APICULTURE AND SOCIAL INSECTS Formic Acid Treatment for Control of Varroa destructor (Mesostigmata: Varroidae) and Safety to Apis mellifera (Hymenoptera: Apidae) Under Southern United States Conditions

چکیده
The efÞcacy of a formic acid pad formulation was Þeld tested for control of the honey bee parasitic miteVarroa destructorAnderson & Trueman in Florida and Texas. This pad formulation gave 39.8 11.1% control at the end of a 6-wk treatment period,which did not signiÞcantly differ from the initial sample date. Coumaphos treatment provided poor control (38.4 11.1%) over the 6-wk period, conÞrming reports of coumaphos resistance in the region. Under relatively warm winter conditions in southern Texas, formic acid causedmortality of developing eggs and brood. If resistance by V. destructor to the two acaricides registered for its control in the United States continues, the formic acid pad could provide an alternative compound to use as part of an integrated pest management approach. Given the low control seen in this trial, however, modiÞcations of application technology would seem necessary.

Multiple infections of managed honeybee, Apis mellifera, colonies are inevitable due to the ubiquitous ectoparasitic mite Varroa destructor and might be an underlying cause of winter losses. Here we investigated the role of adult small hive beetles, Aethina tumida, alone and in combination with V. destructor for winter losses and for infections with the microsporidian endoparasite Nosema cerana...

Varroa destructor (Anderson and Trueman) trapped on bottom boards were assessed as indirect measurements of colony mite population differences and potential indicators of mite resistance in commercial colonies of Russian and Italian honey bees (Apis mellifera L.) by using 35 candidate measurements. Measurements included numbers of damaged and nondamaged younger mites, nymphs, damaged and nondam...

Honey bee (Apis mellifera L.) colonies bred for hygienic behavior were tested in a large Þeld trial to determine if they were able to resist the parasitic mite Varroa destructor better than unselected colonies of “Starline” stock. Colonies bred for hygienic behavior are able to detect, uncap, and remove experimentally infested brood from the nest, although the extent to which the behavior actua...

The mineral, total amino acid, and sterol compositions of pollen collected by Apis mellifera L. were compared with the pollen of a plant consumed by Bombus terrestris (L.): Arbutus unedo L. This plant provides the predominant food resource for the main autumn generation of B. terrestris in southern France. Honey bees also forage on this plant, although only for nectar. The mineral composition o...
متن کاملSocial apoptosis in honey bee superorganisms
Eusocial insect colonies form superorganisms, in which nestmates cooperate and use social immunity to combat parasites. However, social immunity may fail in case of emerging diseases. This is the case for the ectoparasitic mite Varroa destructor, which switched hosts from the Eastern honeybee, Apis cerana, to the Western honey bee, Apis mellifera, and currently is the greatest threat to A. mell...
