“…Consequently, it may also be speculated that Sarnorin has some potentials for vector control just as sulphonamides were shown to have potentials for controlling the larvae of the blow fly, Lucilia sericata (Greenwood and Harrison, 1965), mosquitoes (Eddy et aI, 1965) and R. prolixus (Musgrave and French, 1969).…”

Studies on the effects of Samorin, a prophylactic trypanocide on some aspects of the biology of Glossina morsitans were carried out. The overall performance of flies fed on rabbits injected with the trypanocide was severely affected. There were indications that the trypanocide could have adversely affected the symbiotic gut micro-fauna of the flies. Hence it is suggested that Samorin has some potentials for vector ‘control

“…Screening of potential insecticides has usually been done with larvae, since these are the normal target of the insecticides. [1][2][3][4] In contrast, investigations of insecticide resistance in these insects have formerly employed adult insects, presumably on grounds of convenience. [5][6][7] Recently, however, two slightly different methods of measuring resistance in Australian sheep blowflies, employing first stage larvae, have been prop0sed;8?~ using such tests, it has been shown that resistance levels in the adult bear no definite relation to those in the larva.9 This finding raises several problems, since the techniques employed in tests with adults or larvae were so different.…”

Relative potency of eight compounds (four pairs of similar types) to adults and old larvae of three species of cyclorhaphous diptera was determined by injection, oral or topical application. The following points emerged from comparisons of equitoxic doses: (a) C. putoria was consistently more susceptible than L. sericata. M. domestica was more susceptible to organochlorines than either of the blowflies, but less susceptible to organophosphorus, carbamate or pyrethroid insecticides; (b) the most potent insecticides (bioresmethrin, diazinon) were about equally toxic to adults and larvae of all species; but some compounds (especially DDT, gamma‐BHC and propoxur) were relatively much less effective against larvae; (c) LD50 values for oral treatments were higher than by injection, and those for contact treatments higher still. These “penetration factors” were highly correlated within each of the stages. This could be due to similarity in the cuticular barrier and (or) detoxication; (d) experiments with various synergistic compounds showed higher synergistic factors for larvae than adults (with DDT, bioresmethrin and propoxur). This probably indicates a more efficient detoxication system in the larvae, which is consistent with findings (b) and (c).

“…In early fly strikes, larvae of Lucilia abrade the skin and feed mainly on the exuding serum. Blood serum has therefore often been employed in larvicide tests against young larvae, with either wool or cotton wool to absorb the serum and toxicant (Hobson, 1937;Du Toit & Fiedler, 1953;Harrison & Johnson, 1961;Greenwood & Harrison, 1965;Shaw & Blackman, 1971). In Queensland this technique is used for testing third-instar larvae of L. cuprina, 48 h old (P.J.…”

In this method the toxicant is absorbed with blood serum onto a loose roll of chromatography paper; first-instar larvae of Lucilia cuprina (Wied.) are inserted into the air spaces of the roll and allowed to feed. Mortality of the larvae is assessed 24 h later. Typical results using diazinon, dichlofenthian and chlorfenvinphos against susceptible and resistant strains of L. cuprina showed larvae to have resistance factors 6-8 times higher than those for adults determined by established techniques.
