Abstract

This paper reports observations made on the sensory biology of Chilo partellus larvae and adults. The larval and adult antennae of this insect have hygro/thermosensitive sensilla equipped with receptor cells sensitive to minute changes in temperature. Inputs through those cells may partly be responsible for the light evasive and other light/temperature-dependent behaviour patterns. The grooved basiconic sensilla especially those found on the male antennae are sensitive to the female sex pheromone components of C. partellus. Host-plant odours are most likely perceived by one or two of the other antennal olfactory sensilla, namely the smooth-surfaced basiconica and coeloconica sensilla. Chilo partellus moths have a limited number of gustatory sensilla on the tarsi, ovipositor, antennae and the proboscis. Electrophysiological bioassays done on the ovipositor and tarsal sensilla are discussed. Similar tests on the larval maxillary styloconica sensilla showed that the lateral and medial sensilla differed in their sensitivity. Their taste receptor cells can detect differences between saps from susceptible and resistant host-plants.

Résumé

Cette publication est basée sur certaines observations faites sur la biologie sensorielle des larves et adultes de Chilo partellus. Les antennes de larves et adultes de Chilo partellus ont des sensilles hygro-thermosensibles équipées de cellules receptrices qui enregistrent les changements dues à la temperature. L'énergie provenant de ces cellules peuvent partiellement être responsable du phéromène evasif à la lumière et autres facteurs dépendant de lumière-temperature. Les sensilles basiconiques specialement ceux qu'on trouve sur les antennes des mâles sont sensible à l'effet des phéromones sexuels de Chilo partellus. Les odeurs des plantes-hôtes sont apercues soit par un ou deux types de sensilles olfactrices de l'antenne appelées sensilles basiconiques ayant une surface lisse et les sensilles coeloconiques. Les adultes de C. partellus ont un nombre limité de sensilles gustatrices sur les tarses, les ovipositeurs, les antennes et le proboscis. Les données electrophysiologiques des essais biologiques faits sur les sensilles des tarses et de l'ovipositeur ont été discutées. Des epreuves similaires faites sur les sensilles styloconiques des larves ont montré que les sensilles laterales et medianes diffèrent de leur sensibilité et que les cellules receptrices peuvent detecter les differences entre les plantes-hôtes resistantes et susceptibles.
