentatomidae, Scutelliridae, and lepidopteran families, Lymantriidae, Notodontidae and Thaumetopoeidae (Japoshvili and Noyes 2006). This wasp is also reported as a facultative secondary parasitoid of hymenopteran Scelionidae (Japoshvili and Noyes 2006) and in particular of T. basalis (Catalán and Verdú 2005).…”

Behavioral response of the egg parasitoid Ooencyrtus telenomicida to host-related chemical cues in a tritrophic perspective

et al. 2010

The response of the generalist egg parasitoid Ooencyrtus telenomicida (Vassiliev) (Hymenoptera: Encyrtidae) to host-related chemical cues from tomato plants, Solanum lycopersicum L., and adults of Nezara viridula (L.) (Heteroptera: Pentatomidae) was investigated in laboratory-based no-choice and paired-choice tests. In Y-tube olfactometer experiments, when female wasps were exposed to volatiles from plants in different conditions, they were attracted only to volatiles produced by N. viridula adult-infested tomato plants. When female wasps were exposed to adults of N. viridula, they were attracted to volatiles from virgin males, and, at a lower level, to volatiles from mated females in preoviposition state. Finally, studies in open arena showed that chemical footprints left by adults of N. viridula did not induce arrestment responses in wasp females. These results are discussed in terms of extrinsic competition with other beneficial egg parasitoids that in field can compete for the same egg mass, since intraguild interactions may affect the success of a biological control program
