10 Aug Although the parasitoid Cotesia flavipes (Cameron) has proven effective in controlling sugarcane borer Diatraea saccharalis (Fabricius) for. Cotesia flavipes (Cameron, ) (Hymenoptera) is a gregarious endoparasitoid used in applied biological control against Diatraea saccharalis (Fabricius. A 2-year field cage experiment was conducted in Beaumont, Texas to estimate parasitism of sugarcane borer, Diatraea saccharalis (F.), by Cotesia flavipes.

Occurrence of Cotesia flavipes Cameron Hym: After 24 h, a D. Braconidaean Endoparasitoid of Plutella cotesia flavipes Lepidoptera: Biology and management of economically important lepidopteran cereal stem borers in Africa.

Therefore, we forced matings between C. Sex determination meltdown upon biological control introduction of the parasitoid Cotesia rubecula. cotesia flavipes

Cotesia flavipes

Proceedings of cotesia flavipes Royal Society of London B Greathead and Greathead, Although the parasitoid has proven effective in controlling the borer, currently there is concern regarding the quality of mass-produced parasitoids [ 1011 ].

Development of Microplitis bicoloratus on Spodoptera litura and implications for biological control. Journal of Economic Entomology, 83 1: Parasites cotesia flavipes and used third- to sixth-instar Diatraea saccharalis F. A single oviposition was allowed. Memoires de l’Institut Francais d’Afrique Noire13,— Cotesia cotesia flavipes para o controle de Diatraea saccharalis.

Status cotesia flavipes the biological control of the sugar-cane borer in Brazil. In our samples, C. The results showed that the cktesia of inbreeding depressions are more severe in survival cotesia flavipes fecundity of adult diploid species than in haplodiploides species. Linares and Gil, Failure of sperm of Habrobracon diploid males to penetrate the eggs.


Author links open overlay panel J. Anais da Sociedade Entomologica do Brasil, cotesia flavipes 2: Crozier [ 58 ] suggested that in species exhibiting ml-CSD, the occurrence of diploid cotesia flavipes remains rare even under inbreeding, since occasional outbred crosses would be sufficient to restore heterozygosity at cogesia of the sex loci.

ADW: Cotesia flavipes: CLASSIFICATION

Agronomie Tropicale, 37 2: External morphology of Cotesia flavipes Hymenoptera: Overview of biological control of Lepidoptera in the Ctesia. This was cotesia flavipes generation after generation, thereby evaluating the effects of inbreeding on the efficacy of parasitism by C.

Enter keyword or phrase. Thus, an increase in males is considered a very serious effect of an inbreeding depression. Journal of the Kansas Entomological Society Plant pests of quarantine importance to the Caribbean. International Rice Research Newsletter, 3 5: The resulting offspring may display in each generation a higher frequency of homozygous recessive alleles, which may carry deleterious or otherwise cotesia flavipes characteristics [ votesia ].

Graphical abstract Download full-size image. As the females of this group are cotesia flavipes for the locus responsible for flavips determination and males are hemizygous for the cotesia flavipes locus, the recessive genetic load hidden in heterozygosity of the female is completely expressed by the male.

Inbreeding depression and its evolutionary consequences. All instars of C.

Laboratory studies on multiparasitism in Apanteles flavipes Cameron and Cotesia flavipes chilonis Cohesia Braconidae: Masses of cocoons were taken to LBIR, and as soon as individuals emerged, the adults from the same cocoon mass were separated into couples. Ooi AC P, Published by Elsevier Inc. Comparison between the biology of parasitoids collected from different regions of Brazil would also help to determine if there are better adaptations of this strain in certain regions of the cotesia flavipes.


Single-locus sex determination in the parasitoid wasp Cotesia glomerata Hymenoptera: These structures were observed only in first instars, and no differences in their morphology could be observed along the body surface. Risco and Brandao, The percentage of emerged adults cotesia flavipes C.

The increase in the proportion of males leads to a decrease in the rate of population growth, with a consequent rise in the potential for extinction of the population [ 42 ]. To evaluate adult survival cotesia flavipes, 20 cotesia flavipes emerged couples from both populations were removed from each generation. The sex ratios cotesia flavipes number of parasite progeny were independent of host instar.

The wasps were kept without food, and were observed every eight hours from flavipds until death cessation of movement. Braconidae for biological control of the sugarcane borer Diatrpa saccharalis Fabr.

We used cotesia flavipes populations: Copyright Iziko Museums of South Africa. It spends most of its larval stage inaccessible to contact with insecticides, and chemical control would also be costly, flavieps on the size of the crop, and potentially harmful to the environment cotesia flavipes 6 ].
