The aim of the study was to evaluate doses of alphacypermethrin for the control of the mite Pterolichus obtusus in laying hens under laboratory conditions. The experiment was carried out in the experimental houses of the Poultry Research Institute, Cuba, between June and July 2019. In total, 115 White Leghorn laying hens, 52 weeks old, naturally infested with the mite, were used. An initial sampling was carried out on all the birds to determine the levels of infestation and distribute them in homogeneous groups. Four doses of alphacypermethrin (1, 2, 5 and 10 ml/l) were tested by spray baths and compared with a group treated with cypermethrin (12 ml/l) and a control group. Three baths were carried out on a weekly basis. The effectiveness of the treatments was evaluated between 24- and 48-hour post-treatment. Alphacypermethrin in doses of 1 and 2 ml/l was ineffective, while in doses of 5 ...

The study aimed to determine the behaviour of ectoparasites in Pekin ducks (Anas platyrhychos domesticus) from the province of Artemisa, Cuba. Samples of 30 adult ducks of both sexes from various farms were analysed. For the sampling, three to five feathers were extracted from each corporal area (head, back, wings, cloaca area, tail, anterior thigh, pectoral area) and the indicators of invasion intensity and prevalence were determined. The collected parasites were mounted in Hoyer's solution and incubated at 28 °C for seven days for the clarification of the samples for their subsequent taxonomic identification. The specimens found correspond to the louse Neocolpocephalum turbinatum. This finding reveals that although the host of this insect is Columba livia, it can be found in other bird orders, due to gaps in biosecurity. The prevalence was 13.3% and the intensity was mild, which does ...

El presente estudio tuvo como objetivo determinar la extensidad e intensidad de invasión de ectoparásitos que afectan a aves del género Agapornis criadas en cautiverio. Se trabajó con 50 aves de 8-9 meses, procedentes de tres criaderos de La Habana, Cuba. Se colectaron las plumas remeras de ambas alas. Se encontraron los ácaros plumícolas Pterophagus spp, Dubininia melopsittaci, ácaros de la superfamilia Pterolichoidea y el piojo malófago de la familia Philopteridae. La asociación de Pterophagus spp y el ácaro de la superfamilia Pterolichoidea presentó la mayor frecuencia. Los parásitos de mayor extensidad de invasión fueron Pterophagus spp y ácaros de la superfamilia Pterolichoidea. La intensidad de invasión fue muy leve para el piojo de la familia Philopteridae, con respecto a los ácaros, que se encontraron con niveles desde muy leve hasta muy grave.
