this paper reports the occurrence of the hymenoterous parasitoid of the diamondback moth larvae in iran. one species of ichneumonidae, diadegma anurum (thomson), was collected from larvae of plutella xylostella (l.) (lep.: plutellidae). this parasitoid, which belongs to the subfamily campopleginae and tribe limneriini, is a new record for iran.

three genera and species from the family ichneumonidae, viz. diadegma majale gravenhorst, campoletis thomsoni roman and hyposoter notatus gravenhorst are newly recorded from iran. these species were collected from shiraz and vicinity and the identification confirmed by jussila, finland, university of turku. the members of the subfamily campopleginae to which these three species belong are known...

this is a report on the occurrence of the hymenoterous parasitoid of the beet moth, scrobipalpa ocellatella boyd (lep.: gelechiidae), in iran for the first time. diadegma pusio (holmgren) was collected from the larvae of s. ocellatella in the sugar beet fields located in ray, the southern district of tehran. this ichneumonid species is belonging to the subfamily campopleginae and tribe limneriini.

Laboratory tests with Diadegma insulare (Cresson), a parasitoid of the diamondback moth ( Plutella xylostella (L.)), were conducted to evaluate the viability of cocoons stored at 4 ° C for varying lengths of time and also the effects of parasitism by D. insulare on the feeding rate of diamondback moth larvae. The percentage of adults emerging from cocoons declined steadily with time spent in st...

The effects of two neem insecticide formulations (an oil-free powder formulation and an oil formulation) on field parasitism of diamondback moth, Plutella xylostella (L.), larvae and, on the longevity and foraging behaviour of Diadegma mollipla (Holmgren), were evaluated in field and laboratory tests. Overall, larval parasitism in plots sprayed with the oil-free neem formulation was not signifi...

Abstract Diamondback moth, Plutella xylostella (Linnaeus) (Lepidoptera: Plutellidae), a globally important pest of Brassicaceae crops, migrates into all provinces Canada annually. Life tables were used to determine the mortality levels contributed by parasitoid complexes associated with diamondback moth in British Columbia, Ontario, Prince Edward Island, and insular Newfoundland. Overall, popul...

Field and laboratory studies on Nosema bombycis infecting diamondback moth (DBM), Plutella xylostella (L.), were conducted. Percent N. bombycis infection and mean infection intensity were significantly different (P<0.05) among DBM larvae or pupae collected from either highland (CH) or lowland (SG) areas. Percent infection was significantly higher (P<0.05) for both larvae and pupae (71.3 and 66....
