Random Mixing

Apiculture is one of the agricultural activities carried out widely in our country and in the world. Our society attaches great importance to beekeeping and honey products, especially honey, so bee colony health is very important in the continuity of bee products. There are many factors that can be shown to cause colony loss in bees and one of them is poisoning caused by pesticides. Causes such as improper dosing of pesticides, day-to-day spraying, or potentiation or effect differentiation due to random mixing of drugs may cause collective bee deaths. In this study, 188 dead bee samples (each sample contains approximately 100 g dead bees) from different bee farms, which were collected from beekeepers and brought to Adana Veterinary Control Institute with the suspicion of pesticide poisoning due to intensive deaths, were examined. Qualitative examination was performed by gas chromatography (GC) device. In the examination of dead bee samples, tau-fluvalinate residue was found in 2 samples in 2015 and cypermethrin residue was found in 1 sample in 2016. In 2017 and 2018, no detectable substance was detected in terms of pyrethroid pesticides. In 188 samples which we examined in terms of pyrethroit group pesticides, 1 substance was found to be toxic for bees. This shows, at the samples examined, that pyrethroid pesticides are not involved in bee colony losses in Çukurova.

Colony Loss

Stingless bees are usually common in tropical and subtropical region of the world especially in the tropical dry and humid forest. As stingless bee honey gaining reputation for its medicinal value, stingless bees keeping has been very popular in these regions of the world. In Malaysia, keeping stingless bee has only been very popular only in the last few years. The bee honey industry is a very lucrative industry and in 2013 alone Malaysia imported RM50 million ringgit worth of honey products. Although stingless bee keeping seem to be straight forward, there are a number of issues that could hinder the success. One of the main problems is colony loss which could be attributed to a number of reasons. However, the most important cause for this is stingless bees’ habitat quality. In order to prevent colony loss and honey production impact, an integrated wireless sensing solution is being implemented at stingless bee test-farm to monitor the habitat environmental requirement for healthy and productive colonies. The system consists of sensor structures placed inside and outside of stingless bee hives for monitoring internal and external environmental parameters including hazardous gases. Sensors are connected to wireless sensor networks node places close to the hives and data collected are transmitted to base station wirelessly. A networked of hives with sensor attachment are constructed around the farm to provide sufficient data for comprehensive monitoring. Data from base station are then transmitted to farmer’s mobile device for status update. This integrated system ensures changes to stingless bee hives and colonies development could be monitored real time and necessary steps and actions could be taken to prevent colony or yield loss. In this preliminary implementation comparison between environmental parameters from productive and non-productive hives are looked at especially temperature, humidity, and light intensity data.

The Impact

A cross-sectional study was carried out in Galicia, NW Spain, in order to estimate the magnitude of honey bee colony losses and to identify potential risk factors involved. A total of 99 samples from 99 apiaries were collected in spring using simple random sampling. According to international guidelines, the apiaries were classified as affected by colony loss or asymptomatic. Each sample consisted of worker bees, brood and comb-stored pollen. All worker bees and brood samples were analysed individually in order to detect the main honey bee pathogens. Moreover, the presence of residues of the most prevalent agrotoxic insecticides and acaricides was assessed in comb-stored pollen. The general characteristics of the apiaries and sanitary information regarding previous years was evaluated through questionnaires, while the vegetation surrounding the apiaries sampled was assessed by palynological analysis of comb-stored pollen. The colony loss prevalence was 53.5% (CI95%=43.2-63.9) and Nosema ceranae was found to be the only risk factor strongly associated with colony loss. The decision tree also pointed out the impact of the Varroa mite presence while variables such as apiary size, the incorrect application of Varroa mite treatments, and the presence of Acarapis woodi and Kashmir bee virus (KBV) were identified as possible co-factors.

AbstractHoney bee colony health has received considerable attention in recent years, with many studies highlighting multifactorial issues contributing to colony losses. Disease and weather are consistently highlighted as primary drivers of colony loss, yet little is understood about how they interact. Here, we combined disease records from government honey bee health inspections with meteorological data from the CEDA to identify how weather impacts EFB, AFB, CBP, varroosis, chalkbrood and sacbrood. Using R-INLA, we determined how different meteorological variables influenced disease prevalence and disease risk. Temperature caused an increase in the risk of both varroosis and sacbrood, but overall, the weather had a varying effect on the six honey bee diseases. The risk of disease was also spatially varied and was impacted by the meteorological variables. These results are an important step in identifying the impacts of climate change on honey bees and honey bee diseases.

Honey Bee Colony Losses

Abstract Global decline in insect pollinators, especially bees, have resulted in extensive research into understanding the various causative factors and formulating mitigative strategies. For commercial beekeepers in the United States, overwintering honey bee colony losses are significant, requiring tactics to overwinter bees in conditions designed to minimize such losses. This is especially important as overwintered honey bees are responsible for colony expansion each spring, and overwintered bees must survive in sufficient numbers to nurse the spring brood and forage until the new ‘replacement’ workers become fully functional. In this study, we examined the physiology of overwintered (diutinus) bees following various overwintering storage conditions. Important physiological markers, i.e., head proteins and abdominal lipid contents were higher in honey bees that overwintered in controlled indoor storage facilities, compared with bees held outdoors through the winter months. Our findings provide new insights into the physiology of honey bees overwintered in indoor and outdoor environments and have implications for improved beekeeping management.

ABSTRACT Fossil fuels are of utmost importance to the world we live in today. However, their use can cause major impacts on the environment, especially on water resources. In this regard, algae have been intensively used as a strategy for remediation and monitoring of environmental pollution due to its efficient absorption of contaminants. In this work, samples of seaweed collected in Niterói/RJ—contaminated with kerosene and diesel—were analyzed by radiocarbon (14C) accelerator mass spectrometry (AMS) and by n-alkane quantification with gas chromatography to evaluate bioaccumulation in function of the dosage of contaminants. The biogenic content measured by radiocarbon analysis resulted in 95.6% for algae contaminated with 10 mL of kerosene and 67.6% for algae contaminated with 10 mL of diesel. The maximum intensity of n-C17 n-alkane in algae with 5 mL, 10 mL, and 15 mL of diesel was 768.2, 1878.1, and 5699.2 ng.g-1, respectively. While the maximum concentration of n-C27 in algae with 5 mL, 10 mL and 15 mL of kerosene was 3.3, 35.9, and 150.3 ng.g-1. We concluded that, for both contaminants, their incorporation into algae increases as the contamination dosage increases, making this methodology an effective technique for monitoring and remediation of urban aquatic ecosystems.

Dissolved gas analysis (DGA) of transformer oil has been one of the most reliable techniques to detect the incipient faults. Many conventional DGA methods have been developed to interpret DGA results obtained from gas chromatography. Although these methods are widely used in the world, they sometimes fail to diagnose, especially when DGA results fall outside conventional methods codes or when more than one fault exist in the transformer. To overcome these limitations, the fuzzy inference system (FIS) is proposed. Two hundred different cases are used to test the accuracy of various DGA methods in interpreting the transformer condition.

Abstract The use of pesticides such as aluminium phosphide (AlP) has increased in the recent years and improved the quantity and quality of agricultural products in a number of developing countries. The downside is that AlP causes severe chronic and acute health effects that have reached major proportions in countries such as India, Iran, Bangladesh, and Jordan. Nearly 300,000 people die due to pesticide poisoning in the world every year. Poisoning with AlP accounts for many of these deaths. Unfortunately, at the same time, there is no standard treatment for it. The aim of this article is to give a brief review of AlP poisoning and propose a treatment flowchart based on the knowledge gained so far. For this purpose we reviewed all articles on the management of AlP poisoning published from 2000 till now. Using a modified Delphi design, we have designed a handy flowchart that could be used as a guide for AlP poisoning management of patients in emergency centres.
