Antennal pathways in the central nervous system of a blood-sucking bug, Rhodnius prolixus Inra
Barrozo, R.B.; Couton, L.; Lazzari, C.R.; Insauti, T.C.; Minoli, S.A.; Fresquet, N.; Rospars, J.P.; Anton, S..
The haematophagous bug Rhodnius prolixus has been a model system in insect physiology for a long time. Recently, several studies have been devoted to its sensory systems, including olfaction. However, few data are available on the basic organisation of the nervous system in this species. By means of neuronal backfills, histology, confocal microscopy and three-dimensional reconstruction methods, we have characterized the projection patterns of antennal sensory neurons within the central nervous system of this disease-vector insect. We established the first partial three-dimensional map of the antennal lobe (AL) of a hemipteran insect. The ALs of this species are relatively diffuse structures, which nevertheless show a glomerular organisation. Based on...

Bisabolene epoxides in sex pheromone in Nezara viridula (L.) (Heteroptera: Pentatomidae): role of cis isomer and relation to specificity of pheromone Inra
Brezot, P.; Malosse, C.; Mori, K.; Renou, M..
The trans- andcis-(Z)-α-bisabolene epoxides (trans- andcis-(Z)-αBE) are the main components of the male sex pheromone in Nezara viridula. The role of thecis isomer and the importance of thecis/trans proportion for the activity and the specificity of the pheromone are not clearly elucidated and were studied here. Interindividual variation of thecis/ trans proportion produced by males was studied by individual hexanic extracts in two strains originating from the south of France (SF) and French West Indies (FWI). The trans isomer composed 42–82% of bisabolene epoxides in SF males and 74–94% of bisabolene epoxides in FWI males. Means (± SD) significantly differ between SF (62.8%±8.4) and FWI (82.4%±5.9) males in spite of this interindividual variation....

Chemistry of defensive secretions in nymphs and adults of fire bug , Pyrrhocoris apterus L.(Heteroptera, Pyrrhocoridae) Inra
Farine, J.P.; Bonnard, O.; Brossut, R.; Le Quere, J.L..
The defensive secretions from the nymphs and the adults of both sexes in P. apterus were chemically investigated. Forty components were identified from the nymphal posterior dorsoabdominal glands and 35 from the adult metathoracic glands of both sexes. Within the 43 identified chemicals, we found 23 aldehydes, five saturated hydrocarbons, five alcohols, three ketones, three lactones, two terpenes, one phenol and one ester. Thirteen of these compounds had never been reported within the Heteroptera. Whereas eight components are specific to the nymphs, methyl pentenal, (E)-2-hexenol, and heptadecanal are the only adult-specific components. The biological role of all the identified chemicals is almost unknown in P. apterus and is discussed comparatively with...

Chemistry of pheromonal and defensive secretions in the nymphs and the adults of Dysdercus cingulatus fabr. (Heteroptera, Pyrrhocoridae) Inra
Farine, J.P.; Bonnard, O.; Brossut, R.; Le Quere, J.L..
The exocrine secretions from the nymphs and the adults of both sexes in D. cingulatus were chemically investigated. Seven compounds were identified in the anterior glands, and eleven in the median dorsoabdominal glands of nymphs and adults of both sexes. Fifty-five compounds were identified in the defensive glands (34 in posterior dorsoabdominal glands ofnymphs and 21 in metathoracic glands of adults), and six in the sternal glandular epithelium of the males. The biological function of the glandular secretions and of their identified compounds were investigated and are discussed.

Dorsal abdominal glands in nymphs of southern green stink bug, Nezara viridula (L.) (Heteroptera: Pentatomidae): chemistry of secretions of five instars and role of (E)-4-oxo-2-decenal, compound specific to first instars Inra
Pavis, C.; Malosse, C.; Ducrot, P.H.; Descoins, C..
We investigated the exocrine secretions from the five nymphal instars in the southern green stink bug, Nezara viridula, by analyzing separately the contents of the three dorsal abdominal reservoirs. All DAGs 1 produced a mixture of five alkanes with 12, 13, 14, 15, and 16 carbons. No differences were found between DAGs 2 and DAGs 3, for the five instars: the glands of first instars produce the same alkanes as DAGs 1, n-tridecane, traces of (E)-2-decenal, and a specific compound: (E)-4-oxo-2-decenal. In the other instars (second to fifth), (E)-4-oxo-2-decenal is absent from the secretion but another compound is present: (E)-4-oxo-2-hexenal. The kinetics of production of the different compounds were studied, the maximum amounts produced occurring 36 hr after...

Etude de l’évolution des insectes auxiliaires et de leurs relations avec le psylle du poirier (Psylla pyri L.) et l’acarien rouge (Panonychus ulmi Koch) dans deux vergers du Sud-Est de la France en 1979 Inra
Fauvel, G.; Atger, P..
Une étude de la répartition spatiale et de l’évolution temporelle du psylle du poirier, de l’acarien rouge et des principaux auxiliaires a été conduite par battage et contrôle visuel dans deux vergers de poirier du Sud-Est de la France en 1979. Elle montre que, vis-à-vis de Psylla pyri L., Anthocoris nemoralis F. manifeste la meilleure corrélation et la réponse numérique la plus nette. Les Orius et Orthotylus nassatus F. se montrent plus nettement liés à Panonychus ulmi Koch tandis que l’évolution des araignées traduit leur polyphagie et suit d’une manière assez marquée celle des thrips. Un arrosage violent par aspersion perturbe beaucoup plus le développement des auxiliaires que celui du psylle et les anthocorides ont semblé plus sensibles que les...
