Comb Cell Structure and Morphological Characteristics of the Chinese Honey Bee, Apis cerana cerana (Hymenoptera: Apidae), Under Successive Generations

Xiaoling Hu, Qingxin Meng, Dandan Zhi, Shangkao Deng, Wenzheng Zhao, Yakai Tian, Xueyang Gong, Kun Dong

Summary: This study examined the changes in comb cell structure and external morphology of Chinese honey bees over ten generations to determine the optimal time for comb replacement. The results showed that the color of the brood comb darkens from white or light yellow to black over successive generations. Additionally, the shape of the brood cell changes from a three-rhomboid structure to a hemisphere, and the cell body changes from a hexagonal prism structure to a cylinder. The study suggests replacing Chinese honey bee combs after eight generations to improve colony strength and production performance.

Honey bee (Apis mellifera jemenitica) colony performance and queen fecundity in response to different nutritional practices

Khalid Ali Khan, Hamed A. Ghramh, Zubair Ahmad

Summary: This study investigated the effects of different nutritional practices on queen bee fecundity and colony performance. The results showed that supplying both sucrose solution and commercial pollen substitute led to higher egg production, larger worker brood area, and larger honey store area. These findings contribute to our understanding of controlled colony performance in the absence of sufficient natural pollen resources.

Effect of non-essential amino acids (proline and glutamic acid) and sugar polyol (sorbitol) on brood of honey bees

Muhammad Noor-ul-Ane, Chuleui Jung

Summary: This study investigates the effects of proline, glutamic acid, and sorbitol on the development and survival of honey bee broods. The supplementation of proline and glutamic acid enhances the growth of honey bee larvae and pupae, while sorbitol improves larval survival. The findings suggest that the composition of pollen may influence the foraging preferences of honey bees.

Comparative assessment of various supplementary diets on commercial honey bee (Apis mellifera) health and colony performance

Saboor Ahmad, Khalid Ali Khan, Shahmshad Ahmed Khan, Hamed A. Ghramh, Aziz Gul

Summary: A healthy honey bee stock is crucial for beekeeping and ecosystem sustainability. The study found that a diet high in soybean flour, brewer's yeast, powdered sugar, skimmed milk, date palm pollen, and sugar syrup with Vitamin C significantly increased honey bee consumption and impacted various colony parameters like pollen load, brood area, population strength, and honey yield. The research suggests that supplemental diets can play a key role in enhancing bee health and colony development in environments where pollen availability is limited.

Honey bee queen health is unaffected by contact exposure to pesticides commonly found in beeswax

Alison McAfee, Joseph P. Milone, Bradley Metz, Erin McDermott, Leonard J. Foster, David R. Tarpy

Summary: This study investigated the direct impact of topical pesticide exposure on honey bee queens and found that common pesticides found in wax did not have a direct effect on queen performance, reproduction, or quality at the doses tested. The research suggests that previously reported associations between high levels of pesticide residues in wax and queen failure are likely driven by indirect effects of worker exposure on queen care or perception.

Introduction of Varroa destructor has not altered honey bee queen mating success in the Hawaiian archipelago

Lauren M. Rusert, Jeffrey S. Pettis, David R. Tarpy

Summary: The study found that the presence of Varroa mites in Hawaii may not significantly decrease the mating success of honey bee queens, with overall high levels of polyandry observed. Additionally, there was a significant association between the number of sperm stored in queen bees' spermathecae and the number of managed colonies in the mating localities.

Effect of comb age on cell measurements and worker body size

Saad N. Al-Kahtani, EL-Kazafy A. Taha

Re-using food resources from failed honey bee (Apis mellifera L.) colonies and their impact on colony queen rearing capacity

Rogan Tokach, Autumn Smart, Judy Wu-Smart

Summary: Beekeepers have been experiencing high losses of honey bee colonies for over a decade, in part due to pesticide exposure. Reusing comb from previously perished colonies is a common practice in beekeeping, but its impact on colony health is not well understood. This study demonstrates that reusing pesticide-contaminated deadout combs can negatively affect the function of colonies, particularly in the process of replacing a queen bee.

Where Is the Honey Bee Queen Flying? The Original Case of a Foraging Queen

Ignazio Floris, Michelina Pusceddu, Pietro Niolu, Alberto Satta

Summary: While reproduction is traditionally seen as the sole task of the queen bee, foraging activities are typically carried out by worker bees. However, a new observation in the countryside of northern Sardinia revealed a honey bee queen foraging on a borage flower, highlighting the potential for queens to engage in tasks normally attributed to workers. This discovery opens up new perspectives on the behavior of queen bees outside the nest and prompts further research into their capabilities and behavior.

L. A. Holmes, L. P. Ovinge, J. D. Kearns, A. Ibrahim, P. Wolf Veiga, M. M. Guarna, S. F. Pernal, S. E. Hoover

Summary: Canadian beekeepers have been facing high winter colony mortality for the past decade, resulting in the need to replace half their queens annually. They primarily import queens from warmer climates, but there are differences in morphology and fertility between imported and domestic queens. The study also found that both environment and queen stock influence colony health and productivity.

Cobalt-based nanoparticles strongly diminish CalceinAM fluorescence independently of their cytotoxic potential in human lung cell line

Mohd Javed Akhtar, Maqusood Ahamed, Hisham Alhadlaq

Summary: This study compares the effects of two types of cobalt-based nanoparticles on lung cells and finds that cobalt nanoparticles are more toxic to cells than cobalt-iron oxide nanoparticles, possibly due to the higher release of Co2+ ions by cobalt nanoparticles. Additionally, the study suggests that CalceinAM alone is insufficient to assess the toxicity of cobalt-based nanoparticles, and other methods should be used for further confirmation.
