... Aphids (Homoptera: Aphidiidae) is a polyphagous insect pest of a wide variety of crops, vegetables, fruits and decoration plants. Aphids cause damage directly (leaves deformation, flower and young fruit droop, underdeveloped shoots), or damage indirectly (honey residue causing sooty mold, virus transmission) (Naeem et al., 2005). ...

Showed the study of the Aphid parasitoids (Hymenoptera: Aphidiidae) in Dhi Qar province southern of Iraq during the months of March and April 2017 is 5 species belonging to 3 genera of Aphidiidae, Aphidius matricariae, A. funebris, A. rosae, Lysiphlebus testaceipes and Praon exsoletum, The diagnosis was based on important taxonomic characteristics such as, maxillary palpi, labial palpi, wing veins, propodium, petiole and ovary sheath.Plant
... Aphid (Homoptera: Aphididae) commonly called as greenfly, black fly or plant lice is a polyphagous pest causing damage directly and indirectly throughout the world (Naeem et al., 2005). Around 600 viruses with invertebrate vectors are transmitted by aphids (Tomlinson, 1987;Hull, 2002). ...

Melanaphis donacis (Passerini) is reported for the first time from different localities of Osia (Murree) on Arundo donax Georgi during 2016. Main identification characters supported with micrographs and measurements, synonymy and distribution have been given for further research. Ants belonging to Genus Crematogester were also found in the colonies of this aphid which confirms its mutualistic association with ants.

Aphidiinae are exclusive endoparasitoids of aphids and together with particular plant species form tritrophic complexes. Parasitoid wasps show different levels of host specificity, which is a very important fact since they have been used in biological control programs. We present a new approach to aphid parasitoid host specificity applied on 505 species from 38 genera, covering all valid species in the world fauna excluding synonyms. For this purpose, the artificial neural network visualization was performed to show the distribution and interconnections between and among members of five a posteriory selected groups of parasitoids. The results showed that about half of the analysed species (225) belong to the group of strict specialists, consisting of monophagous parasitoids that attack only one aphid species. The group of generalists assembled 58 species with mainly Palaearctic distribution. Between specialists and generalists are the oligophagous species which are clustered in three categories: narrow, moderate and broad oligophagous. Generally, host specificity in Aphidiinae is weakly connected with their phylogeny, suggesting that the parallel evolution of aphidiines must have occurred. Host specificity mainly depends on aphid hosts which follow host plant distribution.
... In neighboring countries, various workers have reported this genus (Shujaudin, 1973;Takada and Rishi, 1980;Bhagat, 1982), including the record of 16 species by Raychaudhuri (1990) from India. So far 3 species of Binodoxys have been reported from Pakistan (Starỳ et al., 1998) out of a total of 30 Aphidiinae parasitoid species (Starỳ et al., 2006;Naeem et al., 2005). Keeping in view this situation, various surveys were conducted during 2005-08 for the collection of aphid parasitoids. ...

Five species of Genus Binodoxys Mackauer, 1960 have been reviewed from Punjab Province of Pakistan. Two species namely, Binodoxys rubicula and Binodoxys angelicae are recorded for the first time from Punjab Province of Pakistan A brief taxonomic redescription of these species together with necessary measurements are presented. New locality records and host records for already recorded species have been given. A key to five species of Genus Binodoxys in Punjab Province are presented. The host range, biology and distribution have also been discussed. Eight new host plant associations and fifteen new locality records have been added.

Diaeretiella rapae (M'Intosh) (Hymenoptera: Braconidae, Aphidiinae) aphid parasitoid is reported from various districts of Punjab Province of Pakistan from a wide range of host aphids and plant associations, including some new evidences. Biological information centered development, life-stages and their micrographes, mating and oviposition, adult lon gevity and food have been discussed. Biology of the parasitoid reared on Myzus persicae aphids in the laboratory at 23±1°C have been discussed. The development cycle from larva to adult was completed in about 11.5 days at 21-23°C. The pre-mating period of males (n=10) varied between 20 and 40 minutes (mean: 28.8 min), however it was longer in females most of which rejected all copulatory attempts at least two hours after emergence . When newly emerged females were confined with males for a period of 12 h, all mated i.e., they produced progeny of both sexes. Copulation time (n = 10 pairs) was between 30 and 60 s (mean: 46.3 s). Oviposition time (n = 10 females) was between 46 and 64 s (mean: 52.6 s). Female lived longer (11.1± 0.16 days) than males (9.4 ± 0.18 days) when offered honey and water. The lifespan of adult females was shorter (10.2 ± 0.05 days) in the presence of host aphids and host plant leaves than only with honey and water.
