The Ovipositional Behavior in Euplectrus kuwanae CRAWFORD (Hymenoptera : Eulophidae), a Parasitoid of Argyrogramma albostriate (BREMER et GREY) : Lepidoptera : Noctuidae

Neochrysocharis formosa (Westwood) (Hymenoptera: Eulophidae), a newly recorded parasitoid of the tomato moth, Tuta absoluta (Meyrick) (Lepidoptera: Gelechiidae), in Argentina.

We report the first record of Neochrysocharis formosa (Westwood) parasitizing larvae of the tomato moth, Tuta absoluta (Meyrick), in tomato crops in Northern Buenos Aires Province, Argentina. Tomato moth larvae were sampled during four consecutive growing cycles, between 2003 and 2005, in 10 sites. Neochrysocharis formosa was present only in organic outdoor and protected crops, and predominantl...

The preimaginal stages of Pnigalio gyamiensis Myartseva & Kurashev, 1990 (Hymenoptera, Eulophidae), a parasitoid associated with Chrysoesthia sexguttella (Thunberg) (Lepidoptera, Gelechiidae)

The larval instars of Pnigalio gyamiensis Myartseva and Kurashev are described in detail for the first time. This species is a larval-pupal ectoparasitoid of Chrysoesthia sexguttella (Thunberg) (Lepidoptera, Gelechiidae), which forms leaf mines in the plant Chenopodium album L. (Caryophyllales: Amaranthaceae). The female of Pnigalio gyamiensis lays a single egg on the skin of the host larva or ...
