Acceptability and Suitability of Three Liriomyza Species as Host for the Endoparasitoid Halticoptera arduine (Hymenoptera: Pteromalidae).

In the scope of using Halticoptera arduine (Walker; Hymenoptera: Pteromalidae) in a classical biological control program in East Africa, laboratory bioassays were conducted to evaluate the acceptability and suitability of the three economically important Liriomyza leafminer species to the exotic parasitoid. Searching time, number of oviposition attempts, F1 parasitoid developmental period, parasitism rates, sex ratio, host mortality, and body size indices were assessed. H.

Interaction Between Two Leafminer Parasitoids, Halticoptera arduine (Hymenoptera: Pteromalidae) and Diglyphus isaea (Hymenoptera: Eulophidae), in the Management of Liriomyza huidobrensis (Diptera: Agromyzidae).

Liriomyza spp., leafminer flies (Mik; Diptera: Agromyzidae), are economically important quarantine pests that puncture and mine leaves and fruits of various horticultural crops worldwide, affecting yield and trade. Halticoptera arduine (Walker; Hymenoptera: Pteromalidae), a key parasitoid from the pests' areas of origin in South America, was introduced as a potential alternative management strategy.

Acceptability and Suitability of Three Liriomyza Leafminer Species as Host for the Endoparasitoid Chrysocharis flacilla (Hymenoptera: Eulophidae).

Liriomyza leafminers represent important threats to the horticulture sector in East Africa. Parasitism rates of local parasitoids are reported to be low and the endoparasitoid, Chrysocharis flacilla (Walker) (Hymenoptera: Eulophidae), was introduced in Kenya for a classical biological control program. Acceptability and suitability bioassays were conducted on the three economically important Liriomyza species in Africa (Liriomyza huidobrensis (Blanchard) (Diptera: Agromyzidae), Liriomyza sativae (Blanchard) (Diptera: Agromyzidae), and Liriomyza trifolii (Burgess) (Diptera: Agromyzidae).

Interaction Between Chrysocharis flacilla and Diglyphus isaea (Hymenoptera: Eulophidae), Two Parasitoids of Liriomyza Leafminers.

Agromyzid Liriomyza leafminer flies are a major threat to horticultural production in East Africa with low natural control reported. The endoparasitoid Chrysocharis flacilla (Walker; Hymenoptera: Eulophidae) was introduced from Peru into quarantine facilities at ICIPE in Kenya for a leafminer classical biological control program. Interaction assays with one of the dominant local parasitoids, Diglyphus isaea (Walker; Hymenoptera: Eulophidae), using Liriomyza huidobrensis (Blanchard; Diptera: Agromyzidae) was assessed through sole, simultaneous and sequential releases.
