AbstractA small, undisturbed stream in central New Hampshire was treated for 1 min with a 10 ppm suspension of Bacillus thuringiensis var. israelensis (B.t.i.) to determine the effect on an outlet-breeding black fly population and associated nontarget aquatic insects. The black fly larval population was eliminated and susbsequent adult black fly biting activity reduced near the treatment site although weather conditions may also have contributed to an observed decrease in biting activity. Some Chironomidae were killed by B.t.i. but they were not abundant enough to adequately assess impact on their populations. Temporary increases in the drift of two Ephemeroptera and two Trichoptera species were observed following treatment. Increase in rate of drift was inversely related to increase in distance from the treatment point. Slight increases in observed drift of three Plecoptera species could not be attributed directly to the B.t.i. treatment. No direct mortality caused by B.t.i. was observed in any stream insects studied except black fly larvae and some Chironomidae.

AbstractThe effects of Bacillus thuringiensis var. israelensis de Barjac (B.t.i.) on the feeding habits of two black fly predators, Nigronia serricornis (Say) and Acroneuria lycorias (Newman), and a detritivore, Prostoia completa (Walker), were examined. We assessed whether B.t.i.-killed and hot water-killed black fly larvae were less or more desirable to these consumers than live larvae. Nigronia larvae showed no significant differences in predation on larvae within the three categories. Acroneuria nymphs consumed more live than dead prey. Experiments with the detritivore, Prostoia, showed that they preferred dead black fly larvae to live ones. Bacillus thuringiensis var. israelensis treatment may have little direct effect on nontarget organisms, but these studies indicate that there still may be consequences for predators and detritivores when a viable population of larval black flies is transformed into dead organic matter.

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.

AbstractTwo formulations of methoxychlor were compared with regard to toxicity and availability to aquatic organisms. A particulate formulation was less toxic than an emulsifiable formulation to chironomid larvae, stonefly nymphs, and fish. Similarly the particulate methoxychlor was less rapidly accumulated from water by those same animals than was the emulsified methoxychlor. With black fly larvae, the only filter-feeding animal used, the two formulations were about equal in toxicity, but the particulate formulation was accumulated more readily than emulsified material. Both formulations induced larvae to detach from substrate but emulsifiable methoxychlor acted more quickly. At the time of detachment, larvae exposed to the particulate formulation contained an average of 68 times more methoxychlor than larvae exposed to the emulsion.
