“…Researchers found that this compound showed a high colony-to-colony variation when it was assayed in field trials (Calderone and Spivak 1995); in addition, high brood mortality and decline in mite reproduction during laboratory evaluations have been reported (Imdorf et al 1999). In the literature, assay using lavender essential oil have showed good mite mortality (Ardeshir et al 2002) moreover, affecting mite reproduction; but it has (Imdorf et al 1999). Also, lavender, laurel and thyme essential oils were found having repellent action on Varroa mite (Imdorf et al 1999).…”

Varroa destructor is an external parasitic mite that is a serious pest of honeybees and has caused severe losses of colonies worldwide. One of the feasible alternative treatments being used for their control is essential oils. The aim of this work was to evaluate the bioactivity of some essential oils on V. destructor and Apis mellifera in relation with their chemical composition and physicochemical properties. Lavender, lavendin and laurel essential oils showed linalool as main compound in their composition. 1,8-Cineole was also present as a predominant component in the laurel essential oil. However, thyme oil was characterized by a high concentration of thymol. Mites and bees toxicity was tested by means of complete exposure method. For mites, LC(50) values for laurel, lavender and lavendin essential oil did not show significant variation throughout all observation times. However, the LC(50) values for thyme oil at 48 and 72 h were lower than at 24 h. Bee mortality was evident only in treatment with thyme oil. At 48 and 72 h, lavender essential oil presented better selectivity indexes. In this research, all essential oils caused mite mortality without severe harmful effects on adult bees. The simultaneous evaluation of the physicochemical analysis of the essential oils, the characterization of the dosage response relationships among them, and the mortality effects on mite and bees, give us the possibility to obtain comparative results for future research in Varroa control.

“…The main experiments were done between August and October. To separate mites from infested honey bees, an instrument was designed as described by Ariana et al (2002) that had two cylinders, one inside the other. About 1000–2000 adult bees were poured into the inner cylinder and after closing the inner and outer cylinders they were exposed to C0 2 gas for 5 min with 5 l/min pressure from a gas cylinder.…”

Regular dorsal dimples and damaged mites of Varroa destructor in some Iranian honey bees (Apis mellifera)

2011

The frequency of damaged Varroadestructor Anderson and Trueman (Mesostigmata: Varroidae) found on the bottom board of hives of the honey bee, Apis mellifera L. (Hymenoptera: Apidae) has been used as an indicator of the degree of tolerance or resistance of honey bee colonies against mites. However, it is not clear that this measure is adequate. These injuries should be separated from regular dorsal dimples that have a developmental origin. To investigate damage to Varroa mites and regular dorsal dimples, 32 honey bee (A. mellifera) colonies were selected from four Iranian provinces: Isfahan, Markazi, Qazvin, and Tehran. These colonies were part of the National Honey bee Breeding Program that resulted in province-specific races. In April, Varroa mites were collected from heavily infested colonies and used to infest the 32 experimental colonies. In August, 20 of these colonies were selected (five colonies from each province). Adult bees from these colonies were placed in cages and after introducing mites, damaged mites were collected from each cage every day. The average percentage of injured mites ranged from 0.6 to 3.0% in four provinces. The results did not show any statistical differences between the colonies within provinces for injuries to mites, but there were some differences among province-specific lines. Two kinds of injuries to the mites were observed: injuries to legs and pedipalps, and injuries to other parts of the body. There were also some regular dorsal dimples on dorsal idiosoma of the mites that were placed in categories separate from mites damaged by bees. This type of classification helps identifying damage to mites and comparing them with developmental origin symptoms, and may provide criteria for selecting bees tolerant or resistant to this mite.

“…Mites for this experiment were collected from a separate set of highly infested colonies using a modification of the carbon dioxide (CO 2 ) method (Ariana et al 2002). In this method, bees infested with Varroa were placed in a box with a screen bottom and put in a Rubbermaid (3.5 L TakeAlongs TM , Rubbermaid, Mississauga, ON, Canada) container.…”

The objective of this study was to assess the effects of honey bees (Apis mellifera L.) with different grooming ability and queen pheromone status on mortality rates of Varroa mites (Varroa destructor Anderson and Trueman), mite damage, and mortality rates of honey bees. Twenty-four small queenless colonies containing either stock selected for high rates of mite removal (n = 12) or unselected stock (n = 12) were maintained under constant darkness at 5 °C. Colonies were randomly assigned to be treated with one of three queen pheromone status treatments: (1) caged, mated queen, (2) a synthetic queen mandibular pheromone lure (QMP), or (3) queenless with no queen substitute. The results showed overall mite mortality rate was greater in stock selected for grooming than in unselected stock. There was a short term transitory increase in bee mortality rates in selected stock when compared to unselected stock. The presence of queen pheromone from either caged, mated queens or QMP enhanced mite removal from clusters of bees relative to queenless colonies over short periods of time and increased the variation in mite mortality over time relative to colonies without queen pheromone, but did not affect the proportion of damaged mites. The effects of source of bees on mite damage varied with time but damage to mites was not reliably related to mite mortality. In conclusion, this study showed differential mite removal of different stocks was possible under low temperature. Queen status should be considered when designing experiments using bioassays for grooming response.
