SummaryThe type and degree of damage to adult workers Apis mellifera from infestation with the parasitic mite Varroa jacobsoni during development was investigated. Mean weights infested bees upon emergence as adults were 6·3% 25% less than for healthy bees. % weight loss correlated at a high level significance number mites in cell. Only 6% showed obvious physical deformation form wing damage.

Abstract Bees have a crucial role in pollination; therefore, it is important to determine the causes of their recent decline. Fipronil and imidacloprid are insecticides used worldwide eliminate or control insect pests. Because they broad‐spectrum insecticides, can also affect honeybees. Many researchers studied lethal sublethal effects these other on honeybees, some studies demonstrated correlation between colony collapse disorder bees. The authors investigated fipronil bioenergetic...

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) promotes challenging immune and inflammatory phenomena. Though various therapeutic possibilities have been tested against disease 2019 (COVID-19), the most adequate treatment has not yet established. Propolis is a natural product with considerable evidence of immunoregulatory anti-inflammatory activities, experimental data point to potential viral targets. We hypothesized that propolis can reduce negative effects COVID-19.In...

We examined the antibacterial activities of several types propolis, including Africanized honey bee green propolis and produced by meliponini bees.The activity against Micrococcus luteus Staphylococcus aureus was superior to that Melipona quadrifasciata Scaptotrigona sp propolis.Only two samples (green propolis) were efficient Escherichia coli.Melipona better than Pseudomonas aeruginosa.We concluded these resins have potential for human veterinary medicine.

Hemolymph protein measurements in honey bees, Apis mellifera L., were used to determine the efficiency of diets as pollen substitutes. Groups 120 newly emerged worker bees kept small cages laboratory and fed on bee bread or unprocessed (natural diets), soybean/yeast corn meal (alternative a sucrose solution (nonprotein diet), from adult emergence until 6 d later. The content hemolymph was determined these at 0, 2, 4, life. Additionally, vitellogenin (a major young bees) titer measured...

SummaryAdequate substitutes for pollen are necessary maintaining healthy bee colonies during periods of dearth, but testing them objectively is both time consuming and expensive. We compared two commercial diets with collected acacia pod flour (used by beekeepers in some parts Brazil) measuring their effect on haemolymph protein contents young bees exclusively fed these diets, which a fast inexpensive assay. The included new, non-soy-based, substitute diet (named Feed-Bee®) soy-based diet,...

Though the replacement of European bees by Africanized honey in tropical America has attracted considerable attention, little is known about temporal changes morphological and genetic characteristics these bee populations. We examined morphometric profiles an population collected near where original African swarms escaped, after 34 years Africanization.

Species of Cucurbitaceae are cultivated worldwide and depend on bee pollination for fruit set. Field lab experiments were conducted at Cornell University, Ithaca, NY, during 1996 1997 to determine "Howden" pumpkin (Cucurbita pepo L.) pollen removal deposition by honeybees factors relating male flower attractiveness. Several parameters evaluated in flowers anthesis: (1) from anthers honey bees, (2) the stigma (3) amount body (4) set after pollination, (5) nectary's pores Honey bees carried...

In vitro rearing is an important and useful tool for honey bee (Apis mellifera L.) studies. However, it often results in intercastes between queens workers, which are normally not seen hive-reared bees, except when larvae older than three days grafted queen rearing. Morphological classification (queen versus worker or intercastes) of bees produced by this method can be subjective generally depends on size differences. Here, we propose alternative caste female reared vitro, based weight at...

Abstract There is no use restriction associated with bees for many fungicides used in agriculture; however, this does not always mean that these pesticides are harmless nontarget organisms. We investigated whether the fungicide pyraclostrobin, which acts on fungal mitochondria, also negatively affects honey bee mitochondrial bioenergetics. Honey were collected from 5 hives and anesthetized at 4 °C. The thoraces separated, mitochondria isolated by grinding, filtering, differential...
