Honey bee colony loss continues to be an issue and no factor has been singled out as to the cause. In this study, we sought to determine whether two beekeeper-applied pesticide products, tau-fluvalinate and Fumagilin-B(®), and one agrochemical, chlorothalonil, impact the nutrient levels in honey bee workers in a natural colony environment. Treatments were performed in-hive and at three differen...

In this study, it was aimed to investigate whether amitraz and fluvalinate residues were present in the honey samples Çukurova district they would pose a risk for human health. Total 135 used with 15 extracted flower from each of Adana center, Kadirli, Kozan, Osmaniye, Ceyhan, Karataş, Yumurtalık, Tarsus Mersin centre. The represented 1550 beehives centre, 980 1050 650 750 860 740 800 950 Tarsu...

Abstract The parasitic mite Varroa destructor (Mesostigmata: Varroidae) is the main culprit of honey bee (Hymenoptera: Apidae) colony mortality in Ontario, Canada. Most beekeepers use synthetic acaricides to control V. infestations their colonies, but these products increases risk developing resistance active ingredients, which a growing concern. This study sought determine efficacy three appro...

Insecticides are widely used to control pests in agriculture and insect vectors that transmit human diseases. However, these chemicals can have a negative effect on nontarget, beneficial organisms including bees. Discovery and deployment of selective insecticides is a major mission of modern toxicology and pest management. Pyrethroids exert their toxic action by acting on insect voltage-gated s...

Varroa destructor is a well-known ectoparasite of the honey bee Apis mellifera. Amitraz and fluvalinate are highly effective miticides used against V. infestation in colonies A. Though bees more resistant to miticides, there side effects these chemicals on reproduction, olfaction, production bees. We showed negative impact amitraz reproduction colonies. Also, we assumed reduction olfaction by d...

Survival of European honey bee (Apis mellifera) colonies has been threatened over the past few decades as Varroa destructor become a growing concern on near-global scale. Prominent treatment methods have included synthetic acaricides amitraz, coumaphos, and tau-fluvalinate. Since widespread resistance to these compounds noted, this study sought investigate V. in Virginia. infestation levels api...
