“…VI and V2 are rigid, elongated, and overlap forming a lumen that allows the passage of eggs and secretion from the poi son glands through movements generated by the sliding of these valves (Brown & Anderson, 1998). The host's move could result in wasted time and energy invested by the parasitoid in parasitism; because this is a complex process, it is essential to the parasitoid to be precise in its onslaught against the host.…”

Parasitoid-host interaction: sensory structures involved in the parasitism behavior of Bracon vulgaris (Hymenoptera: Braconidae)

et al. 2014

Parasitoids have evolved mechanisms to evade their hosts' defenses. Bracon vulgaris (Ashmead) is a larval ectoparasitoid responsible for natural reduction of Anthonomus grandis (Boheman) and Pectinophora gossypiella (Saunders), which are considered the main cotton pests in the cotton agro ecosystem in northeastern Brazil. This study aimed to analyze the sensory structures (antennae and ovipositor) involved in the parasitism behavior of B. vulgaris, and to describe and evaluate associations between composition, morphology, and functions of these structures in the parasitoid-host interaction. Results showed that the B. vulgaris ovipositor is a multifunctional structure of 2.7 ± 0.3 mm in length composed of 3 valves. Valves 1 and 2 are elongated, rigid, and act jointly to pierce the host's cuti cle, to inject the poison glands secretion, and to deposit eggs. Valve 3 covers the other valves, giving them protection. Valve 3 also presents annulations in all its extension, which gives flexibility to the ovipositor, and trichoid sensilla that possibly capture vibrations from the host's feeding and loco motion, thereby aiding the parasite in the host selection. The presence of cuticular microtrichia was possibly responsible for the cleaning of the ovipositor, keeping it functional between the various inser tions that occur during the parasitism behavior. The parasitoid's antennae are filliform-like, measure about 2 mm, and are composed of four types of sensilla (trichoids, basiconical, coeloconical, and pla codes) that act as olfactory and gustatory receptors and/or express tactile, thermo,-and hygroreception functions. The integrated action of these sensory components corroborates the successful parasitism behavior of the parasitoid B. vulgaris.

“…Thus, we conclude that Ba.6 located on the ovipositors of C. caragana function as gustatory sensilla and are sensitive to chemical cues from substances such as salts, water and amino acids (Zacharuk, 1985). Studies of the sensilla basiconica on the ovipositor of Trybliographa rapae Westwood (Cynipoidea: Figitidae) show that a dendrite with a mechanical sensing function is involved in regulating the stretching of the matrix in the ovipositors (Brown and Anderson, 1998). Sensilla basiconica I, II and III without buds, and sensillum coeloconicum in P. recurva are similar to Ba.7, and may be sensitive to temperature and humidity (Faucheux, 2012).…”

“…O fato de o ovipositor geralmente ser recoberto por quimioreceptores faz com que sua rápida inserção no corpo da lagarta hospedeira seja suficiente para que a fêmea a aceite ou a rejeite, podendo inclusive verificar se o seu hospedeiro já foi parasitado e qual é o seu valor nutritivo no momento da postura, por meio de pistas bioquímicas, controlando, portanto, a sua alocação sexual (Godfray 1994, Brown & Anderson 1998. A seleção feita pela fêmea é baseada no equilíbrio entre qualidade e quantidade de suprimento alimentar para sua progênie que a fêmea consegue perceber quando entra em contato com o hospedeiro (Vinson & Iwantsch 1980).…”

Host Preference of Apanteles galleriae Wilkinson (Hymenoptera: Braconidae) for Galleria mellonella (L.) or Achroia grisella (Fabricius) (Lepidoptera: Pyralidae)ABSTRACT -Caterpillars of Galleria mellonella (L.) and Achroia grisella (Fabricius), considered pests of beehives, were used to test host preference of the parasitoid Apanteles galleriae Wilkinson. On average, A. galleriae females originated from a lab rearing on both hosts preferred to parasitize caterpillars of A. grisella in 67% of the tests. The same experiment was repeated using A. galleriae females that had been reared during five generations in each of the host species, with similar results. A. galleriae females reared in caterpillars of G. mellonella parasitized A. grisella caterpillars in 64% of the tests, whereas the A. galleriae females reared in A. grisella parasitized the same species in 63.5% of the tests. This preference was not dependent on the number of host caterpillars used in each test. We conclude that A. grisella is a better host than G. mellonella to rear A. galleriae under laboratory conditions, and that the parasitoid is a promising natural enemy for the biological control of these species of wax moths because it can be easily reared in both species and none of these hosts show resistance to the parasitoid.
