“…This result was confirmed in previous trials by numerous researchers used different thymol and oxalic acid treatments [16][17][18][19] . On the other hand, it was reported that a 4.6% oxalic acid dehydrate solution had negative effects on bee population [19] .…”

In the present study, two organic compounds (thymol crystals and oxalic acid crystals in bee cake) with pollen supplement feeding were used to treat colonies against Varroa destructor. The organic compounds were applied as follows: (1) 10 g of powdered thymol was added to the bee cake prepared with fat-free soy flour, pollen and 1:1 sugar syrup (TBC), (2) 4 g of oxalic acid was prepared using the same cake recipe described above (OBC), (3) untreated colony (CC). 60 g of cakes from both treatments applied on the top of the frames in colonies. Treatments were carried out in three applications and mite fall were counted weekly during the experiment. The best result was obtained with thymol-bee cake (92.85%). The efficacy of oxalic acid treatment was recorded as 66.72%. There was no significant difference in the level of parasitization inside cells, bee population and brood area among treatments. However there was a significant reduction in mite infestation on adult bee with thymol-bee cake. This result indicates that thymol added to the bee cake is an effective, easy and safe alternative fall treatment for varroa mites.

“…For colony strength assessments, we averaged measurements taken by two observers for frames of adult bees and total brood with visual estimates per Skinner et al (2001) and transformed the measurements with conversion formulas per Burgett and Burikam (1985). To determine the number of mites per bee, per sealed brood cell, and per colony, we collected an alcohol sample of *300 bees and took two frames of capped brood from every colony for further analysis (Delaplane and Hood 1997) In October 2007, we measured brood cell size to confirm that the foundation had been drawn into correctly sized cells.…”

The efficacy of small cell foundation as a varroa mite (Varroa destructor) control

Due to a continuing shift toward reducing/minimizing the use of chemicals in honey bee colonies, we explored the possibility of using small cell foundation as a varroa control. Based on the number of anecdotal reports supporting small cell as an efficacious varroa control tool, we hypothesized that bee colonies housed on combs constructed on small cell foundation would have lower varroa populations and higher adult bee populations and more cm(2) brood. To summarize our results, we found that the use of small cell foundation did not significantly affect cm(2) total brood, total mites per colony, mites per brood cell, or mites per adult bee, but did affect adult bee population for two sampling months. Varroa levels were similar in all colonies throughout the study. We found no evidence that small cell foundation was beneficial with regard to varroa control under the tested conditions in Florida.

“…An enormous number of studies have been conducted regarding the details of application under different climatic and beekeeping conditions, i.e. concentration, time and number of treatments, method of application (powdering, feeding, evaporating, fumigating, trickling or spraying) and others (Calderone, 1999;Calderone and Nasr, 1999;Charrière and Imdorf, 2002;Della Vedova and Milani, 1999;Fries, 1989;Milani, 2001a;Nanetti et al, 2003;Rademacher and Harz, 2006;Skinner et al, 2001;vanEngelsdorp et al, 2008b).…”
