Acaricide Residues in Laying Hens Naturally Infested by Red Mite Dermanyssus gallinae
In the poultry industry, control of the red mite D. gallinae primarily relies worldwide on acaricides registered for use in agriculture or for livestock, and those most widely used are carbamates, followed by amidines, pyrethroids and organophosphates. Due to the repeated use of acaricides--sometimes in high concentrations--to control infestation, red mites may become resistant, and acaricides ...
متن کاملPrevalence and body distribution of the poultry red mite in layer farms from Markazi province of Iran
This study was aimed to determine abundance and body distribution of PRM in laying hens of Arak. A total of 1400 laying hens were randomly examined from January to June 2008. Of those, 26 (92.86%) layer farms were found to be infested with Dermanyssus gallinae (39.3%). There was significant association between prevalence and climatic conditions of the region. The most common predilection site o...
متن کاملEvolution of signal emission by non-infested plants growing near infested plants to avoid future risk.
Several plant species indirectly defend themselves against herbivory by attracting natural enemies of herbivores by releasing signal chemicals when infested. Previous empirical research suggested that the chemical signals also reflexively induce signal emission by neighboring undamaged plants. We hypothesize that such a reflexively induced signal is a defensive strategy used by undamaged plants...
متن کاملHaematophagus Mites in Poultry Farms of Iran
BACKGROUND Blood sucking mites are important avian ectoparasites which being found on bird species worldwide. Their presence are problematic for the producers either through potential direct effects on weight gain, egg production, sperm production in roosters or as nuisance pests on worker handle hens and eggs. The aim of this study was pointing out of the status of haematophagus mites. METHO...
