All vector control programs emphasize the use of biological control. Anisops sardea (Notonectidae: Hemiptera) and Orthetrum chrysostigma (Libellulidae: Odonata) were common in freshwater communities in Mosul. They were predators of wing-wing larvae. The effectiveness of predisposition, efficacy of research, Study on predators O. chrysostigma, A. sardea using the incomplete stages of mosquitoes Culex pipiens molestus and Chironomus ninevah in the laboratory. Backbones consumed 9.0, 8.0, 6.7 and 6.7 of the four larval ages respectively and 5.3 virgins within 24 hours while the mantis nestled at the same time 8.7 6.7, 6.3 and 5.3 larvae of the four ages respectively and 3.3 virgins. Both predators preferred the third and fourth stages when faced with all the incomplete stages of the prey. The co-existence and synergy between predators O.chrysostigma and A.sardea increased the effectiveness of predation by 17% together. The number of prey consumed per day increased with increasing density in the predators' Search coefficient for both predators. The Orthetrum chrysostigma preferred the Hamoush larvae to the mosquito larvae while the  Anisops sardea preferred mosquito larvae to the Hamoush  larvae significantly.

Tiger Beetle

Last July (1922) a species of beetle, kindly identified by Dr. G. A. K. Marshall as the Tiger beetle, Cicindela octoguttata, F., a common Tropical African species, was observed to prey on mosquito larvae at Accra, in the Gold Coast. As this habit of the beetle does not appear to have been previously observed, and as it is perhaps remarkable that it should prey on such entirely aquatic insects as mosquito larvae, the following brief note may prove of interest.

The present study examined the efficacy of λ-cyhalothrin, pyriproxyfen and granular formulations of spinosad and temephos for the control of mosquito larvae present in experimental tires in Veracruz State, Mexico in the period 2015–2016. Both λ-cyhalothrin and spinosad granules provided control of larvae and pupae of Aedes aegypti, Ae. albopictus and Culex spp. in used tires in Veracruz State, Mexico, over a 9–12 week period, although numbers of Culex were low. The numbers of Aedes larvae + pupae in pyriproxyfen and temephos-treated tires were slightly less than half of the untreated control tires, probably a result the pupicidal characteristics of pyriproxyfen and possible resistance in the case of temephos. Spinosad was less harmful to predatory Toxorhynchites spp. than λ-cyhalothrin or temephos. The reduced susceptibility to temephos in Aedes populations was confirmed at five other sites in Veracruz. Public health authorities should consider incorporating spinosad as a larvicide in coastal areas at a high risk of dengue, chikungunya and Zika outbreaks in this region.

SOME PREDATORS OF AEDES STIMULANS (WALK.) AND AEDES TRICHURUS (DYAR) (DIPTERA: CULICIDAE) IN WOODLAND POOLS

The Times

The predators of first- and second-instar larvae of Aedes stimulans and A. trichurus in temporary woodland pools near Belleville, Ontario, were determined mainly by use of mosquito larvae tagged with radioactive phosphorus, but in part from the presence of aedine remains found in the digestive tracts of dissected beetles. Of 428 pond animals collected from the test pools 122 were found to be radioactive above background. Among the 17 species of aquatic insects and other animals that fed on mosquito larvae, 8 species of Dytiscidae, 1 of Hydrophilidae, 1 of Limnephilidae, and 1 pond snail are regarded as important predators. Three additional species of water beetles were identified as predators from aedine remains in their digestive tracts. The abundance of the predators, and the times of occurrence of six species in relation to mosquito development, are discussed.

Insect Predators

AbstractMosquito larvae tagged with radioactive P32 were released in woodland pools to identify their predators. Fourteen of 38 species of aquatic insects collected had ingested tagged Aedes. The leading predators were Dytiscidae and one species each of Gyrinus, Gerris, Callicorixa, and Asynarchus. Records are new for Asynarchus sp., Callicorixa audeni Hung., Dytiscus sp., Gerris buenoi Kirk., and Ilybius discedens Shp. The mosquito predator fauna at Cordova Mines and that of previously studied pools at Chatterton, Ontario, are compared.

Study to assess the larvicidal property of Lantana camara leaves against Aedes triseriatus larvae found that the ethyl acetate extract had profound larvicidal action with the crude extract having a LC50 value of 409.831ppm. GC-MS analysis of the ethyl acetate extract confirmed the presence of twenty-one compounds out of which beta-caryophyllene covered the highest percentage of the chromatogram area. Further tests with beta-caryophyllene against the mosquito larvae proved it to be the active ingredient of L. Camara with a LC50 value of 104.243ppm.
