Garlic, Allium sativum L. and Onion, Allium cepa L. as a Potent Anti-mite Varroa destructor, Parasited on Honey Bee, Apis mellifera L. in Egypt.

Abstract

The parasitic mite, Varroa destructor is one of the most important pests attacking apiaries all over the world. The aim of work is to evaluate the effects of fresh garlic, onion, mix of them, garlic oil and onion oil against Varroa mite in the honey bee colonies in Sohag Governorate. Data revealed that, all tested materials were effective when compared with control. The treatment with fresh garlic led to the highest percentage of fallen Varroa mite with 94.29% of the total Varroa presented in the bee colony, followed insignificantly by the mixture of garlic and onion (93.60%), garlic oil (91.55%) and onion oil (89.91%), however, the lowest percentage was recorded in fresh onion treatment with 85.33% of the total Varroa presented in the bee hive. Also, it is clear that the highest reduction percentage was recorded after the first application in all materials, the number of applications needed to satisfactory Varroa control differed depending on material type.

Controlling varroa mites infesting honeybees (Apis mellifera L.) Using some essential oils and amitraz under colony conditions

“…Error) (9.330± 2.392) for the study. This is consistent with what was found when the effects of fresh garlic, onion, a combination of them, garlic oil, and onion oil against Varroa mite in honey bee colonies were evaluated, the treatment with fresh garlic resulted in the highest percentage of fallen Varroa mite with 94.29 percent of the total Varroa present in the bee colony [24] . Also, in the work by El-Nagar et al, [25] when they were studied to evaluate the effect of some botanicals-based food mixtures added to sucrose syrup and offered to honeybee colonies on the development of Varroa infestation, brood rearing activity, and clover honey, summarized results are as follow: The food mixture composed of lemon juice + garlic extract reduced significantly the rate of Varroa infestation as compared to the control in all seasons of the year by 37.02-55.40%, also, the food mixture composed of lemon juice + garlic extract induced the highest brood rearing activity in all seasons of the year.…”

High-energy emulsification of Allium sativum essential oil boosts insecticidal activity against Planococcus citri with no risk to honeybees

“…Moreover, EO doses and its application methods used for toxicological test against A. mellifera should be comparable to those used in real conditions. As an example, garlic extract and EO were safely applied on honeybee colonies by Mazeed and El-Solimany (2020) to manage Varroa destructor Anderson & Trueman.…”
