Provedor de dados: 80
Autores: Mughal,Mudassar Niaz; Abbas,Ghazanfar; Saqib,Muhammad; Muhammad,Ghulam.
In the present study, a fatal case caused by honeybee (Apis cerana) stings was documented in a female German shepherd dog that was presented at the Veterinary Teaching Hospital, University of Agriculture Faisalabad, Pakistan. Characteristic clinical signs included hematuria, hematemesis, incoordination and convulsions along with evidence of massive honeybee attack supported the diagnosis of envenomation. The dog was treated with dexamethasone and diphenhydramine, but it did not respond to therapy and died. This outcome could be avoided if we had a bee antivenom available for treating envenomated patients.

Resistance to Chalkbrood Disease in Apis mellifera L. (Hymenoptera: Apidae) Colonies with Different Hygienic Behaviour
Provedor de dados: 82
Autores: Invernizzi,C; Rivas,F; Bettucci,L.
Chalkbrood disease affects the larvae of honeybees Apis mellifera L. and is caused by the fungus Ascosphaera apis. Infected larvae die when they are stretched in the cap cell and suffer a gradual hardening that ends in a very hard structure (mummie). Several studies have demonstrated that colonies that express an efficient hygienic behaviour (uncapping of cell and subsequent removal of dead brood) exhibit a higher resistance to the disease. However, it remains unclear whether the advantage of hygienic colonies over less hygienic ones lies in the ability to remove mummies or in the early detection of infected larvae and its cannibalization before they harden. To elucidate this aspect, the hygienic behaviour of 24 colonies, which were subsequently provided...

　銀ナノ粒子・基板を用い，みつばち体表に付着している農薬のクロチアニジン（Clothianidin） のラマンスペクトル（表面増強ラマンスペクトル，Surface Enhanced Raman Spectrum：SERS）に よる検出・測定を行った。北海道の上川支庁管内（旭川市近郊）で採取したみつばち試料等の殆ど からクロチアニジンが検出され，みつばちが約1～4ng/ 匹のクロチアニジンに暴露されているこ とが明らかにされた。この結果から，同農薬がみつばちの健康に影響を与えている可能性が示唆 された。 We conducted experiments to detect clothianidin on body surface of honey bee using silver　nanoparticlesubstrate by surface enhanced Raman spectroscopy (SERS). Most of the honey bee samples, collected from bee hives near Kamikawa area in Hokkaido, were exposed to about 1 to 4 ng clothianidin / bee on body surface. These results suggest that clothianidin residue found on body surface possibly affect the health of honey bee colonies.

Expression profile of a Laccase2 encoding gene during the metamorphic molt in Apis mellifera (Hymenoptera,Apidae)
Provedor de dados: 92
Autores: Elias-Neto,Moysés; Soares,Michelle P.M.; Bitondi,Márcia M. G.
Expression profile of a Laccase2 encoding gene during the metamorphic molt in Apis mellifera (Hymenoptera, Apidae). Metamorphosis in holometabolous insects occurs through two subsequent molting cycles: pupation (metamorphic molt) and adult differentiation (imaginal molt). The imaginal molt in Apis mellifera L. was recently investigated in both histological and physiological-molecular approaches. Although the metamorphic molt in this model bee is extremely important to development, it is not well-known yet. In the current study we used this stage as an ontogenetic scenario to investigate the transcriptional profile of the gene Amlac2, which encodes a laccase with an essential role in cuticle differentiation. Amlac2 expression in epidermis was contrasted...

Detección de Malpighamoeba mellifcae (Protista: Amoebozoa) en Apis mellifera (Hymenoptera: Apidae)de Argentina
Provedor de dados: 99
Autores: Plischuk,Santiago; Lange,Carlos E.
Debido a su rol como polinizador y productor de miel, la abeja Apis mellifera L. es considerado un insecto beneficioso. Si bien Argentina juega un papel de liderazgo en la producción de miel, existe un considerable vacío en el conocimiento acerca de las enfermedades de etiología protista que afectan las abejas en el país. La ameba Malpighamoeba mellificae Prell es un protista entomopatógeno que invade los túbulos de Malpighi de las abejas e interfiere con el proceso de excreción, debilitando al huésped y posiblemente facilitando la acción de otros patógenos. En esta contribución se presentan los primeros hallazgos de M. mellificae en Argentina y se brindan datos iniciales acerca de su frecuencia, intensidad de las infecciones, y co-ocurrencia con Nosema...

Honey bee as an effective pollinating agent of pumpkin
Provedor de dados: 63
Autores: Nicodemo,Daniel; Couto,Regina Helena Nogueira; Malheiros,Euclides Braga; De Jong,David.
The production of fruits and seeds of many crops is increased when bees visit their flowers pollinating them. The aim of this research was to study the pollination of pumpkins (Cucurbita maxima Duch. var. Exposição), to determine the diversity of insects visiting its flowers, the time and type of provision obtained and the effect of the visits on fruit set, fruit size and weight, and number of seeds. Apis mellifera L. accounted for 73.4% of the visits made by bees, collecting pollen during 34.5 s per flower and nectar in 43.9 s and 29.3 s from female and male flowers, respectively. Trigona spinipes (Fabr.) collected only nectar, during a mean time of 60.5 s per flower, and represented 26.6% of the visits by bees. Diabrotica speciosa (Germ.) only fed on the...

Insect juvenile hormone: from "status quo" to high society
Provedor de dados: 56
Autores: Hartfelder,K.
Juvenile hormone (JH) exerts pleiotropic functions during insect life cycles. The regulation of JH biosynthesis by neuropeptides and biogenic amines, as well as the transport of JH by specific binding proteins is now well understood. In contrast, comprehending its mode of action on target organs is still hampered by the difficulties in isolating specific receptors. In concert with ecdysteroids, JH orchestrates molting and metamorphosis, and its modulatory function in molting processes has gained it the attribute "status quo" hormone. Whereas the metamorphic role of JH appears to have been widely conserved, its role in reproduction has been subject to many modifications. In many species, JH stimulates vitellogenin synthesis and uptake. In mosquitoes,...
