"Incidence of some intoxications evolution in Romania in Apis mellifera carpathica bees monitored in a bee disease prevention program in the active beekeeping season of 2019"

Abstract

The aim of this paper consisted in evaluating the intoxication cases and their dynamics during the active beekeeping season of 2019 for Apis mellifera carpathica bees monitored in a program for the prevention of infectious and non-infectious diseases. Following the corroboration of the anamnestic data with the morphoclinical data, suspicion of intoxication with toxic feed (pollen), chemicals (pesticides) and medicinal products (antiparasitic products) was established, excluding other causes of illness. During the period of the study, 113 apiaries from different geographic areas of Romania were monitored; counting a number of 7007 bee families, and was identified a number of 18 apiaries (16%) with susceptibility of intoxication, including a number of 1582 bee families (22.57%). The percentage dynamics of the intoxication cases in the studied bee families was the following: 34.07% intoxication with toxic food, 59.6% intoxication with chemical substances and 6.33% intoxication with drugs. We mention that this proportion of the intoxication was on the background of an active beekeeping season in 2019 with many rainfall and extreme weather phenomena.
