a survey on the genus exallonyx kieffer, 1904 (hymenoptera: proctotrupidae) was conducted in northern iran. the specimens were collected using malaise traps during 2010–2011. the genus exallonyx and six species were collected and identified for the first time from iran: exallonyx ater (gravenhorst, 1807), e. brevicornis (haliday, 1839), e. formicarius kieffer, 1904, e. ligatus (nees, 1834), e. ...

Abstract Spodoptera frugiperda is a newly discovered pest in Indonesia. S. attacks can cause crop failure and significant losses. As preventive control measure, research was conducted to determine the most effective parasitoid controlling . This used egg parasitoids ( Telenomus remus Trichogramma chilotraeae) larval Microplitis manilae ). done by exposing 50 eggs of each ten larvae M. Ten repli...

In the study of parasitoids of the plane leaf miner Phyllonorycter platani during 2004, 18 polyphagous parasitoid species were recorded in four tree rows and four parks in Serbia (3 species of the family Ichneumonidae and 15 species of the family Eulophidae). Among the recorded parasitoids, the most significant were the species Minotetrastichus platanellus, Pediobius saulius and M. frontalis, f...

Parasites of adult bees are almost exclusively flies and the most important of them are conopids. This note registers for the first time the association of species of Physocephala (Diptera: Conopidae) with Centris (Heterocentris) analis (Fabricius). From 26 females and nine males of the host species found dead inside trap-nests on the campus of the University of São Paulo, Ribeirão Preto, Brazi...

Parasitoids exploit numerous chemical cues to locate hosts and food. Whether they detect and learn chemicals foreign to their natural history has not been explored. We show that the parasitoid Microplitis croceipes can associate, with food or hosts, widely different chemicals outside their natural foraging encounters. When learned chemicals are subsequently detected, this parasitoid manifests d...

In 1990-1996, we evaluated the relative importance of the Amazonian fly (Metagonystilum minense) and the wasp (Cotesiaflavipes), in sugarcane crops, in Central Venezuela. We observed a significant decrease in relative abundance of Diatraea spp. when the Amazon fly abundance increased but not with the wasp abundance. Diatraea spp. abundance in presence of both parasitoids was similar to its abun...

We tabulated ßowering plant species visited by 151 species of parasitic Hymenoptera. These data were extracted from records of C. Robertson who collected .15,000 insect visitors of ßowering plants in central Illinois during a 33-yr period. Species diversity of parasitoids was highest on plant species of the Apiaceae and Asteraceae. The most abundant parasitoids were 2 tiphiid and a scoliid spec...

the present paper provides the updated checklist of the genera and species in the subfamily alysiinae (hymenoptera: braconidae) from iran. a total of 55 species belonging to 13 genera have been listed, that had been recorded from 15 provinces. the recorded species belong to the genera alloea haliday, 1833 (one species), aphaereta foerster, 1862 (two species), aspilota foerster, 1862 (two specie...

The tachinid parasitoids (Diptera: Tachinidae) of the pine processionary moth ( Thaumetopoea pityocampa ) were studied in 2019 and 2020 Eastern Rhodopes (Fotinovo, Kandilka Sarnak vills.), Western (Dobrostan vill.) Struma Valley (town Sandanski). In total, 1193 larvae pupae T. collected 40-50-year-old Pinus nigra plantations. They transported observed laboratory conditions at 20-22 °&am...
