“…Formic acid has been used to control honey bee parasites in Europe for over two decades (Maul et al 1980;Ritter and Ruttner 1980). However, current application methods are labor-intensive, and efficacy varies depending on ambient temperature (e.g., Feldlaufer et al 1997;Calderone and Nasr 1999;Bahreini et al 2004), the size of the honey bee population, type of hive equipment, and the application system (Wissen and Maul 1981;Ostermann and Currie 2004).…”

This study examined the effects of indoor fumigation with formic acid on survival of honey bee, Apis mellifera L. (Hymenoptera: Apidae), queens and varroa mites (Varroa destructor Anderson and Trueman (Acari: Varroidae)). A relationship between cumulative formic acid concentration and varroa mite mortality was established for colonies subjected to high-concentration fumigation while held indoors at 2–4 °C during winter. We also examined the effects of the formic acid release pattern and room ventilation rate on queen loss and treatment efficacy during fumigation. Two experiments were conducted in a wintering building. In both experiments, room air had higher formic acid concentrations than hive air. In experiment 1, 50% and 95% of mites were killed when exposed to in-hive concentration × time combinations of 49 ppm × days (CT50 product) and 111 ppm × days (CT95 product), respectively. No queen loss was observed under either the increasing-concentration or constant high concentration fumigation pattern. In experiment 2, 33% of queens were lost when minimum ventilation was used with room air concentrations of 57 ± 8 ppm (mean ± SE), whereas no queens were lost in controls or colonies exposed to room air concentrations of 27 ± 8 ppm with variable ventilation. Queen loss was associated with peak in-hive formic acid concentrations >20 ppm, but not with CT product, suggesting that queens are affected by acute rather than chronic exposure to formic acid. Formic acid fumigation significantly reduced the mean abundance of mites under both minimum- and variable-ventilation treatments.

“…The average level of control during the 31 day treatment period in the Mite-Away II group (60.2 ± 2.2%) was significantly greater than in the control group (23.3 ± 2.6%). This moderate level of control is likely due to the fact that the level of mortality obtained with fumigants is partially dependent on temperature (Ostermann and Currie 2004; Bahreini et al 2004). The Mite-Away II label states that the ''Outside daytime temperature highs should be between 50 and 79°F at the time of application.''…”

Evaluation of Mite-Away-II™ for fall control of Varroa destructor (Acari: Varroidae) in colonies of the honey bee Apis mellifera (Hymenoptera: Apidae) in the northeastern USA

Mite-Away II, a recently-registered product with a proprietary formulation of formic acid, was evaluated under field conditions in commercial apiaries in upstate New York (USA) for the fall control of Varroa destructor Anderson & Trueman in colonies of the honey bee, Apis mellifera L. Ambient temperatures during the treatment period were in the lower half of the range recommended on the label, but were typical for early fall in upstate New York. Average mite mortality was 60.2 +/- 2.2% in the Mite-Away II group and 23.3 +/- 2.6% in the untreated control group. These means were significantly different from each other, but the level of control was only moderate. These results demonstrate that Mite-Away II may not always provide an adequate level of control even when the temperature at the time of application falls within the recommended range stated on the product's label. To make the best use of temperature-sensitive products, I suggest that the current, single-value, economic treatment threshold be replaced with an economic treatment range. The limits for this range are specified by two pest density values. The lower limit is the usual pest density that triggers a treatment. The upper limit is the maximum pest density that one can expect to reduce to a level below the lower limit given the temperatures expected during the treatment period. When the actual pest density exceeds the upper limit, the product should not be recommended; or, a warning should be included indicating that acceptable control may not be achieved.

“…Many natural compounds have been evaluated for their effectiveness against Varroa mites [1]. During the five-year period employed in this review, some papers have described the use of simple carboxylic acids, such as formic [11][12][13][14][15][16] and oxalic [17][18][19] acids. Their efficacy has been known since 1980 [20].…”

“…In many instances, lack of information about the correct identity of the mites, as Natural Acaricides Natural Product Communications Vol. 1 (12) 2006 1155 well as inadequate knowledge regarding their biology and ecology, have hampered our ability to combat effectively these mite pests. Their small size and cryptic appearance make mites difficult to detect, and thus infestations are often overlooked.…”

Dedicated to the memory of Professor Ivano Morelli.Acari are responsible for millions of dollars worth of damage each year as a result of infestations of animals, plants and man. They directly affect our health and prosperity as animal and plant parasites, vectors of disease, and producers of allergens. The indiscriminate use of pesticides has quickly induced resistance in many parasites. At present, the control of acarid parasitic diseases in agriculture, human and veterinary medicine is mainly based on the use of drugs; and for this reason the lack of effective drugs often prevents the control of some parasitic diseases, making them more serious and important. The use of commercial drugs involves many problems, besides the drug-resistance shown by the most important parasites. Environmental damage and the toxicity of many synthetic drugs, represent the main problems that strongly limit drug use. In addition, drug residues in plant and animal food products are important reasons for further economic losses for farmers and must be regarded as potentially hazardous to man and the environment. Plant-derived compounds are generally more easily degradable and could show a smaller negative environmental impact with respect to synthetic drugs. For these reasons, the evaluation of the antiacarid activity of plant extracts is increasingly being investigated in order to obtain new leads, as demonstrated by recent studies that have evaluated and confirmed the effectiveness of many plant compounds on bacteria, fungi, protozoa, helminths and arthropods. This review will be limited to the class Arachnida, sub-class Acaridi, particularly to their control in agriculture, veterinary and human medicine using natural methods.
