The anthelmintic activity of the crude extracts of fresh and dry leaf, trunk bark and root bark of the species Andira anthelmia and Andira fraxinifolia. was evaluated in the species Vampirolepis nana and Aspiculuris tetraptera. Doses of 8 g/kg/day were utilized for the leaves and trunk bark, and 1, 2, 4 and 8 g/kg/day for the root bark for the A. anthelmia, and doses of 8 g/kg/day were utilized for leaves and root bark, and of 4, 8 and 16 g/kg/day for tree bark, for the A. fraxinifolia. The dose of 8 g/kg/day of the crude extract of the fresh and dry leaf, the trunk bark and root bark, of the A. anthelmia, when compared, did not present any significant difference in the percentage elimination of V. nana, 14.9%, 16.4%, 6.3%, 17.9%, respectively. The same occurred when compared with the control group (7.4%). The doses of 2 and 4 g/kg/day, 49.4% and 42.7, respectively, were significantly more active for V. nana, in comparison with the other anatomical parts and the control group, and did not present any difference in relation to the mebendazole. The 2 g/kg/day dose was significantly more active for A. tetraptera (63.2%), in comparison with the leaves, with the root bark for the doses of 1 and 4 g/kg/day, and with the control group, 1.2%, 1.7%, 31.7%, 15.3%, 0.1%, respectively. However, it did not present any significant difference in relation to nitroscanate, this being less active than mebendazole. Although the 8 g/kg/day dose for the tree bark presented a higher percentage elimination of V. nana (37.5%), no statistical difference was observed, when compared with the other doses, anatomical parts, the control group and the mebendazole. Similarly, no significant difference was observed in the percentage elimination of A. tetraptera. The results suggested the crude extract of the root bark of the A. anthelmia as a promising anthelmintic, requiring further studies, due to the high toxicity presented

A atividade anti-helmíntica dos extratos brutos da folha fresca e seca, casca do tronco e da raiz da espécie Andira anthelmia e A. fraxinifolia, foi avaliada sob as espécies Vampirolepis nana e Aspiculuris tetraptera. Foram utilizadas as doses de 8 g/kg/dia para folhas e casca do tronco, e de 1, 2, 4 e 8 g/kg/dia para a casca da raiz de A. anthelmia, e as doses de 8 g/kg/dia para folhas e casca da raiz, e de 4, 8 e 16 g/kg/dia para a casca do tronco de A. fraxinifolia. A dose de 8 g/kg/dia do extrato bruto da folha fresca e seca, da casca do tronco e da raiz, quando comparadas, não apresentaram diferença significativa no percentual de eliminação de V. nana, 14,9%, 16,4%, 6,3%, 17,9%, respectivamente, o mesmo ocorreu quando comparadas ao grupo controle (7,4%). As doses de 2 e 4 g/kg/dia, 49,4% e 42,7%, respectivamente, foram significativa-mente mais ativas para V. nana, em comparação com as demais partes anatômicas e o grupo controle, não apresentando diferença em relação a dose de 1 g/kg/dia da casca da raiz e do mebendazol. A dose 2 g/kg/dia foi significati-vamente mais ativa para A. tetraptera (63,2%), em comparação com as folhas, a casca da raiz nas doses de 1 e 4 g/kg/dia, e o grupo controle, 1,2%, 1,7%, 31,7%, 15,3%, 0,1%, respec-tivamente. Contudo, não apresentou diferença significativa em relação ao nitroscanato, sendo menos ativa do que o mebendazol. Embora a dose de 8 g/kg/dia da casca do tronco de A. fraxinifolia tenha apresentado um percentual de eliminação de V. nana maior (37,5%), não foi observado diferença estatística, quando comparado com as demais doses, partes anatômicas, grupo controle e o mebendazol. Similarmente, não foi observado diferença significativa nos percentuais de eliminação de A. tetraptera. Os resultados sugerem o extrato bruto da casca da raiz de A. anthelmia como anti-helmíntico promissor, necessitando de estudos complementares, devido a alta toxicidade apresentada

The influence of a diet based on putrid horse meat over the post-embryonic development of Cochliomyia macellaria (Fabricius, 1775) under controlled conditions (UR 65 10% and 14 hours of photophase) was compared with the results obtained using a meat broth diet to which other sources of animal and vegetable protein were added. The flies were maintained at 30ºC, from egg until mature larvae spontaneously abandoned the diet. They were then transfered to a climatized chamber at 27ºC. The larvae and pupae viability and the weight of the mature larvae were significantly inferior, when a diet based on meat broth was used, even though the larvae period was significantly increased with this diet. This type of diet did not charge the time of development of the pupae. The inoculation of the egg mass directly over the diet was recommend, instead of the technique in which the egg masses are transfered to humid filter paper, followed by the handling of the recently ecloded larvae.

The possible dissimilitudes relating to the duration of the egg incubation period and larval stage of Cochliomyia macellaria (Fab., 1775) from offsprings of females from larvae with and without pigmentation on Malpighi tubules, morphotype 1 and 2, respectively, was questioned. The experiment was conducted in climatized chamber regulated at 30ºC, 65±10% RH and 14 hour photophase. No significant difference was observed on average duration of first and second larval instars berween the two morphotypes, taking into account not only the conventional interpretation for the reading of different development phases of the larval stages (morphotype 1:11.0 and 11.9 hours and morphotype 2:11.7 and 12.7 hours for first and second instars, respectively), but also the reading made through the interpretation preconized by Snodgrass & Hinton (morphotype 1:10.3 and 9.6 hours and morphotype 2:9.8 and 10.8 hours for the first and second instars, respectively). The incubation period was significantly longer for eggs posited by females from non-pigmented larvae.
