Les auteurs relatent l'elevage et la multiplication de cinq hymenopteres parasites, leur liberation dans les cultures de mais et les resultats de ces essais. De 1981 a 1983, 2,8 millions de Tetrastichus atriclavus, 6,3 millions de Trichospilus diatraeae, 411000 Apanteles flavipes, 100000 Trichogramma confusum, 112000 T. evanescens et 834000 T. nagarkatii ont ete liberes. Malgre les precautions prises pour assurer la qualite du transport, pour garantir le bon etat des insectes au moment de leur… 
Relationships betweenApanteles flavipes (Hym.: Braconidae) andNosema bordati (Microspora,Nosematidae) parasites ofChilo partellus (Lep.: Pyralidae)
N. bordati is highly pathogenic to the immature instars of the parasitoid and lightly infected adults of A. flavipes are able to transmit the Microsporidian.
Novo registro de Trichospilus diatraeae Cherian & Margabandhu, 1942 (Hymenoptera: Eulophidae), como parasitóide de Spodoptera cosmioides Walker, 1858 (Lepidoptera: Noctuidae) no Brasil
This is the first report of T. diatraeae parasitizing pupae of S. cosmioides, parasitoid, and offers new prospects for biological control programs.
Capacidade reprodutiva de Trichospilus diatraeae (Hymenoptera: Eulophidae) em pupas de diferentes hospedeiros (Lepidoptera)
The reproductive capacity of the endoparasitoid Trichospilus diatraeae Cherian & Margabandhu, 1942 (Hym.: Eulophidae) on lepidopteran host pupae was dealt with, with significant difference in the progeny emergence.
Parasitization of Selected African Stemborers By Cotesia Flavipes Cameron and Cotesia Sesamiae (Cameron) (Hymenoptera:Braconidae) with Emphasis on Host Selection and Host Suitability.
This work investigated the host and host habitat location, the acceptability and suitability of Chilo partellus and indigenous stemborer hosts for the development of Cotesia flavipes and a local natural enemy, Coteia sesamiae (Cameron) (Hymenoptera: Braconidae), as well as the semiochemicals involved in host finding.
Evaluation of Trichospilus diatraeae (Hymenoptera: Eulophidae) as parasitoid of the eucalyptus defoliator Euselasia eucerus (Lepidoptera: Riodinidae)
This report reports the first report of T. diatraeae parasitizing pupae of the eucalyptus defoliator Euselasia eucerus Hewitson in Brazil, a gregarious pupal parasitoid that preferentially attacks species of the order Lepidoptera.
Primer reporte de Trichospilus diatraeae (Hymenoptera: Eulophidae) parasitando pupas de lagarta Hypsipyla grandella, principal plaga forestal en America Latina y el Caribe, abriendo nuevas
Preparedness for borer incursion : SRDC final project report BSS249
Data from two mitochondrial genes COII and 16S were used to construct a molecular phylogeny including 26 species from 10 genera and 6 tribes, suggesting a robust taxonomy within this subfamily of Lepidoptera and supporting the separation of the Pyralidae and Crambinae.
Evolutionary and Applied Aspects of the Behavioural Ecology of the Stemborer Parasitoid Cotesia flavipes
Several aspects of the host foraging behaviour on C. flavipes are discussed in relation to the ecology of the parasitoid, such as the role of learning in foraging and clutch size allocation decisions, and to what extent the reported plant and host specificity is due to phenotypic plasticity through learning.
Biology and management of economically important lepidopteran cereal stem borers in Africa.
The status of knowledge about economically important cereal stem borers in Africa is summarized with emphasis on their distribution, pest status and yield losses, diapause, natural enemies, cultural control, host plant resistance, and biological control.
