AbstractBlack fly larvae and pupae were collected on aquatic vegetation from the Penobscot River, Maine in August 1977. Cephalic apotome measurements were made on larvae of Simulium penobscotensis Snoddy and Bauer and indicated the presence of seven instars. Simulium vittatum Zetterstedt, S. fibrinflatum Twinn, and S. penobscotensis were the principal species found. The proportion of S. penobscotensis in the samples increased with water depth to 1 m.

AbstractTen species of black flies were collected from the Souris River, Manitoba between April 1977 and October 1978. Adults of Simulium luggeri Nicholson and Mickel, Simulium meridionale Riley, Simulium venustum Say, Simulium verecundum Stone and Jamnback, and Simulium johannseni johannseni (Hart) were collected feeding on livestock and humans, and are well known pest species. Simulium vittatum Zetterstedt was the most abundant species, but was not a pest on man or domestic animals. Simulium tuberosum (Lundström) and Simulium johannseni duplex Shewell and Fredeen were the least abundant species. Simulium j. johannseni, S. j. duplex, S. venustum, S. verecundum, S. tuberosum, and Cnephia dacotensis (Dyar and Shannon) appeared to be univoltine species while S. luggeri, S. meridionale, Simulium decorum Walker, and S. vittatum were multivoltine in the Souris River.An evaluation of cone, plate, rope, and wire cage sampling devices for black fly larvae and pupae indicated that cone samplers provided a more representative sample for population assessment.In a black fly control program, of the Souris River, Manitoba two separate larvicide treatments in spring may be necessary. In the case of two treatments, the first should be aimed at late instar larvae of S. j. johannseni, S. venustum, and S. verecundum. Since the majority of S. luggeri and S. meridionale would be in the egg stage at this time, a second treatment, 10–14 days later, would be necessary to control late instar larvae of these species.

Biological Potency

A cDNA was cloned from the salivary glands of a blood-feeding black fly Simulium vittatum. The encoded protein has been given the name Simulium vittatum erythema protein or SVEP, because of its ability to increase blood perfusion in skin capillaries, resulting in the well-characterized erythema of black fly bites. The full-length cDNA contains 548 base pairs which encode 152 amino acid residues of the nascent protein. Post-translational processing produces a mature, secreted protein of 133 residues with a molecular mass of 15.4 kDa. Recombinant SVEP (rSVEP) was produced in a baculovirus expression system and purified by a one-step reversed-phase HPLC procedure. Analyses of physical properties and biological potency demonstrated fidelity of rSVEP to the native protein. Recombinant SVEP relaxed rabbit aorta preparations when preconstricted with 2 micromol l-1 phenylephrine or 25 mmol l-1 K+ but not with 60 mmol l-1 K+. Further, the rSVEP-induced relaxation response of phenylephrine-constricted aorta was inhibited by glibenclamide (10 micromol l-1), suggesting that at least part of its action to relax smooth muscle may result from the opening of ATP-dependent K+ channels. SVEP is a novel salivary-gland-derived vasoactive protein that may be essential for blood feeding by black flies and could potentially enhance transmission of filarial parasites.

QUAIL (Coturnix-Coturnix Japonica) GROWER PERFORMANCE SUPPLIED WITH MANURE FLOUR DEGRADED BY BLACK FLY LARVAE (H.ILLUCENS L.) TO REPLACE FISH MEAL. This study aims to determine the manure yield of black fly larvae replacing fish meal in the quail feed of the grower phase. The materials used in this study were 100 unsexed quails, 3 weeks old; the dimension of cage was 40 x 40 x 20 cm. The quails were arranged randomly in each unit. The study was realized by using a completely randomized design (CRD) with 4 treatments and 5 replications. The treatments were R0 = 0% degraded manure flour (MHD); R1 = 4% MHD flour; R2 = 8% MHD flour; R3 = 12% MHD flour. The research variables consisted of ration consumption, body weight gain and feed efficiency. The results obtained showed that treatments provide a very significant influence (P <0.01) on ration consumption. Body weight gain and feed efficiency were not significant different (P> 0.05). The conclusion of this study is that MHD flour up to the 12% level can be used in quail rations replacing fish meal. Keywords: Quail, MHD, Fish meal.

Hollow Metal

A new method of estimating the levels of infestation of black-fly larvae in streams is described. Hollow, metal cones, 20 cm high, 10 cm in diameter at the base, and painted white, were placed in infested streams. The cones were held in position with a wire attached to the apexes and fastened to an object in the stream or on the bank. The larvae attached to the cones in preference to stones or vegetation. Counts of those attached gave estimates of the levels of infestation in the streams, the periods when greatest numbers of larvae were moving downstream, and the fluctuations in number of larvae during the summer.
