  • Factors influencing the predation rates of Anisops breddini (Hemiptera:
           Notonectidae) feeding on mosquito larvae

    • Authors: R. Weterings, K.C. Vetter, C. Umponstira
      First page: 107
      Abstract: Notonectidae are a family of water bugs that are known to be important predators of mosquito larvae and have great potential in the biological control of vector mosquitoes. An experiment was conducted to assess mosquito larvae predation by Anisops breddini, a species common to Southeast Asia. The predation rates were recorded in context of prey density, predator density, predator size and prey type. Predation rates were strongly affected by prey type and less by prey density and predator density. They ranged between 1.2 prey items per day for pupae of Aedes aegeypti and Armigeres moultoni to 5.9 for Ae. aegypti larvae. Compared with studies on other Notonectidae species, the predation rates appear low, which is probably caused by the relative small size of the specimens used in this study. An. breddini is very common in the region and often found in urban areas; therefore, the species has potential as a biological control agent.

      Abstract: A colony of the encyrtid wasp Psyllaephagus euphyllurae (Masi) (Hymenoptera, Encyrtidae) has been established in the quarantine laboratory at the University of California, Riverside, California, USA as part of a classical biological control program against its invasive host, the olive psylla, Euphyllura olivina (Costa) (Hemiptera, Psylloidea, Liviidae), an important pest of olives in some parts of the world. The colony originators were reared from the same host found on abandoned, commercial olives in Catalonia, Spain; additional collections were made in Murcia. The parasitoid reproduces primarily by thelytoky; however, a few occasional males have been found in the field in Spain, but not in colonies reared under quarantine or laboratory conditions. Here, the female of P. euphyllurae is redescribed and its male is described and illustrated for the first time; the only previous mention of male P. euphyllurae was from Tunisia, reared from the same psyllid host but without any details on its morphology. A lectotype is designated for Encyrtus euphyllurae Masi. Information is given on the results of genetic matching between the two sexes of the parasitoid and also on the presence of the bacterial Wolbachia symbiont that apparently is affecting reproduction of this species, including its sex ratio in the field. Two species of hyperparasitoids have also emerged from the parasitized olive psylla nymphs from Catalonia: numerous specimens of Apocharips trapezoidea (Hartig) (Hymenoptera, Figitidae) and one specimen of a Pachyneuron sp. (Hymenoptera, Pteromalidae).

  • A six-arm olfactometer for analysing olfactory responses of Goniozus
           legneri Gordh (Hymenoptera: Bethylidae), the larval ectoparasitoid of
           carob moth

    • Authors: M. Aleosfoor, F. Ehteshami, L. Fekrat
      First page: 119
      Abstract: The behavioural responses of Goniozus legneri were investigated in a six-arm olfactometer. Among the different odours examined, carob moth (Ectomyelois ceratoniae Zeller) frass elicited the highest olfactory responses, while Ephestisa larvae, which were less suitable hosts, elicited the lowest response. The different preferences to various odours suggest that Goniozus legneri can discriminate among suitable and less suitable insect hosts.

  • Synanthropic flies of Asir Province, southwest of Saudi Arabia

    • Authors: M.A. Kenawy, H.A. Al Ashry, M. Shobrak
      First page: 123
      Abstract: A survey of synanthropic flies was carried out in 11 slaughter houses in 8 localities representing different altitudes in Asir. Flies were sampled twice a month from December 2008 to November 2009 by Final Flight Fly Traps. A total of 11,737 flies consisting of 19 species, belonging to 7 families were collected, of which those of family Muscidae predominated (94.88%) followed by Calliphoridae (3.12%), Sarcophagidae (1.22%) and Fanniidae (0.55%). The other 5 families (Piophilidae, Oestridae, Phoridae, Ulidiidae and Lonchaeidae) totally represented 0.79%. Of the identified species, Musca domestica was predominant (94.26%) followed by Lucilia sericata (1.51%), Sarcophaga carnaria (1.01%), Chrysomya albiceps (0.67%), Fannia canicularis (0.55%), Chrysomya marginalis (0.54%), Muscina stabulans (0.52%), Calliphora vicina (0.39%), Wohlfahrtia nuba (0.14%), Megaselia scalaris (0.08%), Lonchaea sp. (0.06), Bercaea cruentata (0.05), Ophyra sp. and Oestrus ovis (0.04% each), Atherigona sp., Piophila casie and Physiphora demandala (0.03% each) and Parasarcophaga ruficornis (0.01). Flies altogether were more common (16 spp., 84.21%) and abundant (36.45 fly/trap) in highlands than in the other altitude levels. The highlands were found with the maximum Simpson (1-D=0.18) and Shannon (H=0.49, P<0.001) diversity indices. Likewise, the highest density of M. domestica was in the highlands (P<0.05). Regression analysis confirmed that house fly density was directly related to the altitude level (P<0.05). In all altitude levels, housefly was active during the whole year with higher activities during months of low and moderate temperatures (spring, autumn and winter seasons). Analysis revealed that fly density had inverse relation with temperature.
