“…In both Cotesia species, the distal antennomeres appeared to be intimately involved in host location and recognition since they made direct contact with the body surface of the larvae. This observation corroborates findings that the distal antennomeres of braconid parasitoids possess gustatory sensillae that detect chemical stimuli associated with the host (Navasero & Elzen, 1991;Barbarossa-Tomassini et al, 1998;Canale & Raspi, 2000;Ochieng et al, 2000).…”

Abstract. The host recognition and acceptance behaviour of two braconid larval parasitoids (Cotesia sesamiae and C. flavipes) were studied using natural stemborer hosts (i.e., the noctuid Busseola fusca for C. sesamiae, and the crambid Chilo partellus for C. flavipes) and a non-host (the pyralid Eldana saccharina). A single larva was introduced into an arena together with a female parasitoid and the behaviour of the wasp recorded until it either stung the larva or for a maximum of 5 min if it did not sting the larva. There was a clear hierarchy of behavioural steps, which was similar for both parasitoid species. In the presence of suitable host larvae, after a latency period of 16-17 s, the wasp walked rapidly drumming the surface with its antennae until it located the larva. After location and antennal examination of the host, which lasted 60-70 s and 30 s, respectively, the parasitoid inserted its ovipositor. Stinging that resulted in successful oviposition usually lasted 5-6 s. In the presence of non-host larvae, the latency period was between 25-70 s, and parasitoids spent significantly more time walking and antennal drumming on larvae without ovipositing. It is likely that these two parasitoid species use their antennae for host recognition, and both their antennae and tarsi for final acceptance of a host for oviposition. In both C. sesamiae and C. flavipes tactile and contact-chemoreception stimuli from the hosts seemed to play a major role in the decision to oviposit.

“…Due to their insertion in an enlarged pit, they are also referred as coeloconica (Scheneider 1964, Ochieng et al 2000. According to Slifer (1970), these sensilla are associated to an olfactory role, perceiving long distance stimuli.…”

“…In general, the sensilla described as chaetica bear a terminal pore connected to sensorial dendrites, thus belonging to the uniporous category (Zacharuck 1985). They are also named grooved basiconic (Norton & Vinson 1974, Ochieng et al 2000 or uniporous gustatory sensilla (Isidoro et al 1996). In G. boseli, Villa & Mineo (1990a) registered them only on the ventro-lateral surface, where they occur in a number of two per antennomere, at the apical portion, from A7 to A11, and of eight on A12.…”

Neotropical Entomology 36(5): 721-728 (2007) Morfologia e Distribuição das Sensilas Antenais das Fêmeas de Gryon gallardoi (Brèthes) (Hymenoptera: Scelionidae)RESUMO -Usando a microscopia eletrônica de varredura, foram descritas e ilustradas a morfologia externa e a distribuição das sensilas antenais da fêmea de Gryon gallardoi (Bréthes), um importante parasitóide de ovos de coreídeos. As antenas são genículo-clavadas, dotadas de 12 antenômeros. Ao dois tamanhos -uma mais alongada e outra mais curta, estilocônicas, cavilhas, falciformes e tricóides, em associação ao comportamento de tamborilamento antenal de G. gallardoi são discutidos Assim, a descrição e a determinação do padrão de distribuição das sensilas antenais de G. gallardoi, no presente estudo, é um avanço no sentido de elucidar os mecanismos envolvidos nos comportamento de seleção de hospedeiros dessa espécie.PALAVRAS-CHAVE: Ultraestrutura, seleção de hospedeiros, parasitóide de ovos ABSTRACT -With the aid of scanning electron microscopy, the external morphology and distribution of the antennal sensilla were described for females of Gryon gallardoi (Bréthes), an egg-parasitoid of coreids. The we registered dorsal glands and seven types of sensilla: papillary, chaetica of two sizes -long and short types, styloconic grooved-peg, sickle-shaped and trichodea with numerical and spatial variation G. gallardoi antennal drumming behavior. Thus, the determination and the description pattern of antennal sensilla in G. gallardoi, in the present study, is an advance regarding the elucidation of the mechanisms involved in the host selection behavior of this species.

“…However, Manoj and Sofian-Azirun (2002) found only sensilla chaetica (ch) on the scape and pedicel of B. caraznbolae. Trichoid sensillae function as a mechano-receptors in numerous insects, as stated by Fernandes et al (2002) for Dermatobia hominis, by Merivee et al (2002) for Bembidion properans, by Renthal et al (2003) for Solenpsis invicta, and by Ochieng et al (2000) for Microplitis croceipes.…”

“…Insect's antennae have various types of sensilla with different functions that play important roles in various behaviors during adult life. Antennal sensillae are important sensory receptors used in host location and discrimination behaviors (Schneider1964; Ochieng et al 2000). The antenna is the major channel of sensory input, including receptors for volatile odors and pheromones, contact chemoreception, water vapor, carbon dioxide, sound perception, and touch (Ehmer and Gronenberg 1997;Renthal et.…”
