Legwaila1, Motshwari Obopile2 and Bamphitlhi Tiroesele2* 1Botswana National Museum, Box 00114, Gaborone, Botswana. 2Botswana University of Agriculture and Natural Resources, P/Bag 00114, Gaborone, Botswana. Received 13 April, 2021; Accepted 16 July, 2021 The carmine spider mite (CSM; Tetranychus cinnabarinus Bois.) is one of the most destructive pests of vegetables, especially tomatoes. Its management in Botswana has, for years, relied on the use of pesticides. This study evaluated the efficacy of abamectin, methomyl and chlorfenapyr against CSM eggs under laboratory conditions in Botswana. Each treatment was replicated three times. The toxic effect was evaluated in the laboratory bioassay after 24, 48 and 72 h of application of pesticides. This study revealed that chlorfenapyr was relatively more effective since it had lower LD50 values than those for abamectin and methomyl. It was further revealed that at recommended rates, 90% mortalities occurred 48 h after application of methomyl and chlorfenapyr, while abamectin did not achieve 90% mortality throughout the study period. This implies that abamectin requires extra dosages to achieve mortalities comparable to those of the other two pesticides. The study has found that chlorfenapyr was the most effective insecticide followed by methomyl and then abamectin when applied on CSM eggs. -

Status of Beekeeping in Ethiopia- a Review
Journal of Dairy & Veterinary Sciences ISSN: 2573-2196 Review Article Dairy and Vet Sci J Volume 8 Issue 4 - December 2018 Copyright © All rights are reserved by Kenesa Teferi DOI: 10.19080/JDVS.2018.08.555743 Status of Beekeeping in Ethiopia- A Review Kenesa Teferi* College of Veterinary Medicine, Mekelle University, Ethiopia Submission: November 16, 2018; Published: December 06, 2018 *Corresponding author: Kenesa Teferi, College of Veterinary Medicine, Mekelle University, Ethiopia Summary Beekeeping practices is an oldest agricultural activity in Ethiopia. It is a major integral component in agricultural economy of the country. It contributes to the economy of the country directly and indirectly. Its direct contributions are collection of the honey and hive products such as bees wax, and bee colonies whereas its indirect contributions are increase in crop production and conservation of the natural environment through pollination. Despite all the potentials the subsector can offer, the apiculture in Ethiopia has suffered from under estimation of its potential and its role for socioeconomic development. The country’s potential for honey and beeswax production is expected to be 500,000 and 50, 000 tons per year for honey and beeswax respectively, but only approximately about 10% of the honey and wax potential have been tapped, and the commercialization of other high value bee products such as pollen, propolis and bee venom is not yet practiced at a marketable volume, even not yet recognized. Ethiopia ranks ninth in honey and third in beeswax production in the world. All regions of Ethiopia produce honey, but their production potential is different based on suitability of the regions for beekeeping i.e., density of bee’s forages across the region is different and the techniques varies also. -

My research focuses on Nature’s most celebrated architects — bees — and their architectural masterpiece — the honeycomb. Bee honeycombs are wax-made cellular structures of hexagonal prismatic geometries. Within the comb, bees form their nests, grow their larvae, and store honey and pollen. They operate as a “social womb” informed, at once, by communal (genetic) makeup and environmental forces. Resource sharing, labor division, and unique communication methods all contribute to the magic that is the bee “Utopia.” Given that the geometrical, structural, and material make up of honeycombs is informed by the environment, these structures act as environmental footprints, revealing, as a time capsule, the history of its external environment and factors. -

DECEMBER 2018 TREE of the MONTH Scarlet Oak ● Quercus Coccinea RED OAK • BLACK OAK • SPANISH OAK
DECEMBER 2018 TREE OF THE MONTH Scarlet Oak ● Quercus coccinea RED OAK • BLACK OAK • SPANISH OAK Scarlet oak is a medium-sized tree native to eastern and central North America. Scarlet oaks are popular landscape trees because of their fast growth and brilliant autumn color. Scarlet oak grows on sandy and acidic soils, reaching 20-30 meters in height with an open, rounded crown and an alternate branching pattern. Scarlet oaks are fast-growing, shade-intolerant trees that often associate with black oaks (Quercus velutina) and red oaks (Quercus rubra). OPPOSITE BRANCHING PATTERN ALTERNATE BRANCHING PATTERN POINTY LEAVES The leaves are shiny with deep, rounded sinuses, and each lobe has three teeth on the 6p. The leaves turn bright scarlet in autumn. Characteris6cally for oaks, the buds are clustered around the terminal bud at the end of the twig. Each bud is covered with whi6sh hairs on the upper half. The inner bark is pinkish brown and, unusually for oaks, is not bi>er. SPRING BLOOMERS Scarlet oaks Mlower in mid-spring, often May, and bear drooping male catkins (clusters) and female Mlowers singly or in groups of two or three. Acorns develop later in the season in singles or pairs and drop in late Autumn. FOOD FOR ALL Scarlet oak acorns are popular for many wildlife species, from squirrels, mice, and chipmunks, to deer, wild turkeys, and woodpeckers, and jays. TRICKY FELLOW Quercus coccinea is often be confused with the northern red oak (Quercus rubra), black oak (Quercus velutina) and pin oak (Quercus palustris).

Honey Bee from Wikipedia, the Free Encyclopedia
Honey bee From Wikipedia, the free encyclopedia A honey bee (or honeybee) is any member of the genus Apis, primarily distinguished by the production and storage of honey and the Honey bees construction of perennial, colonial nests from wax. Currently, only seven Temporal range: Oligocene–Recent species of honey bee are recognized, with a total of 44 subspecies,[1] PreЄ Є O S D C P T J K Pg N though historically six to eleven species are recognized. The best known honey bee is the Western honey bee which has been domesticated for honey production and crop pollination. Honey bees represent only a small fraction of the roughly 20,000 known species of bees.[2] Some other types of related bees produce and store honey, including the stingless honey bees, but only members of the genus Apis are true honey bees. The study of bees, which includes the study of honey bees, is known as melittology.

Carmine , C.I. 75470
CARMINE , C.I. 75470 IVD In vitro diagnostic medical device Natural Red 4, Cochineal, Nacarat, aluminum and carminic acid compound For staining mucicarmine and glycogen INSTRUCTIONS FOR USE REF Product code: CAR-P-5 (5 g) CAR-P-10 (10 g) CAR-P-25 (25 g) Introduction Histology, cytology and other related scientific disciplines study the microscopic anatomy of tissues and cells. In order to achieve a good tissue and cellular structure, the samples need to be stained in a correct manner. Carmine is a natural dye whose structure has not been fully explored. However, it is known that it contains aluminum ions, calcium ions to lesser extent, proteins and sometimes silicon. It is often bound with lithium, aluminum or boron to form a complex in order to achieve satisfactory staining results. Carmine is used for various staining procedures and visualization of glycogen and mucous substances, as well as for nuclear staining and vital staining. Product description CARMINE - Powder dye for making solution for histology staining Example of use of Carmine powder dye for detecting glycogen Other sections and reagents that are used in the staining method: absolute ethyl alcohol, methanol potassium chloride, potassium carbonate ammonia Hematoxylin ML Preparing the solutions for staining 1. Carmine stock solution Dissolve 2 g of Carmine powder dye and 5 g of potassium chloride in 60 mL of distilled water while heating the mixture. Add 1 g of potassium carbonate and let it slowly boil (the mixture produces excessive amount of foam). Let it boil for a few minutes as the color changes to dark red.
