Field study on the efficacy of an extract of neem seed (Mite -Stop®) against the red mite Dermanyssus gallinae naturally infecting poultry in Egypt

Abstract

Infestations with the poultry red mite Dermanyssus gallinae represent a major ectoparasite problem in poultry and affects egg and meat production worldwide. The effects of the neem seed product Mite-Stop against the red poultry mite were investigated. Five primitive poultry farms in two small villages in the Nile Delta and Giza district were selected for the study. The neem extract was diluted 1:40 and 1:50 with tap water just prior to use. Application of the two dilutions of the provided product was performed to soil, cracks and crevices of the examined area as well as to mite-infested birds on day 0 and day 7. Two hours after treatment soil dust was collected from sprayed regions of the stable and from unsprayed control regions of the same stable. The treated chickens were also checked for mites 2 h after each treatment. The examination of the chickens 2 h after spraying showed that they were free of mites. The examination of treated soil with the Tullgren funnel apparatus 2 h after the first spraying on day 0 already showed a considerable reduction of living mites compared to controls. Seven days after the first treatment of the soil the number of living mites was reduced for 80% in the treated soil and decreased even more after the second spraying, since those larvae that had hatched from eggs in the meantime were killed. The 1:40 dilution of the neem seed extract with tap water was superior to the 1:50 dilution. These results clearly show a very high killing rate of the extract, if the mites come in direct contact with the compound. However, in order to obtain extinction also of hidden and freshly hatched stages repeated spraying should be done three times within 8-10 days.

Controlling honeybee pathogen by using neem and Barbaka plant extracts

“…However, the second treatment increased the dramatic reduction of the mite population. [41] The mite mortality in the present study was not as good as the one reported in the above research. The difference may be due to the species and methods of administration.…”

The efficacy of neem seed extracts (Tre-san®, MiteStop®) on a broad spectrum of pests and parasites

“…However, many of them can only be used with several precautions, since they may harm health of humans and animals or may produce residuals inside the body of farm animals, respectively, inside eggs (Mehlhorn 2008). Therefore, in recent times, many plant extracts have been tested, whether they work against endo-or ectoparasites and/or against pests, which may contaminate food and/or rooms with agents of diseases (Schmutterer 2002;Athanasiadou et al 2007;Bäumler 2007;Brown 1996;Fajimi and Taiwo 2005;Leung 1985;Mehlhorn et al 2005, Mehlhorn 2008Mehlhorn et al 2005Mehlhorn et al , 2006Mehlhorn et al , 2010Michaelakis et al 2009;Oladimeji et al 2000;Amer and Mehlhorn 2006;Abdel-Ghaffar and Semmler 2007;Abdel-Ghaffar et al 2008a, b, 2009Heukelbach et al 2006;Kim et al 2007).…”

Ovicidal and larvicidal activity of crude extracts of Melia azedarach against Haemonchus contortus (Strongylida)

“…Other workers (Omar et al 2003) have demonstrated that purified extracts of Azadirachta indica and other members of the Meliaceae family containing gedunin showed significant in vitro, but poor in vivo, antimalarial activity. Patented di-basic-ester extracts of A. indica have been proven in several in vivo and in vitro tests to eliminate infestations with head lice, P. humanus capitis (Heukelbach et al 2006;Abdel-Ghaffar and Semmler 2007); scabies mites, Sarcoptes scabiei (Abdel-Ghaffar et al 2008b); or red chicken mites, Dermanyssus gallinae (Abdel-Ghaffar et al 2008a. Seed extracts of A. indica, Vitex agnus castus and Eucalyptus citriodora oil were tested on repellent effects against mosquitoes, Aedes aegypti, Culex quinquefasciatus, ticks, Ixodes ricinus, Dermacentor reticulates, Rhipicephalus sanguineus, head lice, P. humanus capitis, and mites, Dermanyssus gallinae ).…”
