It appears to be bivoltine and overwinters in the pupal stage outside the host body. Emergence of the parasitoid from the host's body takes place either in late nymphal (5th instar) or adult host. Pupation occurs in soil or inside surface rubbishes and is completed within 24 to 36 hours after emergence of the larvae from the hosts. At emergence from the pupa, the fly always ruptures the puparium along the definite lines. Pupal stadium durates on an average 19.2 days for male and 21.8 days for female. The rate of parasitism obtained in the laboratory was as great as 52.57%. Effects of parasitism become evident, when the parasitoid matures, this results in gross distortion of the host's abdomen, causing separation of sternites, tergites and pleurites. Parasitization of females may result in non-development or much shortening in length of the ovipositor. Abdomen becomes emptied due to consumption by the parasitoid.Abstract 2: Mating behaviour was studied in Eudorylas subterminalis (a parasite of cicadellids, including Psammotettix sp.) in the laboratory, and aspects of its biology were studied in the laboratory and field in West Berlin. Mating was preceded by chasing of the female by the male. The pipunculid appeared to be bivoltine, overwintering in the pupal stage. The larval parasite emerged from the 5th-instar nymph or adult of its host and pupated 24-36 h later in the soil or among surface litter. The duration of the pupal stage averaged 19.2 days in the male and 21.8 days in the female. Up to 52.57% parasitism occurred in the laboratory. As the parasite developed, it caused the host's body to become grossly distorted, with separation of the sternites, tergites and pleurites. In parasitized female hosts, the ovipositor was sometimes short or absent.10aagricultural entomology10abiology10aEudorylas subterminalis10ahosts10amating behaviour10anatural enemies10aparasites10aparasitism10aPipunculidae10apupal stage1 aHuq, Syed, Bazlul  uhttps://pipunculidae.myspecies.info/content/studies-mating-behaviour-including-some-biological-aspects-eudorylas-subterminalis-collin-di01928nas a2200361   4500008004100000245009800041210006900139260001200208300001200220490001500232520086000247653002801107653002301135653002301158653001201181653001201193653001201205653001101217653001001228653001701238653001701255653002001272653002701292653001501319653001601334653001001350653001401360653001701374653000901391100001801400700001601418856013201434       1990                        eng d00aSeasonal abundance of some Japanese pipunculid flies (Diptera : Pipunculidae) in paddy fields0 aSeasonal abundance of some Japanese pipunculid flies Diptera Pip  aHikosan  a115-1210 vSpecial is3 aAs part of the studies on the pipunculid flies in paddy fields, their seasonal abundance and percentage parasitism in the green rice leafhopper Nephotettix cincticeps were studied in insecticide-treated and untreated paddy fields. Four pipunculid species were frequently caught from August to October. The percentage of parasitism in host adults by the flies was high in June-July and in October-November.Abstract 2: The seasonal abundance of pipunculids and the percentage parasitism of their host, the cicadellid Nephotettix cincticeps, was studied in insecticide-treated and untreated rice fields in Japan during March-November 1983-84. Four species, Tomosvaryella oryzaetora, Pipunculus mutillatus, P. javanensis and P. orientalis, were caught frequently between August and October. Percentage parasitism was highest in June-July and October-November.10aagricultural entomology10abeneficial insects10abiological control10abiology10acereals10aecology10afields10ahosts10ainsect pests10ainsecticides10anatural enemies10aNephotettix cincticeps10aparasitism10aparasitoids10apests10aphenology10aPipunculidae10arice1 aMorakote, Rut1 aYano, Kôji  uhttps://pipunculidae.myspecies.info/content/seasonal-abundance-some-japanese-pipunculid-flies-diptera-pipunculidae-paddy-fields
