Cotesia is a genus of Braconid wasps. Some species parasitize caterpillars of species considered as pests. Thus they are used as biocontrol agents. Cotesia. — Florida Entomologist — Volume , No. 4.

Entomological problems in Bolivia. PloS ONE ; 8: Mating and oviposition behaviour in two Apanteles species. Individual females were then allowed to parasitize larvae of D.
Lepidoptera in the Punjab. Braconidae using Diatraea saccharalis Lepidoptera: Comparative biology and ecology of Apanteles flavipes Cam. Braconidaea parasite of Chilo sp. Sl-CSD species often have mechanisms to prevent the occurrence of mating between relatives [ 48 ]. Considering all the mechanisms that can cause a loss in variability, inbreeding appears to be the most relevant to established colonies in laboratories [ 1415 ]. Cambridge University Press; Distribution Table Top of page The distribution in this summary table is based on all the information available.

citesia The Cotesia flavipes species-complex: Galleries formed within the stem weaken the plant, making it easier to fall, and eventually can lead to death or breakage, a symptom known as “dead heart” [ 5 ].
Insect parasites of borers of Graminaceae in Madagascar. This work highlights the need to conduct further studies seeking to ascertain through molecular analysis whether there has indeed been a loss in genetic variability of the introduced strain.
Flavipds ability for damage is compounded by the frequency with which it occurs in the cane fields, its high biotic potential, and the favorable climate in Brazil [ 4 ]. To assure inbreeding, newly ctesia females were forced to mate with a sibling.

Inbreeding depression and its evolutionary consequences. However, its effects can be measured mainly by characteristics limited to females, such as fecundity, looking for hosts, and determining the sex ratio of offspring [ 2326 ]. Insecta Natural enemy of Diatraea grandiosella Helicoverpa armigera Ostrinia nubilalis Scirpophaga incertulas Sesamia calamistis. After 24 h, a D. After forty years since the beginning of the biological control program with C.
Support Center Support Center. Inbreeding in a natural population of the gragarious parasitoid wasp Cotesia glomerata. Ecological considerations of the introduction of Cotesia flavipes Cameron Hymenoptera: Therefore, even with the difficulties, this study should be conducted in the near future.
We used two populations: References Top of page Alam MM, Environmental Entomology, 19 6: We wanted to determine what happened to the quality of the parasitoid after 10 generations in an extreme inbreeding situation. Elevege plusiers especes du genre Chilo et de certains de leurs parasites pour la lutte biologique contre les foreurs des graminees en Afrique.
They were maintained under the same conditions of temperature, photoperiod, and relative humidity as the test subjects. SAS Institute Inc; Linares B; Gil GY, Male production can increase significantly after successive consanguineous matings as a result of the action of inbreeding on the mechanism of sex determination of the species.
