There is need for a simple, cheap and efficient collection and control tool for the different stable fly-species in hyper-infested foci. The efficacy of a modified unbaited Vavoua trap (MVT) was compared with an unbaited Nzi as a standard. Each trap model was pitched either inside or outside the cattle overnight pen with rotation taking place after four days for eight days in September 2018 in Ngaoundere. Fly collection was made every 24 hours and sorted using standard identification keys. In total, 2105 hematophagous flies were caught and constituted of 1417 S. niger (89 S.n/t/d), 124 S. calcitrans (8 S.c/t/d), 562 Musca spp. (25m/t/d) and 2 Chrysops distinctipennis (0.1 Cd/t/d). The overall mean catches with the MVT (50.96±57.16) was higher than with the Nzi (27.43±27.73), with no statistically significant difference (t=0.9, df=46.0, P=0.37). Higher mean catches were recorded outside the overnight cattle pen (47.79±55.27) than inside (39.83±55.40) with no statistically significant difference (t=0.5, df=46.0, P=0.62). Stable flies and tabanids were mostly caught outside the overnight stable, while Musca spp. were highly caught inside. Humidity and wind speed were the main drivers of the abundance of the flies caught and from the Pearson’s correlation test, there was a negative and significant correlation between the two meteorological parameters (r=-0.29, P=0.04). The MVT can serve as a simple and efficient tool for the survey and control of stable flies in the Adamawa plateau and elsewhere.

Digestion of DNA of the female African grey parrot (Psittacus erithacus) with the restriction endonuclease Msp1 revealed the presence of a tandemly repeated, female-specific component with a repeat monomer length of approx. 628 nts and a repeat copynumber of approx. 1.3 x 10 4 . The nucleotide sequence of a cloned 628 bp repeat monomer, is characterized by short oligo dA2-6 segments which occur with an average periodicity of 10.5 bp. The sequence shows therefore some similarity with the W-specific repeat of the chicken, which is characterized by alternating dT3-5 and dA3-5 oligonucleotides occurring each with a periodicity of 21 bp. Similar to the chicken sequence the psittacine monomers show a strong reduction in electrophoretic mobility in polyacrylamide gels. The component occurs widespread in females of many members of different subfamilies of the Psittacidae. Minor amounts of cross hybridizing material were found in males of most species tested. Only in a few species, including the Eclectus parrot (Eclectus roratus) and the Bourke’s parakeet (Neopsephotus bourkii), DNA of males contained, in addition to an abundant female specific component, significant amounts of non-sex-specific PARsex-1Arch Vet Sci Med 2022; 5 (2):004-023 DOI: 10.26502/avsm.032 Archives of Veterinary Science and Medicine 5 like material, whereas DNA of male and female keas (Nestor notabilis) contains almost nothing.
