Trichogramma(Hymenoptera: Trichogrammatidae) Species, Egg Parasitoids ofDiatraea saccharalis(Lepidoptera: Crambidae) on Sugarcane (Poales: Poaceae) in Argentina

Anther and pollen development in some species of Poaceae (Poales).

Anther and pollen development were studied in Olyra humilis Nees, Sucrea monophylla Soderstr, (Bambusoideae), Axonopus aureus P. Beauv., Paspalum polyphyllum Nees ex Trin. (Panicoideae), Eragrostis solida Nees, and Chloris elata Desv. (Chloridoideae). The objective of this study was to characterise, embryologically, these species of subfamilies which are considered basal, intermediate and deriv...

Effect of Micromite® on the Egg Parasitoids Ceratogramma Etiennei (hymenoptera: Trichogrammatidae) and Quadrastichus Haitiensis (hymenoptera: Eulophidae)

The effect of temperature and humidity on the bionomics of six African egg parasitoids (Hymenoptera: Trichogrammatidae).

The life table statistics of six native Kenyan species/strains of Trichogramma and Trichogrammatoidea were established using a factitious host Corcyra cephalonica, Stainton (Lepidoptera: Pyralidae), at eight different temperatures (10, 15, 20, 25, 28, 30, 32 and 35 degrees C) and two humidity levels (40-50 and 70-80%). The objective was to select insects with superior attributes for augmentativ...

Egg parasitoids (Hymenoptera: Mymaridae and Trichogrammatidae) of the gall-making leafhopper Scenergates viridis (Hemiptera: Cicadellidae) from Uzbekistan, with taxonomic notes on the Palaearctic species of Aphelinoidea.

A new species of the Aphelinoidea Girault (Hymenoptera: Trichogrammatidae), A. (Aphelinoidea) sariq Triapitsyn & Rakitov sp. n., is described from Uzbekistan. Both sexes were reared from eggs of the only known truly gall-making leafhopper, Scenergates viridis (Vilbaste), laid inside its galls on camelthorn, Alhagi maurorum Medikus; additional females were found dead inside the galls. Aphelinoid...

Egg Parasitoids of the Corn Leafhopper, Dalbulus Maidis, in the Southernmost Area of its Distribution Range

Egg parasitoids of the corn leafhopper, Dalbulus maidis (DeLong and Wolcott) (Hemiptera: Cicadellidae), were surveyed exposing sentinel eggs of the leafhopper along a latitudinal transect of 600 km in Argentina, the southernmost area of its distribution range. Four parasitoid species were obtained: the mymarids Anagrus breviphragma Soyka (Hymenoptera: Mymaridae), Anagrus flaveolus Waterhouse, a...
