Abstract Fruit flies (Diptera: Tephritidae) are the most damaging pests on fruit crops Réunion Island, near Madagascar. Survival and development of Mediterranean fly, Ceratitis capitata (Wiedemann), Natal C. rosa Karsch Mascarenes catoirii Guérin-Mèneville were compared at five constant temperatures spanning 15 to 35°C. Durations immature stages , C ranged from 14.5–63.8, 18.8–65.7 16.8–65.8 days, respectively, 30–15°C. The lower developmental threshold thermal calculated using temperature...

Abstract The ‘ Ceratitis FAR complex’ is a species complex of African fruit flies (Diptera, Tephritidae) including the major agricultural pest C eratitis rosa and morphologically similar fasciventris anonae . To resolve their intra‐ interspecific genetic relationships to estimate gene flow within this complex, we surveyed allelic variation at 16 microsatellite loci in 27 populations three morphospecies. Interpopulation distances individual Bayesian assignments distinguished five genotypic...
Since it first appeared in the New World 2004, palm red mite, Raoiella indica Hirst, has spread to many countries, from Florida (USA) northern part of Brazil. In this region, mite been recorded on several different hosts, but most harmful coconut. For reasons, chemical control pest is not feasible, and biological considered an important measure be pursued. The objective paper provide details about effort determine potential natural enemies R. La Reunion, for their possible introduction only...
A set of 10 microsatellite markers was used to survey the levels genetic variability and analyse aspects population dynamics two potentially invasive pest fruit fly species, Ceratitis rosa C. fasciventris, in Africa. The loci were derived from closely related capitata. degree polymorphism fasciventris extensive comparable that In rosa, evolution its distribution area reflects colonization history this species. mainland populations are more polymorphic than island populations.

Climatic conditions and the physiological state of a parasitoid may alter its host selection behavior thus efficiency as biological control agent. We studied influence these parameters on Fopius arisanus (Sonan), an egg-pupal many Tephritidae. In first experiment, we assessed in field cage assays temperature, humidity, light intensity, barometric pressure, wind speed. Both flight parasitism were mainly affected by temperature humidity. However, because two factors strongly correlated our...
Abstract In recent years, the coconut whitefly, Aleurotrachelus atratus Hempel, has been recorded from various islands in southwestern Indian Ocean. Field surveys La Réunion, Seychelles, Comoros and glasshouses Paris have allowed us to record this whitefly on 56 palm species, some of which are endemic and/or threatened species. Most trees showed low infestation levels, except for that is its main host plant. Such a wide range facilitated rapid geographical dissemination whitefly. A field...
The objective of the study was to compare courtship behavior various wild and mass reared medfly strains, in order document degree diversity among populations assess its implications for strategy application Sterile Insect Technique. Recordings were collected from several locations world-wide using a standard protocol. Qualitative quantitative analysis behavioral materials conducted. No major differences found strains both male female repertoire, which indicates general lack incompatibility...
Abstract The males of some fruit flies ( D iptera: T ephritidae) are known to be attracted specific parapheromones. trapping results between trimedlure TML ) and enriched ginger root oil EGO lure) were compared at two experimental sites in M orogoro C entral anzania) for a period 12 weeks co‐inciding with the main citrus season. Both attractants captured comparable diversity flies, except that lure also such as Ceratitis cosyra , not normally found ‐baited traps. mainly or exclusively male...

To select efficient baits to attract fruit flies (Diptera: Tephritidae), the use of field cages represents a good compromise between laboratory and outdoor studies. Nevertheless, methodological details such experiments up now have had little attention. assess influence intrinsic extrinsic factors on efficiency food attractants for Bactrocera cucurbitae (Coquillett), series were conducted in with McPhail traps.
