Larval algae nutrition of Aedes communis (De Geer, 1776)

Hydromermis churchillensis n. sp. is described. It is distinguished from other species of Hydromermis mainly by the fused spicules and pointed termini of both sexes. One to six larval nematodes may be found in a larva of Aedes communis (DeG.). They emerge to become free-living, molt, mature, mate, and oviposit in 2 months. Host activity is hindered, pupation prevented, and the host usually killed upon emergence of the worm. Worms are found occasionally in adult mosquitoes. Host reaction as encapsulation sometimes occurs. Ectocommensal protozoa are more common on uninfected than on parasitized mosquito larvae. At Churchill, Manitoba, approximately 10% of the mosquito larvae were killed, but in individual pools the percentage reached 80%. Nematodes were irregularly distributed in the forest and transition zones, but no correlation was found between the physical features of the pools and this distribution.

Aedes Communis

The results of one season's mosquito collecting in Algonquin Park are presented giving data on relative abundance, seasonal distribution, and habitat of larvae and adults.General correlations between mosquito distribution and vegetation, and distribution and exposure are mentioned.The list of species found in the Park now includes 3 species of Anopheles, 17 of Aedes, 3 of Culiseta, 2 of Culex, 1 of Wyeomia, and 1 of Mansonia. Twenty-one of these 27 species have been taken biting man. Of these the most common in order of time of peak abundance were Aedes communis, Aedes punctor, Mansonia perturbans, and Aedes canadensis.

Replication of a subarctic Bunyavirus, California encephalitis (snowshoe hare subtype), was detected in salivary glands and thoraces of wild-caught Aedes communis mosquitoes from the Yukon Territory, after intrathoracic inoculation with 0.1 to 100 mouse LD50 virus, and incubation for 7 to 21 days throughout their viable temperature range of 0 to 23 °C. Immunoperoxidase staining confirmed that viral replication occurred in the cytoplasm of acinar cells of salivary glands, both by light microscopy and electron microscopy. Replication of another subarctic Bunyavirus. Northway, and a subtropical Flavivirus, Murray Valley encephalitis, was also demonstrated by infectivity titrations and immunoperoxidase reactions in salivary glands of A. communis incubated at 0, 13, and 23 °C for 7 to 21 days.

Twenty mosquito species were collected in a low-subarctic area located between Eastmain River and Petit-Opinaca Lake, Quebec (52°15′ N, 76°38′ W). Qualitative and quantitative analyses of larval mosquito populations identified 20 ecological units that served as larval breeding sites. The data revealed typical larval associations such as Aedes canadensis – Aedes decticus, characteristic of the open bog series, Aedes communis – Aedes pionips of alder–willow groves (Salix planifolia – Alnus rugosa), Aedes intrudens and Aedes cinereus in flooded riparian areas. The ecology of species with summer larvae is also described: Culex restuans, Culex territans, Culiseta alaskaensis, and Culiseta impatiens.

Bugher and Taylor (1949) and Hassett and Jenkins (1949) reared highly radio-active adults of Aedes aegypti (L.) from larvae kept in a solution of radioactive phosphorus. Jenkins and Hassett (1949) obtained radio-active adults of Aedes pullatus (Coq.) and Aedes excrucians (Wlk.) with an average radio-activity of 4,300 counts per minute by rearing larvae in ponds to which radio-active phosphorus was added. Jenkins and Hassett (1951), with sub-Arctic mosquitoes, chiefly Aedes communis (Deg.), produced adults with radio-activity from 100 to 3,770 counts per minute from larvae reared in vats of P32 solution; adults released and recaptured in the field had an average radio-activity of 915 counts per minute. Thurman and Husband (1951) tagged larvae with P32 and released 400,000 adult mosquitoes in California. Of this number, 249 adults were recaptured at distances up to 1⅞ mi. downwind and 1½ mi. upwind from the release point. Yates et al. (1951) and Hassett and Jenkins (1951) produced radio-active adults of Aedes sticticus (Meig.) and Aedes aegypti (L.) by allowing them to feed on P32 solutions; the radio-activity was readily detectable with a Geiger counter for as long 13 days.

Aedes Communis

SUMMARYStrains of California encephalitis virus (snowshoe hare subtype) were isolated from 8 of 475 pools comprising 23747 unengorged female mosquitoes of five species collected at three of six locations throughout the Mackenzie Valley of the Northwest Territories, Canada, from latitudes 60 to 69° N between 10 and 24 July 1976. Minimum field infection rates included 1:2734 for Aedes communis, 1:256 to 1:3662 for A. hexodontus and 1:911 to 1:1611 for A. punctor. Northway virus was also isolated from 1 of 3662 A. hexodontus mosquitoes collected at Inuvik (69° N, 135° W). Transmission of CE virus by A. communis infected by feeding on virus in defibrinated blood and incubation at 0, 13 and 23 °C for 13–20 days clearly demonstrates the importance of this species as a natural vector, and transmission of CE virus by Culiseta inornata after incubation at 0 and 13 °C following intrathoracic injection strengthens evidence of its role as a natural vector. Immunofiuorescence was less reliable than imunoperoxidase for detection of CE viral antigen in mosquito salivary glands.
