Geographic distribution and ecology of two species of Orsillus (Hemiptera: Lygaeidae) associated with cones of native and introduced Cupressaceae in Europe and the Mediterranean Basin Inra
Rouault, G.; Cantini, R.; Battisti, A.; Roques, A..
Dans le Bassin Méditerranéen, deux punaises des graines du genre Orsillus Dallas, O. maculatus Fieber et O. depressus Mulsant et Rey, se partagent l'exploitation des cônes de Cupressacées pour leur nutrition et leur reproduction. Ces deux espèces transportent les spores d'un champignon pathogène, Seiridium cardinale Sutton & Gibson, responsable de la maladie du chancre cortical du cyprès. Le cycle biologique respectif des deux espèces est comparé. L'analyse de 89 récoltes de cônes réalisées dans 10 pays méditerranéens a confirmé que O. maculatus est plus étroitement associée à Cupressus sempervirens L. bien qu'elle puisse aussi se retrouver sur d'autres espèces de Cyprès et, mais plus rarement, de Chamaecyparis Spach. Orsillus depressus semble plus...

Oviposition sites of the cypress seed bug Orsillus maculatus and response of the egg parasitoid Telenomus gr. floridanus Inra
Rouault, G.; Battisti, A.; Roques, A..
Phytophagous insects have many strategies to escape parasitoids, for example by hiding eggs into plant tissues, but oviposition in holes made by another insect is rather scarce. The cypress seed bug Orsillus maculatus Fieber (Heteroptera: Lygaeidae) is strictly dependent on the availability of cones of Cupressus sempervirens L. to oviposit. Females lay eggs either in exit holes cut through the cone scale by emerging adults of the cypress seed chalcid, Megastigmus wachtli Seitner (Hymenoptera: Torymidae), or on the inner side of scales of partly open cones. A recently discovered egg parasitoid belonging to the genus Telenomus has been shown to attack bug eggs in both oviposition sites. In this paper we investigated the parasitoid performance according to...

Potential invasion of China by exotic insect pests associated with tree seeds Inra
Roques, A.; Sun, J.H.; Auger-Rozenberg, M.A.; Hua, O..
A total of 39 insect species, mostly seed chalcids in the genus Megastigmus (Hymenoptera), but also midges (Diptera), are listed as potential seed-borne invaders of Chinese conifers. Although the number of native seed insects per conifer genus does not differ between China and other biogeographical regions, there are significantly fewer seed insects associated with each conifer genus in China than potential invaders. The eventual success of the invaders is likely to depend on the presence of native Chinese conifers that are congeneric with the original host, or on the presence of the original host as an exotic. When a substantial entomofauna is already associated with cones, competition for seed resources may limit the potential impact of invaders because...
