Honeybees are one of the most marvelous and economically beneficial insects. As pollinators, they play a vital role in every aspect of the ecosystem. Beehive products have been used for thousands of years in many cultures for the treatment of various diseases. Their healing properties have been documented in many religious texts like the Noble Quran and the Holy Bible. Honey, bee venom, propolis, pollen and royal jelly all demonstrated a richness in their bioactive compounds which make them effective against a variety of bacterial strains. Furthermore, many studies showed that honey and bee venom work as powerful antibacterial agents against a wide range of bacteria including life-threatening bacteria. Several reports documented the biological activities of honeybee products but none of them emphasized on the antibacterial activity of all beehive products. Therefore, this review aims to highlight the antibacterial activity of honey, bee venom, propolis, pollen and royal jelly, that are produced by honeybees.

Honey Bee Mating Optimization

Abstrak Vahicle Routing Problem adalah suatu masalah pencaian jalur yang akan dilalui dengan tujuan mencari rute yang paling cepat atau pendek. Vahicle Routing Problem with Time Windows (VRPTW) yang merupakan sebutan bagi VRP dengan kendala tambahan berupa adanya time windows pada masing-masing pelanggan yang dalam hal ini berupa destinasi wisata. Dalam penelitian ini diterapkan Honey Bee Mating Optimization (HBMO) dalam menyelesaikan VRPTW. HBMO sendiri terinspirasi oleh perilaku koloni lebah ketika bereproduksi. Algoritma tersebut bertujuan untuk mengevaluasi pencarian individu atau solusi terbaik. Tujuan dari penelitian ini adalah bagaimana mengimplementasikan Honey Bee Mating Optimization dalam menyelesaikan VRPTW pada perencanaan jalur wisata di Malang. Sehingga dapat meminimumkan waktu dan jarak tempuh perjalanan. Berdasarkan hasil pengujian, parameter yang optimal untuk optimasi VRPTW menggunakan HBMO pada kasus perencannan jalur wisata Malang yaitu dengan menggunakan 800 generasi, populasi lebah jantan sebesar 300, batas kapasitas spermatheca sejumlah 100, nilai mutation ratio (Pm) dan royal jelly masing-masing bernilai 0.5.Abstract Vahicle Routing Problem is a problem of finding the best route that will be passed with the purpose to finding the fastest or shortest route. Vahicle Routing Problem with Time Windows (VRPTW) is a part of VRP with additional obstacles in the form of time windows in each customer. In this research, Honey Bee Mating Optimization (HBMO) was applied to completing VRPTW. HBMO itself was inspired by the behavior of bee colonies when reproducing. The purpose of this algorithm is to evaluate the best individual or the best solutions. The purpose of this research is how to implement Honey Bee Mating Optimization to completing VRPTW in Malang tourism route planning. So that it can minimize travel time and distance. Based on the results of the testing, the optimal parameters for VRPTW optimization using HBMO in Malang tourism route planning case are using 800 generations, the male bee population is 300, the capacity limit of spermatheca is 100, the mutation ratio (Pm) and royal jelly are respectively 0.5.

Gene Expression Dynamics

One of the first tasks of worker honey bees (Apis mellifera) during their lifetime is to feed the larval offspring. In brief, young workers (nurse bees) secrete a special food jelly that contains a large amount of unique major royal jelly proteins (MRJPs). The regulation of mrjp gene expression is not well understood, but the large upregulation in well-fed nurse bees suggests a tight repression until, or a massive induction upon, hatching of the adult worker bees. The lipoprotein vitellogenin, the synthesis of which is regulated by the two systemic hormones 20-hydroxyecdysone and juvenile hormone, is thought to be a precursor for the production of MRJPs. Thus, the regulation of mrjp expression by the said systemic hormones is likely. This study focusses on the role of 20-hydroxyecdysone by elucidating its effect on mrjp gene expression dynamics. Specifically, we tested whether 20-hydroxyecdysone displayed differential effects on various mrjps. We found that the expression of the mrjps (mrjp1–3) that were finally secreted in large amounts into the food jelly, in particular, were down regulated by 20-hydroxyecdysone treatment, with mrjp3 showing the highest repression value.
