Abstract

Larval parasitism of the sorghum shoot fly, Atherigona soccata Rondani (Diptera: Muscidae), by Neotrichoporoides nyemitawus Rohwer (Hymenoptera: Eulophidae) was studied in the laboratory. Ten shoot fly larvae of each instar (3) and two periods of exposure (24, 48 h) were used in a factorial design with four replicates. Significant differences of parasitism were observed with respect to instars, periods of exposure, and the interaction instar-period of exposure. The second larval instar was most parasitized (68.75 and 85% of parasitism after 24 and 48 h, respectively), followed by the first instar (46.25% of parasitism) exposed for 48 h to adult parasitoids. N. nyemitawus was an effective shoot fly endo-larval parasitoid. Observations on N. nyemitawus searching sorghum seedlings for shoot fly larvae are summarized.

Résumé

Le parasitisme larvaire de la mouche des pousses du sorgho, Atherigona soccata Rondani (Diptera: Muscidae), par Neotrichoporoides nyemitawus Rohwer (Hymenoptera: Eulophidae) a été étudié au laboratoire. Dix larves de chaque stade larvaire de la mouche et deux temps d'exposition (24, 48 h) ont été utilisés dans un dispositif factoriel en quatre répétitions. Des différences significatives ont été observés entre les stades larvaires de la mouche, les temps d'exposition et I'interaction stade larvaire-temps d'exposition. Les stades larvaires les plus parasites ont été Ie deuxième (68,75 et 85% de parasitisme respectivement après 24 et 48 h) suivi du premier après 48 h d'exposition (46, 25% de parasitisme). N. nyemitawus a été un endoparasitoïide larvaire efficace. Le comportement d'attaque de N. nyemitawus est succintement décrit.
