The Small hive beetle (Aethina tumida), the large ٪٠٫٥٤٣ hive beetle (Hyplostoma fuligineus) and the Bee wolf (Palarus latifrons) were recorded for the first time in Sudan. Some insects such as Earwigs Silverfish, Cockroaches, Praying Mantids, Dragonflies, Termites, Locust, Dwarf bee (Apis florea) and the sting less bees were also reported as a pest of honeybees The major mammalian pests that found in Sudan were Man (honey hunters), Livestock (Cattle and Camels), Squirrel and Honeybadger (Mellivora capensis). The last one was reported as a pest of honeybee colonies in Sudan in this study for the first time. The bee-eaters birds of honeybee colonies were: Merops apiaster, M.nubicus, M.albicolus, M.orientalis and M.pusilus. The honey guide Indicator indicator and the ground hornbill Bucorvus abyssinicus were recorded as a pest of honeybee colonies for the first time in Sudan.

  • The Sphingidae (Lepidoptera) of the Philippines
    ©Entomologischer Verein Apollo e.V. Frankfurt am Main; download unter www.zobodat.at Nachr. entomol. Ver. Apollo, Suppl. 17: 17-132 (1998) 17 The Sphingidae (Lepidoptera) of the Philippines Willem H o g e n e s and Colin G. T r e a d a w a y Willem Hogenes, Zoologisch Museum Amsterdam, Afd. Entomologie, Plantage Middenlaan 64, NL-1018 DH Amsterdam, The Netherlands Colin G. T readaway, Entomologie II, Forschungsinstitut Senckenberg, Senckenberganlage 25, D-60325 Frankfurt am Main, Germany Abstract: This publication covers all Sphingidae known from the Philippines at this time in the form of an annotated checklist. (A concise checklist of the species can be found in Table 4, page 120.) Distribution maps are included as well as 18 colour plates covering all but one species. Where no specimens of a particular spe­ cies from the Philippines were available to us, illustrations are given of specimens from outside the Philippines. In total we have listed 117 species (with 5 additional subspecies where more than one subspecies of a species exists in the Philippines). Four tables are provided: 1) a breakdown of the number of species and endemic species/subspecies for each subfamily, tribe and genus of Philippine Sphingidae; 2) an evaluation of the number of species as well as endemic species/subspecies per island for the nine largest islands of the Philippines plus one small island group for comparison; 3) an evaluation of the Sphingidae endemicity for each of Vane-Wright’s (1990) faunal regions. From these tables it can be readily deduced that the highest species counts can be encountered on the islands of Palawan (73 species), Luzon (72), Mindanao, Leyte and Negros (62 each).

  • Epigaeic Invertebrate Community Structure in Two Subtropical Nature Reserves, Eastern Cape, South Africa: Implications for Conservation Management
    © Arachnologische Gesellschaft e.V. Frankfurt/Main; http://arages.de/ Arachnologische Mitteilungen / Arachnology Letters 52: 7-15 Karlsruhe, September 2016 Epigaeic invertebrate community structure in two subtropical nature reserves, Eastern Cape, South Africa: Implications for conservation management Augustine S. Niba & Inam Yekwayo doi: 10.5431/aramit5203 Abstract. Epigaeic invertebrates were sampled at non-invaded (‘Indigenous Forest’ and ‘Indigenous Grassland’) and alien-invaded (‘Eu- calyptus’ and ‘Mixed alien’) sub-sites in the Nduli and Luchaba Nature Reserves using pitfall traps. A total of 2054 specimens belonging to three phyla (Arthropoda, Mollusca and Annelida) was caught and sorted into seven orders, 18 families, one tribe, 45 genera (22 identified to species level) and 20 morphospecies. Higher species richness occurred in ‘Indigenous Forest’ and ‘Mixed Alien’ sub-sites while higher specimen counts were made in invaded (‘Mixed Alien’ and ‘Eucalyptus’) sub-sites during summer months, peaking in January. Canonical Correspondence Analysis results show that some measured site variables, e.g. litter depth, grazing intensity, percentage of alien vege- tation cover, and soil chemical properties accounted for invertebrate taxa composition and distribution trends at sub-sites. Although habitat-patch level characteristics (including abiotic factors) were important for determining species distributions, increased levels of infestation by invasive alien vegetation across sub-sites did not necessarily impact on epigaeic invertebrates

  • Effectiveness of Three Pesticides Against Carmine Spider Mite (Tetranychus Cinnabarinus Boisduval) Eggs on Tomato in Botswana
    Vol. 17(8), pp. 1088-xxx, August, 2021 DOI: 10.5897/AJAR2021.15591 Article Number: 3489C4F67485 ISSN: 1991-637X Copyright ©2021 African Journal of Agricultural Author(s) retain the copyright of this article http://www.academicjournals.org/AJAR Research Full Length Research Paper Effectiveness of three pesticides against carmine spider mite (Tetranychus cinnabarinus Boisduval) eggs on tomato in Botswana Mitch M. 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.

Gupta Jawahar Lal Nehru Krishi Vishwavidyalaya, Department of Entomology, College of Agriculture, Tikamgarh-472 001 M.P., India. (#e-mail: [email protected]) Abstract The bioecology of til hawk moth, Acherontia styx Westwood was studied on Sesamum indicum (Linn.) variety TKG-22 under field and lab. condition during 2004-06. The eggs were globular in shape, yellow in colour with 0.70-0.95 mm in size. The incubation period of the eggs was 2-4 days with the neonate period of 10-15 minutes. There were five larval instars and length of the completely developed larva was 68-79 mm with larval period of 20-21 days. The maximum larvae were obtained during late August to September. The pre-pupal and pupal periods were 3-4 and 14-23 days respectively, with pupae conical in shape. The mating was always at morning (0.07-0.10 minutes) followed by oviposition (24 to 36 hours) with fecundity of 5-8. Life span of the adult was 3-5 days, total life cycle was completed in 39-52 days. Mean adult emergence (%), sex ratio and growth index were 95 to 100%, 1:1 and 2.64 to 2.27 respectively. There are only three generations in a year. The plants were infested to the extent of 31.6% by this insect. Maximum damage is caused during September-October. Keywords: Bioecology, Acherontia styx Westwood. Introduction Sesame Sesamum indicum Linn. is the Materials and Methods oldest indigenous oilseed crop of the world and Studies on the bionomics of til hawk moth, also a major oilseed crop of India.

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.

  • 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). Tree of the Month is a collabora1on between BEAT, the City of Pi:sfield and Pi:sfield Tree Watch.
