A study was conducted at the southern belt of Kaski District during August 2003 to July 2004 to identify natural enemies of honey bee Apis cerana Fab. and associated problems in beekeeping. Four species of wasps viz: Vespa velutina, V. bicolor, V. tropica and V. basalis were observed preying on Apis cerana. Six species of Ants were collected from hive attacking honey bees viz Componatus sp, Sima sp, Monomorium sp, Myrmica sp and two unidentified. Four species of spider viz Palatar indicus, Ariope areuta and the other two belonging to family Theridae and Araneidae were collected from the hives. Two species of Birds, Green bee- Eater and Drongo; One species of Beetle, One Chalcid (Antrocephalus sp) were identified.The disease Thaisac brood, Mite, Wax Moth and pesticide damage, deforestation, absconding of bees, lack of technical knowledge were important problems for apiculture in study area.  Key words: Apis cerana F; Enemies;  Pesticide;  Absconding;  Kaski  Journal of Natural History MuseumVol. 24, 2009Page: 89-95

AbstractVibro-acoustic communication is used by honey bees in many different social contexts. Our previous research showed that workers interact with their queen outside of the swarming period by means of wing-beating behaviour. Therefore, the aim of this study was to verify the hypothesis that the wing-beating behaviour of workers attending the queen stimulates her to lay eggs. The behaviour of workers and the queen was recorded using a high-speed camera, at first in the presence of uncapped brood in the nest and then without one. None of the queens performed wing-beating behaviour. On the other hand, the workers attending the queen demonstrated this behaviour two times per minute, on average, even in the presence of uncapped brood in the nest. After removing the combs with the uncapped brood, the incidence of wing-beating behaviour increased significantly to an average of four times per minute. Wing-beating behaviour did not differ significantly in its characteristics when uncapped brood was present or absent in the nest. During 3 days after removing the combs with the uncapped brood, there was no significant increase in the rate of egg lying by the queen. Therefore, the results presented here do not convincingly confirm that the wing-beating behaviour of workers affects the rate of queen's egg-lying. This negative result can be related to colony disturbance and longer time required by the queen to increase egg production.

Abstract Honey bees are very valuable to human. These social insects contribute in the pollination of many crops. Also, the products from honey bee colonies have many nutritional and medicinal benefits. Thus, keeping honey bees are very valuable and can be considered as source of income to many families. There are many diseases and pests that attack honey bee colonies. The pests attack bee colonies include: hornets, wax moths, bee-eater birds, and beetles. Such challenges can impact the survival and productivity of honey bee colonies. In this study, some beetle species belong to Fam. Nitidulidae, Dermestidae and Mycetophagidae were detected in honey bee colonies in Egypt, during spring. Despite the presence of many beetle species in the agricultural environment, only few species preferred the invasion of the colonies for feeding. These beetles do not attack stages of honey bees. They only feed on stored pollen or bee bread, especially those fallen on the bottom of the beehives. This is an alarm to follow the feeding behavior and distribution of these beetles. These beetles’ species can be considered as potential pests to weak honey bee colonies, housed in old or damaged beehives. The presence of large numbers of these beetles in weak colonies may disturb the activities of the bees and may passively impact the survival of the colonies. Listing these beetles is very important to better understanding the interaction between honey bees and beetles. On the other side, small hive beetles were not detected in the colonies. These beetles are currently one of the major problems facing honey bees in different parts of the world. This study confirms the absence of small hive beetles from Egypt.

Paralysis Virus

Honey bees are essential to the functioning of terrestrial ecosystems. However, despite no single factor being blamed for losses of honey bee colonies in Europe and the USA, viruses have been considered as a major driver. Moreover, a virus vector can enhance the titer and virulence of virus such as Varroa destructor can change the virulence of the deformed wing virus. Here, we report molecular evidence for aphid lethal paralysis virus (ALPV) infecting Vespa velutina, which is an important predator of honey bees, especially of Apis cerana. Viral replication and phylogenetic analysis indicated that ALPV can not only replicate in V. velutina and A. cerana, but ALPV from A. cerana (ALPV-Ac) was also significantly associated with that of V. velutina (ALPV-Vv), though distinct from those of Apis mellifera (ALPV-Am). The host state posterior probability displayed that V. velutina is the main viral reservoir between V. velutina and A. cerana. Our results show ALPV had expanded host diversity resulting in potential impacts on the health of pollinators, even on the pollination ecosystem. We suggest further studies should investigate potential risks and impacts on pollinator populations of hornets. These results should have an impact conservation efforts focused on sustaining native pollinator abundance and diversity, and therefore, the crucial ecosystem services that they provide.

Transmission of honey bee viruses to other insects, and vice versa, has previously been reported and the true ecological importance of this phenomenon is still being realized. Members of the family Vespidae interact with honey bees via predation or through the robbing of brood or honey from colonies, and these activities could result in virus transfer. In this study we screened Vespa velutina and Vespa crabro collected from Europe and China and also honey bees and Vespula vulgaris from the UK for Moku virus (MV), an Iflavirus first discovered in the predatory social wasp Vespula pensylvanica in Hawaii. MV was found in 71% of Vespula vulgaris screened and was also detected in UK Vespa crabro. Only seven percent of Vespa velutina individuals screened were MV-positive and these were exclusively samples from Jersey. Of 69 honey bee colonies screened, 43% tested positive for MV. MV replication was confirmed in Apis mellifera and Vespidae species, being most frequently detected in Vespula vulgaris. MV sequences from the UK were most similar to MV from Vespula pensylvanica compared to MV from Vespa velutina in Belgium. The implications of the transfer of viruses between the Vespidae and honey bees are discussed.

Flower Visiting

We quantified insect visitation rates by counting how many flowers/inflorescences were probed per unit time for five plant species (four native and one garden: California lilac, bramble, ragwort, wild marjoram, and ivy) growing in Sussex, United Kingdom, by following individual insects (n=2987) from nine functional groups (honey bees (Apis mellifera), bumble bees (Bombusspp.), hoverflies, flies, butterflies, beetles, wasps, non-Apidae bees, and moths). Additionally, we made a census of the insect diversity on the studied plant species. Overall we found that insect groups differed greatly in their rate of flower visits (P<2.2e-16), with bumble bees and honey bees visiting significantly more flowers per time (11.5 and 9.2 flowers/minute, resp.) than the other insect groups. Additionally, we report on a within-group difference in the non-Apidae bees, where the genusOsmia, which is often suggested as an alternative to honey bees as a managed pollinator, was very speedy (13.4 flowers/minute) compared to the other non-Apidae bees (4.3 flowers/minute). Our census showed that the plants attracted a range of insects, with the honey bee as the most abundant visitor (34%). Therefore, rate differences cannot be explained by particular specializations. Lastly, we discuss potential implications of our conclusions for pollination.

Resumen El objetivo de este trabajo es doble. En primer lugar, estudiamos la figura y la obra del médico y naturalista Ángel Guirao Navarro al frente del Instituto Provincial de Segunda Enseñanza de Murcia. Este polifacético profesor tuvo un importante rol en el desarrollo de los espacios escolares para la enseñanza práctica de la Historia Natural, dándoles contenido con la aportación de objetos naturales recolectados por él o adquiridos por el Instituto. También analizamos los materiales de apoyo para esa enseñanza como: los libros de texto, el herbario y las láminas de pared. Por otro lado, estudiamos el espacio utilizado para la enseñanza práctica de la Botánica y la Agricultura. El papel de Ángel Guirao en el desarrollo del Jardín Botánico fue clave para que este se convirtiera en uno de los jardines educativos más completos de España con la construcción de invernaderos de cristal, umbráculos, pabellón docente y la adquisición de plantas y semillas facilitadas por el Jardín Botánico de Valencia, el Real Jardín Botánico de Madrid y el Instituto Agronómico de la Moncloa. Abstract The goal of this paper is twofold. First, we study the figure and work of the medicine doctor and naturalist Ángel Guirao Navarro, head of the Secondary School of Murcia. This versatile teacher played an important role in the development of scholar spaces for the practical teaching of Natural History by contributing with natural objects collected by him or acquired by the Secondary School of Murcia. We also analyse the pedagogical materials for this teaching such as: textbooks, herbarium and wall papers. On the other hand, we study the space used for the practical teaching of botany and agriculture. The role of Ángel Guirao in the development of the Botanical Garden was key for it to become one of the most complete educative gardens of Spain with the construction of glass greenhouses, shade structures, one teaching pavilion, as well as the acquisition of plants and seeds provided by the Botanical Garden of Valencia, the Royal Botanic Garden of Madrid and the Agronomic Institute of La Moncloa.

Nutritional Effect

AbstractAlpha-linolenic acid (ALA), which is an n-3 polyunsaturated fatty acid (PUFA), influences honey bee feed intake and longevity. The objective of this study was to research the effect of six dietary ALA levels on the growth and development of Apis mellifera ligustica colonies. In the early spring, a total of 36 honey bee colonies of equal size and queen quality were randomly allocated into 6 groups. The six groups of honey bees were fed a basal diet with supplementation of ALA levels at 0 (group A), 2 (group B), 4 (group C), 6 (group D), 8 (group E), and 10% (group F). In this study, there were significant effects of pollen substitute ALA levels on the feeding amounts of the bee colony, colony population, sealed brood amount, and weight of newly emerged workers (P<0.05). The workers’ midgut Lipase (LPS) activity of group C was significantly lower than that of the other groups (P<0.01). The worker bees in groups B, C, and D had significantly longer lifespans than those in the other groups (P<0.05). However, when the diets had ALA concentrations of more than 6%, the mortality of the honey bees increased (P<0.01). These results indicate that ALA levels of 2 ~ 4% of the pollen substitute were optimal for maintaining the highest reproductive performance and the digestion and absorption of fatty acids in honey bees during the period of spring multiplication. Additionally, ALA levels of 2 ~ 6% of the pollen substitute, improved worker bee longevity.

The kinetic parameters of trehaiase in honey bee and flesh fly mitochondria were compared. The studies were carried out with whole mitochondria and with mitochondria disrupted in various ways and to different degrees. Honey bee mitochondrial trehalase was significantly activated by Lubrol WX treatment (30.0-fold), by high pH treatment (20.8-fold), and by a treatment consisting of 10 passes through a French press (37.9-fold) but not by the other treatments tried (salt, proteases, Waring blender, and sonication), despite the fact that these treatments also disrupted the mitochondria significantly. The activation effect was on the Vmax. The Km value did not change. Simple breakage of either the outer or inner (or both) membranes was not sufficient to activate trehalase from honey bees, which showed that the activation was not an indirect result of a change in the ease with which trehalose can pass through the membranes. Honey bee trehalase is the first trehalase from insects with asynchronous muscle which has been shown to be activatable by physical and chemical methods. Flesh fly mitochondrial trehalase behaved quite differently from the honey bee enzyme in that it could not be activated by any of the techniques tried, even when there were significant amounts of disruption.
