(b) Pathogens like Paenibacillus Larvae and parasites had discovered their way into the honey bee biological system. (Kluser Stephane and Peduzzi Pascal, 2007) (c) The wellness levels of honey bees experienced significant decay as was found by the arrival of stress proteins. (d) Use of Insecticides. (e) Theories have additionally proposed the radiations that were produced by the towers occupied with portable correspondence influence the honey bees in an unfriendly way in spite of the fact that this has not been validated
