during the study of parasitoids of leafminer flies, some parasitoid wasps belonging to the family eulophidae, including cirrospilus variegatus (masi), diglyphus isaea (walker) and hemiptarsenus zilahisebessi erdã¶s were collected and identified, of which c. variegatus is a new report for iran. the latter species was reared from liriomyza sativa blanchard (diptera: agromyzidae) on cucumber in th...

nephus (bipunctatus) bipunctatus (kugelann) is a predator of peliococcus kimmericus (kiritshenko) (hem.: pseudococcidae) on lactuca serriola l. in different parts of the fars province, iran. some parasitized larvae of this predaceous ladybird were collected, and two parasitoid wasps, homalotylus flaminius (dalman) and h. sinensis xu & he (hym.: encyrtidae), reared from these larvae in the labor...

Polyembryonic wasps are the only parasitoids in which sociality has evolved. Theory implicates both competition and sex ratio manipulation in the evolution of a sterile soldier caste. However, investment in soldiers by males and females is predicted to differ depending upon how offspring are allocated to hosts and the mating system. Here, we compared male and female soldiers in the polyembryoni...

Insect hosts can survive infection by parasitoids using the encapsulation phenomenon. In Drosophila melanogaster the abilities to encapsulate the wasp species Leptopilina boulardi and Asobara tabida each involve one major gene. Both resistance genes have been precisely localized on the second chromosome, 35 centimorgans apart. This result clearly demonstrates the involvement of at least two sep...

Sclerogibbid wasps conform a small group of chrysidoids and parasitoids embiopterans especially found in arid semiarid habitats. Although its distribution America is fairly well known, information about sclerogibbid from Argentina scarce. The first record species belonging to the family Sclerogibbidae (Hymenoptera) for province San Juan, reported. It female individual collected by pitfall trap ...

Finding a spot for her babies to grow up can be perilous for a female fruit fly. The wrong choice can sentence most of them to death at the "hands" of another insect mother, a wasp that is likewise searching for a nursery for her young (Fig 1). Wasps in the genus Leptopilina, which are the main parasitoids of Drosophila, lay their eggs in up to 80% of fruit fly larvae in the wild. As the wasp l...

Abstract The alfalfa weevil ( Hypera postica Gyllenhal, Coleoptera: Curculionidae) is a major pest of crops. Chemical control measures are inefficient, but the larvae often infested by parasitoid wasps genus Bathyplectes Förster (Hymenoptera: Ichneumonidae), which offer potential biological strategy. development effective requires identification species, conventional methods involve rearing par...

The environmental compatibility of a biological control agent is an important aspect of successful reduction of agricultural pests. Temperature fluctuations during the day have a strong influence on the performance of laboratory-reared parasitoids. In field conditions, Trichogramma (Hymenoptera: Trichogrammatidae) wasps are exposed to variable temperatures during their development, which has a ...

The Brazilian waterweed, Egeria densa Planchon, 1849 (Hydrocharitaceae), is an invasive species in South Africa where it a host plant for the aquatic leaf-miner Hydrellia egeriae Rodrigues-Júnior, 2015 (Ephydridae, Diptera). Efficacy of biocontrol agent can potentially be affected by parasitoids. Three braconid parasitoid wasps were reared from puparia . By comparison with type specimens, these...
