RESUMO

Objectif: Les informations sur le coût de l'implémentation du traitement à insecticide résiduel (TIR) pour la lutte contre lAedes sont rares. Nous avons évalué le coût supplémentaire, en plus de celui des activités intensives conventionnelles de routine du programme de lutte contre Aedes (ACP) dans la ville de Santiago de Cuba, à Cuba. Méthodes: Nous avons mené létude d'analyse des coûts en 2011-2012, dans la perspective de lACP. Les sources des données étaient les registres de comptabilité, les registres d'activité du Centre ACP provincial et les comptes d'une étude d'implémentation du TIR dans 21 regroupements de 4 blocs de maisons en moyenne, comprenant 5.180 prémisses. Résultats: Le coût annuel des activités de routine de lACP était de 19,66 $ US par ménage. Les applications de TIR espacées de 4 mois d'intervalles, avec une couverture de 97,2 percent en moyenne et utilisant 8,5 g de deltaméthrine par an et par ménage, coûtent 3,06 $ US par ménage et par an. Le deltaméthrine constituait 66,5 percent de ce coût; le coût supplémentaire pour le déploiement du TIR constituait 15,6 percent du coût de routine totale de lACP et 27 percent du coût lié à la lutte de routine contre le stade adulte de lAedes. Conclusions: Le coût incrémental de l'implémentation du TIR est élevé. Il devrait être jaugé par rapport à l'effet incrémental sur la charge de morbidité causée par la panoplie d'agents pathogènes transmis par lAedes. Le coût pourrait être réduit si l'insecticide devenait moins cher, en limitant le nombre d'applications annuelles ou en ciblant les foyers importants de transmission(AU)

RESUMO

The life tables of 3 strains of Culex quinquefasciatus were studied under laboratory conditions: Slab, susceptible to reference; Old Havana, treated with cypermethrin until its fourth generation; and Cotorro, from the field. It was found that the different levels of resistance to organophosphate insecticides and pyrethroids present in the Cotorro and Old Havana strains did not influence either on the duration of the period of development of the immature stages or in the sexual proportion of the emerged adults, but they had a favorable and directly proportional effect on the survival and longevity of the adults. However, they exerted a negative and inversely proportional influence on the reproduction and population growth of these strains. Useful data for the use and management of insecticides within the strategies of control of Culex quinquefasciatus, an important vector of lymphatic filariasis, are provided.

RESUMO

Different insecticide formulations used for the control of German Cockroach, Blatella germanica (L.) were studied to know their effects on the gravid females of this species. The insecticides assayed were baygon 20% EC, diazinon 60 EC, and licon 2.5% EC. Exposure to each insecticide showed an effect on the oothecal drop (p < 0.001). Gravid females treated with baygon had the highest percent of oothecae detached (71%); whereas diazinon caused the lowest percent (33.5%). Doses of baygon, diazinon, and icon used showed that among the oothecas detached hatching occurred only in 19.01%; 34.2% and 39.11%, respectively. Of the oothecas retained by treated females, the lowest hatching percent was produced by baygon (13.79%) compared with diazinon and icon insecticides, which presented the highest hatching percentages with 39.84 and 47.82, respectively. Therefore, the effects of insecticides on females bearing oothecas may be considered at the time of selecting an insecticide to control the German cockroach.

RESUMO

Resistance to insecticides made from different chemical compounds were studied in 4 strains of Musca domestica collected from 2 poultry farms and 2 cow farms following WHO methodology. A high resistance to malathion was observed (resistance factor values ranging from 102X to 252X), and moderate, to diazinon, fenthion, dichlorvos, DDT, and propoxur. Resistance to the deltametrine and permethrin pyreturins was not observed.
