Jamnback %K biology %X

In feeding tests, 1.0% thiotepa (tris (1-aziridinyl) phosphine sulfide) in 5% sucrose solution was rapidly lethal to most females of the yellow-fever mosquito, Aedes aegypti (L.). At this concentration it was calculated that approximately 4600 mg of thiotepa per kg of mosquito weight was ingested.

The mortality of mosquitoes feeding on 0.1% thiotepa was 69% on day 20, 17 days after exposure, as compared with 23% in untreated mosquitoes. With 0.1% thiotepa, there was a significant reduction in the size of oocysts and obvious abnormalities in their appearance, but there was no significant difference between the numbers of oocysts in treated and untreated mosquitoes. Sporozoite production was delayed but not entirely prevented; the length of the extrinsic period being almost doubled. Dissections made on day 20 or thereafter indicate that the sporozoite rate was reduced by 68%. Transmission to chicks by thiotepa-treated mosquitoes (on day 20) was reduced by 88%. Plasmodium gallinaceum Brumpt in the 2 chicks infected by thiotepa-treated mosquitoes was infective to other mosquitoes and developed normally in them.

The effects of lower concentrations of thiotepa were studied in less detail. Sporozoite rates were reduced and the appearance of sporozoites was delayed in mosquitoes that fed on 0.01% thiotepa but were unaffected in mosquitoes that fed on 0.001% thiotepa.

The obsoletus group of the subgenus Culicoides (Avaritia) is characterized and the four eastern North American species, which were previously included under the names obsoletus (Meigen) and chiopterus (Meigen), are described with keys for identification of males and females, and when known, the larvae and pupae. These four species are alachua n. sp. from Florida; chiopterus (Meigen) not abundant, probably widespread; obsoletus (Meigen) common and widespread; and sanguisuga (Coquillett), the important pest of eastern woodlands. The known distribution and breeding habitats of these species are discussed.

Jamnback %A Watthews, T. %K biology %X

The method used in making landing-rate counts of Culicoides sanguisuga (Coquillett), an abundant pest of man in the Adirondacks, is described. Landing rates were low initially at a given site, and increased to a peak 10 to 12 minutes later. Counts were highest about an hour after sunrise and at sunset. In open meadows the counts generally declined to zero during the day between the morning and evening peaks. In moist, shaded sites, protected from the wind, landing rates diminished but punkies continued to be annoying during the middle of the clay. It is suggested that the rate of moisture loss is an important factor influencing the activity of the punkie, and a close relationship between the evaporation rate and landing rate is demonstrated. Seasonal changes in populations of C. sanguisuga, as indicated by landingrate counts and light-trap collections, were comparable. The first females appeared in late May. Populations then increased rapidly and reached peak numbers in late June and early July. The numbers diminished slowly thereafter and punkies were found only in small numbers after mid-August, although occasional specimens were present into October. C. sanguisuga overwinters in the larval stage. In 1961, larval populations were high in early May, then declined during the period of pupation from late May into early June. Numbers increased thereafter owing to the appearance of recently hatched small larvae. Prepupation population levels were reached by late July.

Jamnback %A Eabry, H. H. %K biology %X

A study of the possible cumulative effects of DDT on arthropods in streams treated for black fly larval control for 5 to 10 years was carried out in 1961. Statistical analysis based on 348 square-foot riffle samples taken in treated and untreated Adirondack Mountain streams indicates that a significantly smaller number of Ephemeroptera and Diptera were present in the regularly treated streams than in those untreated, and that the reduction in overall numbers of arthropods approached hut did not reach a significant level. The numbers of arthropods in 11 regularly treated streams sampled in 1950-52 and again in 1961 were about the same during the two sampling periods.

The ratio of weight to volume to numbers of arthropods was about the same in regularly treated, irregularly treated, and untreated streams sampled in 1961.

A method of testing and evaluating chemicals painted on window screens for control of punkies (Culicoules obsoletus (Meigen)) in dwellings consisted of using test chambers made from small cartons with one end covered by transparent plastic and the other end opaque. A screen was placed in the chamber between the light and dark ends. When the adults were introduced into the chamber at the dark end they quickly migrated to the light end passing through the treated screens. A 7.7% marathon-alcohol solution painted on screens killed Culicoides adults that had passed through them in less than an hour while a 10% DDT-oil solution required several hours before an appreciable mortality occurred. The malathion-painted screens were still highly effective in killing exposed punkies 21 days after treatment.

Jamnback %A Wall, W. J. %K biology %X

Experiments on the control of larvae of Tabanus spp. in salt marshes with granular formulations of insecticide were made on Long Island, New York, in 1955 and 1956. In 1955, granules of Attaclay or Diluex impregnated with dieldrin, aldrin, chlordane, heptachlor or DDT were applied by hand to 60-ft. square plots in salt marshes having high and relatively uniform populations of Tabanus larvae. Granules were used because they readily penetrate the dense marsh vegetation. Results were evaluated by a method in which the larvae are brought to the surface of cleared areas by the use of a pyrethrum spray [see next abstract]. Dieldrin was applied at dosages of 0.09-2.5 lb. per acre and was the most effective of the insecticides tested [cf. R.A.E., B 45 116]. No larvae could be found in plots treated with the higher dosages (0.6 Ib. or more) after ten days, or in any of the plots after 32 days, when control plots yielded 14.9 larvae per sq. yard. DDT was the least effective insecticide, giving poor control in 28 days at 2 Ib. per acre. The addition of 5 per cent. urea as a stabiliser to granules of 30/40 mesh Attaclay with 2.5 per cent. dieldrin, which was tried in 1956. did not appear to influence effectiveness.

Twenty-three species of black flies have been recorded from New York State (Stone and Jamnback, 1955). In 1955 a hitherto unrecorded species was collected on Long Island, increasing the number to twenty-four. A redescription of the female and first descriptions of the male, pupa and larva of this species are presented below. The characters used in the descriptions are discussed in the publication cited above.
