Morphological aspects of cell reabsorption in laying queens and workers of Apis mellifera (Hymenoptera, Apidae)
The occurrence of cell reabsorption in the ovaries of queens in several rates of laying eggs, artificially impeded of laying, and in nurse workers, of Apis mellifera (Linnaeus, 1758), was studied with light (LM) and transmission electron microscopy (TEM). Two types of structures were described and named by analogy with vertebrates ovarian structures, as corpus luteus, when resulting from the re...
متن کاملIsolation and Identification of Biologically Active Components from the Honey Bee Venom Apis Mellifera L. Caucasica
The venom of the European honey bee Apis mellifera is an intricate mixture of chemical compositions, including proteins, peptides, enzymes, and other small molecules. Lately, there has been growing interest in the use of melittin, due to its wide range of biological and potential therapeutic applications. Melittin, which is considered to be an antimicrobial, antitumor, and antiinflammatory pept...
متن کاملMorphometric Identification of Queens, Workers and Intermediates in In Vitro Reared Honey Bees (Apis mellifera)
In vitro rearing is an important and useful tool for honey bee (Apis mellifera L.) studies. However, it often results in intercastes between queens and workers, which are normally are not seen in hive-reared bees, except when larvae older than three days are grafted for queen rearing. Morphological classification (queen versus worker or intercastes) of bees produced by this method can be subjec...
متن کاملFlavonoids from Apis mellifera Beeswax
The flavonoids present in beeswax produced in “La Alcarria” region were analyzed by HPLC. Pinocembrin, pinobanksin, pinobanksin 3-acetate, chrysin, galangin and techtochrysin were detected as the main flavonoid constituents. This is the first detailed report on the flavonoids o f beeswax. These substances are already present when wax scales are secreted by bees. The same flavonoid compounds wer...
متن کاملDifferential gene expression between developing queens and workers in the honey bee, Apis mellifera.
Many insects show polyphenisms, or alternative morphologies, which are based on differential gene expression rather than genetic polymorphism. Queens and workers are alternative forms of the adult female honey bee and represent one of the best known examples of insect polyphenism. Hormonal regulation of caste determination in honey bees has been studied in detail, but little is known about the ...
