Abstract Colony Collapse Disorder (CCD) has been associated with Israeli acute paralysis virus (IAPV). CCD poses a serious threat to apiculture and agriculture as whole, due the consequent inability provide necessary amount of bees for pollination critical crops. Here we report on RNAi‐silencing IAPV infection by feeding double‐stranded RNA, an efficient feasible way controlling this viral disease. The association is discussed, well potential CCD.
• Floral scent is a complex trait of biological and applied significance. To evaluate whether production originating from diverse metabolic pathways (e.g. phenylpropanoids isoprenoids) can be affected by transcriptional regulators, Arabidopsis PRODUCTION OF ANTHOCYANIN PIGMENT1 (PAP1) transcription factor was introduced into Rosa hybrida. Color profiles PAP1-transgenic control (β-glucuronidase-expressing) rose flowers the expression key genes involved in secondary metabolites were analyzed....
Significance Omega-3 is an essential polyunsaturated fatty acid (PUFA) that most animals need to acquire in their diet. Mammalian brains are rich docosahexaenoic (DHA), a long-chain form of omega-3, whose deficiency, coupled with high omega-6:3 ratio, leads numerous cognitive disorders and mental diseases. Insects have only trace amounts PUFAs, the effect omega-3 deficiency on cognition has not been studied. We found greatly impaired honey bee learning, extending finding importance...
The mite Varroa destructor is an obligatory ectoparasite of the honey bee (Apis mellifera) and one major threats to apiculture worldwide. We previously reported that bees fed on double-stranded RNA (dsRNA) with a sequence homologous Israeli acute paralysis virus are protected from viral disease. Here we show dsRNA ingested by transferred parasitized bee. This cross-species, reciprocal exchange between engendered targeted gene silencing in latter, resulted over 60% decrease population. Thus,...
Abstract Rose (Rosa hybrida) flowers produce and emit a diverse array of volatiles, characteristic to their unique scent. One the most prominent compounds in floral volatiles many rose varieties is methoxylated phenolic derivative 3,5-dimethoxytoluene (orcinol dimethyl ether). Cell-free extracts derived from developing petals displayedO-methyltransferase (OMT) activities toward several substrates, including 3,5-dihydroxytoluene (orcinol), 3-methoxy,5-hydroxytoluene monomethyl ether),...
Abstract. A proximate-level hypothesis was tested about decision making in honey bees, Apis mellifera. Fifteen bees were given binary choices between artificial flowers that varied depth and volume of sucrose-water delivered. Three violated weak stochastic transitivity, under an assumption the order which ranked along a utility scale; they preferred flower to B, B C, C D, but D A. These also strong focuses on strength rather than direction preference. An intransitive pattern choice supports...

Floral pollen is a major source of honey bee nutrition that provides them with micro- and macro-nutrients, including proteins, fatty acids, vitamins, minerals. Different pollens vary in composition, the essential alpha-linolenic acid (omega-3) linoleic (omega-6). Monocultures, prevalent modern agriculture, may expose colonies to unbalanced omega-6:3 diets. The importance omega-3 diet for adequate learning cognitive function, focus on suitable ratio, well documented mammals. We have recently...
Foraging decisions of social animals occur in the context groups, and thus may be subject to considerations not only an individual's nutritional state nutrient input, but those group which they live. In eusocial insects, live colonies containing workers that forage for food is mostly consumed by others, foraging reflect colony needs also considered at both individual level. If energy balance perturbed, counteracting response occurring on level (a change division labor) or choices)? To...
Systemic RNAi, initiated by double-stranded RNA (dsRNA) ingestion, has been reported in diverse invertebrates, including honey bees, demonstrating environmental uptake that undermines homologous gene expression. However, the question why any organism would take up from environment remained largely unanswered. Here, we report on horizontal flow among bees mediated secretion and ingestion of worker royal jelly diets. We demonstrate transmission jelly-secreted dsRNA to larvae is biologically...
The study of insect behavior, particularly that honey bees, has a broad scope and significance. Tracking bee flying patterns grants much helpful information about behavior. However, tracking small yet fast-moving object, such as bee, is difficult. Hence, we present artificial intelligence, machine-learning-based recognition, systems to assist the researcher in studying bee's To develop machine learning system, labeled database required for model training. address this, implemented an...
