“…The response of male Trichoplusia ni to its female sex pheromone, for example, has been shown to depend on the light intensity, time of day and the age of the male moths (Shorey & Gaston, 1964,1965Shorey et al, 1968). Similarly, the response of male Trogoderma granarium to the female sex pheromone is affected by their sexual status, decreasing by about 50% after mating (Adeesan et al, 1969). In Oryzaephilur surinamensis (L.) Correspondence: Dr Peter White, Department of Zoology, South Parks Road, Oxford OX1 3PS.…”

ABSTRACT. The effects of insect age, sex, mated state and culture density on the attraction of adult saw‐toothed grain beetles, Oryzaephilus surinamensis (L.) (Coleoptera: Silvanidae), to sources of food odour and synthetic aggregation pheromone were investigated. In single‐insect behavioural assays, insect age affected the attraction to the food odour, but not to the synthetic aggregation pheromone. Conversely, there were sexual differences in the attraction to the aggregation pheromone, but not to the food odour. The effects of the same factors on the antennal response to food odour and synthetic pheromone were also investigated, using the electroantennogram (EAG) technique. Insect age affected the EAG response to food odour, but not to the synthetic pheromone. There were no sexual differences in the EAG responses to either food odour or synthetic pheromone. The correlation of factors affecting both behavioural and antennal responses, and the possible role of changes in peripheral olfactory receptor sensitivity in the modulation of behaviour are discussed.

“…There are no earlier reports of H. armigera females showing EAG response to pheromone blends. However, the response of unmated males to pheromone blends has been well documented in earlier studies 24 . Autodetection was earlier reported from other moths such as Panaxia quadripunctaria 14 , Choristoneura rosaceana 25 and Grapholitha molesta (Busck) 26 .…”

Autodetection in <i>Helicoverpa armigera</i> (Hubner)

Autodetection is an olfactory behavioural process where the females of some species respond to their own pheromonal blends. Through electroantennogram studies it has been proved that the gravid females of Helicoverpa armigera (Hubner) respond to their pheromone blend consisting of Z-11-hexadecenal and Z-9-hexadecenal in the ratio 97 : 3. Male antennae respond more strongly than virgin female antennae. However, antennae of gravid females elicit strong response than unmated males. Also, males showed strong responses in cross-wind flying in wind tunnel experiments, when sex pheromone blends were used. Virgin females and gravid females showed poor response in wind-tunnel studies. The ovipositional experiment where gravid females were allowed to oviposit in the presence and absence of pheromone odours indicated that there was no difference in the number of eggs laid. Through morphological studies, it has been proved that the females also possess sensilla trichoidea, destined to perceive the pheromone blends, though lesser in number than the males. These results support the hypothesis that autodetection of sex pheromones exists in females of H. armigera and is thought to function as a mechanism to induce dispersal under high population densities.

“…The khapra beetle (Trogoderma granarium Everts) is a serious pest, mainly of stored cereals. The olfactory responses of the adults to the odours of whea~ and faecal components were reported by Stanid & Shulov (1969), and to the pheromones by Finger (Bar/dan) et al (1965); Yinon & Shulov (1967); Levinson & Bar Ilan (1967;1969) and Adeesan et al (1969).…”

Brief extraction of the virgin females of Trogoderma granarium yielded a mixture of fatty acids, the major ones being palmitic and oleic acids; these were accompanied by minor quantities of linoleic, palmitoleic, margaric and stearic acids. The aggregation effect of these cuticular fatty acids on the females of Trogoderma granarium is recorded. Résumé RÉPONSE DES FEMELLES DE TROGODERMA GRANARIUM (COLEOPTERA DERMESTIDAE) AUX ACIDES GRAS LIBRES CUTICULAIRES Des femelles vierges de Trogoderma granarium sont soumises à une extraction rapide en vue d'obtenir seulement les lipides de la surface cuticulaire. On obtient un mélange d'acides gras dont les plus importants sont les acides palmitique et oléique, accompagnés de petites quantités d'acides linoléique, palmitoléique, margarique et stéarique. Ces divers acides gras cuticulaires ont un effet attractif plus ou moins marqué sur les femelles de Trogoderma.
