Blood meals of female Mansonia perturbons (Walk.) collected from farms and wooded areas in southeastern Ontario were identified by the serological precipitin test. The mosquitoes had fed on birds, farm animals, humans, rodents, deer, and raccoons. Preliminary observations on host preferences indicated that birds may constitute a more important group of hosts for M. perturbans than mammals. In experimental trials, attraction of M. perturbans to mammals appeared to be related to the surface area of the host. A rather high proportion of specimens collected in nature contained the blood of more than one kind of host and, in laboratory tests, M. perturbans showed a greater tendency towards multiple feeding than was shown by three species of Aedes mosquitoes.

Blood Meals

Blood meals of engorged female Aedes mosquitoes collected from animal dwellings, light traps, and hand catches were identified by serological precipitin tests. The mosquitoes had fed on farm animals, humans, rodents, raccoons, deer, and probably foxes. Very few of the specimens had fed on birds and few contained the blood of more than one kind of host. Preliminary studies in a screened enclosure in a one-room barn that contained various combinations of domestic animals and humans indicated that a preference shown by mosquitoes for a mammalian host is related to the surface area of the host.

AbstractClosely spaced stable traps were used to determine the preferences of mosquitoes for 6 vertebrates at Kowanyama, northern Queensland, on 4 occasions during the wet and dry seasons of 1974–75. A total of 44 626 mosquitoes from 35 taxa was collected and compared with 26 215 specimens of 15 taxa trapped at Charleville, south-west Queensland, in February 1976. Host preference was analysed in detail for 11 species;Anopheles bancroftiiGiles,An. amictusEdw.,An. annulipesWlk.,An. farauti Lav.,An. meraukensisVenhuis,Aedes bancroftianusEdw.,Ae. normanensis(Tayl.),Ae. vittiger(Skuse),Culex annidirostrisSkuse,Cx. quinquefasciatusSay (=fatigansWied.) andMansonia uniformis(Theo.). All species in these experiments, including the important vector of arboviruses,Cx. annulirostris, preferred mammalian baits, especially calf, althoughAn. bancroftiiandCx. quinquefasciatuspreferred man. Blood-meals of 5802 engorged mosquitoes of 21 taxa collected from natural resting sites at Kowanyama village were analysed by the precipitin test. Mammals, particularly dogs, were the most important hosts.Cx. squamosus(Tayl.) andCx. quinquefasciatuswere the only species to feed extensively on birds (75–6 and 28–7%, respectively).Uranotaenia albescensTayl. fed almost entirely on amphibia. No seasonal shifts in feeding ofAn. bancroftii, An. annulipes, Cx. annulirostrisorCx. quinquefasciatuswere evident from either host-preference or host-feeding patterns, the latter being evaluated using a ‘ Feeding Index ’. These results are discussed in relation to the transmission of arboviruses, particularly Murray Valley encephalitis virus and pulmonary dirofilariasis of man and dogs in Australia.

AbstractThe comparative attractiveness to Glossina morsitans morsitans Westw. and G. pallidipes Aust. of donkeys, cattle, sheep and goats in the presence of wild game was examined during two investigations in a middle-veld area of Rhodesia. Host preferences were assessed by the identification of blood-meals collected in the grazing area. Both cattle and donkeys provided a high proportion of the diet. Sheep and particularly goats were fed upon to a minor degree. The significance of the findings is discussed in relation to tsetse control.

AbstractTwo techniques have been developed to investigate the incidence of multiple feeding by mosquitoes. One system detects the ABO blood group substances and can be used up to 24 h after feeding in the case of Anopheles stephensi List. and 30 h for Aedes aegypti (L.). It is limited by cross-reactions which develop between blood group substances as digestion occurs in the stomach of the mosquito. The second system detects the serum protein haptoglobins (Hp) and it is possible to detect the Hp type of blood in single feeds 20 h after feeding for Ae. aegypti and 16 h for A. stephensi. Multiple feeds taken within a short time of each other can be identified up to 16 h after completion of the meal. The minimum amount of blood necessary to effect an identification in a fresh two-part meal is 0·1 mg, which is approximately one-tenth of the total amount of blood taken. It is now therefore possible to measure multiple ‘cryptic meals’ taken from man, if they are of different Hp types. Identification of Hp from A. gambiae sp. A blood-meals has been successfully carried out using material sent from the tropics. Limitations of the techniques as applied to field collections are discussed.

Chronic Conjunctivitis

Mites from the genus Demodex are ectoparasites of many mammals, including humans. There are over 100 Demodex species, which demonstrate strong specificity in host selection [Table 1]. The mites are common in humans. It has been estimated that up to 60% of adults may be infected, but in most cases no symptoms of the disease are present. Demodex multiplication inside sebaceous glands and hair follicles can lead to skin disease in both humans and animals. In humans, the main problem is ocular demodecosis, which can cause chronic conjunctivitis and blepharitis. In this paper, we present the biology and epidemiology of Demodex species in humans as well as in domestic and farm animals. Characteristic lesions, diagnostics and treatment of demodecosis are also described
