“…Queen ovaries were dissected into 2 mL 100 mM pH 7.4 HEPES buffer. The right ovary was first sectioned and carefully teased apart under a dissecting microscope to obtain counts of ovariole numbers [ 63 ]. Both ovaries were then combined and homogenized in the HEPES buffer for 30 sec by Bead Beater (BioSpec Products, Bartlesville, OK, USA).…”

“…Further complicating maintenance of a viable queen through these periods are impacts of external stressors on individual queen quality. Individual queens may show reduced oviposition, worker acceptance, or queen retention due not only to sperm depletion and age senescence, but also poor colony nutrition, injury, disease, or pesticide exposures [59][60][61][62][63].…”

Honey bee colonies maintain viable queens in part through communication with Queen Mandibular Pheromone (QMP), a mixture that signals the queen’s presence and reproductive quality to workers. In turn, workers are thought to provide retinue queen care or replace queens partially based on QMP profiles. We examined the effects of seasonal dearth (overwintering in a warm subtropical location) on queen-worker interactions. Retinue worker responses to continuously ovipositing queens were considered in view of QMP signaling and queen reproductive quality. QMP signaling was estimated from QMP residues recovered from nest worker bodies, which is the primary mode of QMP transfer from the queen to the colony at large. QMP residues varied seasonally but not at all with queen reproductive quality (spermatheca sperm storage, ovary protein and lipid contents). 9-HDA and 9-ODA were lower in January than other months. HOB decreased from July to January, while HVA, a component associated with mated queens, increased sharply in January. Despite these seasonal signaling differences, retinue workers attended queens at similar levels through the months. In terms of reproductive quality, queens did not differ over the months in matedness (spermatheca sperm storage) or physiological age (protein carbonyl content), but varied in nutrient allocation to reproductive and non-reproductive tissues. Queen ovaries contained more protein in September than in November, and more lipid in July and September than in November and January. Queen fat bodies had more protein in July than September or November, but less lipid in July and September than November or January. Retinue worker responses did not vary with seasonal QMP changes, but reflected overall continuous brood rearing efforts and queen matedness throughout the year. The absence of seasonal differences in worker responses to QMP should be considered in the broader context of continuous reproductive efforts in warm subtropical colonies.

Honey is utilized not only as a nutritive product but also in health depicted traditional medicine and also substitute treatment for clinical settings ranging from wound curing to tumor treatment. This review emphasizes the capability of honey and its importance in medicinal aspects. Conventionally, honey is used in the treatment of blindness eye problem, respiratory asthma, throat contaminations, tuberculosis, dehydration, hitches, tiredness, shakiness, constipation, eczema, hepatitis, worm plague, piles, ulcers, wounds and used as healthful supplement. The components of honey have been conveyed to exercise antimicrobial, antioxidant, anti-inflammatory, anticancer, antiproliferative, and antimetastatic properties. Agricultural pesticides effect with antibiotics is a challenging problem in modern collected honey that needs to be addressed. Honey consumed as medicine and their contamination may transfer serious health risks. Honey are polluted by pesticides, heavy metals, and radioactive materials. Pesticide deposits create genetic mutations of healthy cells. Assimilation of honey without significant its source and defensive effect might be challenging. Pure honey should be labeled to discover its composition, origin and strong activities that is unrestricted from pollutants. It also not functional to injuries or used for therapeutic determinations. This paper reviews the health impact and extent of honey contamination. Also discussed the different nanoparticles associated with honey and their characterization.
