R. A. Asco ................................................................... 317 Conclusions and Recommendations ..................................... 331 IV Preface In many countries of the world, agricultural plant protection relies heavily on pesticides. While providing effective control, chemical pesticides have produced major well known problems : health hazards to humans and animals, destruction of natural biotic control agents and increased resistance of major insects species and steady increase in dosages required to control them. In spite of a more than 10 fold increase insecticide use since 1940, crop losses due to insects have nearly doubled in the same period. This situation accelerates the movement towards more sound control methods of which the microbial control proved to be the most efficient. The most promising biological agent to date to satisfy this goal is the bacterium Bacillus thuringiensis (B. t. ). This organism proved to be a highly successful weapon for fighting some agricultural pests and some vectors of diseases but its use is still limited in developing countries except China where it is widely produced and used. It is non toxic to people, most other non target insects and the environment. It can be targeted to specific pests. The safety ofB. t. is associated with a much lower development cost, in large part due to the reduced expenses of obtaining registration. Plans have been made to organise "The International workshop on Bacillus thuringiensis (B.t.) and its application as it relates to developing countries "at the National Research Centre (NRC), Cairo, Egypt, from November 4 - 6, 1991. This workshop was organized jointly by the National Research Centre, the International Development Research Centre, IDRC, Ottawa and Agriculture Canada, Winnipeg, Manitoba. The objectives of the workshop were as follows : 1. Identifying the constraints facing increased utilization of B. t. in developing countries. 2. Discussing recent research on specific topics as they relate to developing countries. 3. Identifying needs and priorities for the increased utilization of B. t. in developing countries. This volume provides a comprehensive coverage of the present and potential use of Bacillus thuringiensis in developing countries. It aims to collate the existing

Recently, Helicoverpa zea (Boddie) (Lepidoptera: Noctuidae) has developed resistance to two toxin Bt maize and cotton (Cry1A and Cry2A). Hence, growers are transitioning to three toxin Bt cotton and maize that express both Cry toxins and the Vip3Aa toxin. H. zea susceptibility to Vip3Aa is threatened by 1) a lack of availability of non-Bt refuge crop hosts, including a 1–5% annual decline in the number of non-Bt maize hybrids being marketed; 2) the ineffectiveness of three toxin cultivars to function as pyramids in some regions, with resistance to two out of three toxins in the pyramid; and 3) the lack of a high dose Vip3Aa event in cotton and maize. We propose that data should be collected on current Cry-resistant H.

Seasonal distribution of moths of the Koakoland (Mopane) Savanna in Ogongo, northern Namibia Grzegorz KOPIJ Department of Wildlife Management, University of Namibia, Katima Mulilio Campus, Private Bag 1096, Katima Mulilo, Namibia; e-mail: [email protected] Abstract: During the years 2011–2013, moths were collected in Koakoland (Mopane) Savanna in the Cuvelai Drainage System, Ovamboland, northern Namibia. In total, 77 species from 13 families have been identified. Their seasonal occurrence in this habitat was also investigated, with most species recorded in wet season between September and April, but with clear peak in February and March. The family Noctuidae was by far the most speciose (38 recorded species), followed by Crambidae (8 spp.), Sphingidae (6 spp.) and Arctiidae (4 spp.). All other families were represented by 1–3 species. For each species listed date of collection is given, and data on its global distribution. Key words: Lepidoptera, check-list, biodiversity, distribution, moths, Ovamboland INTRODUCTION According to recent quite precise estimate, there are 15 5181 species, 16 650 genera and 121 families of Lepidoptera worldwide (Pouge 2009). Lepidoptera fauna of Namibia has recently attracted attention of European entomologists. However, thorough surveys were conducted hitherto in a few areas only, such as Brandberg and Hobatere. The northern regions of the country were especially badly neglected. In southern Africa (south of Zambezi and Kunene Rivers) – 8 511 species, 2 368 genera and 89 families were recently catalogued (Vári et al.

Some differentiated cell types display cooperative behaviour. Cooperation is one of the greatest mysteries of evolutionary biology and microbes have been considered as an excellent system for experimentally testing evolution theories. Bacillus thuringiensis (Bt) is a spore-forming bacterium, which is genetically closely related to B. anthracis, the agent of anthrax, and to B. cereus, an opportunistic human pathogen. The defining feature that distinguishes Bt from its relatives is its ability to produce crystal inclusions in the sporulating cells.

Additional Contact Information Summary The Environmental Protection Agency (EPA) has conditionally registered a plant-incorporated protectant (PIP) product containing Syngenta Seeds, Incorporated’s (hereafter referred to as Syngenta) new active ingredient, Bacillus thuringiensis Vip3Aa20 insecticidal protein and the genetic material necessary for its production (via elements of vector pNOV1300) in Event MIR162 maize (Organization for Economic Cooperation and Development [OECD] Unique Identifier: SYN-IR162-4). This new product, Bt11 x MIR162 corn (expressing previously registered Cry1Ab and Vip3Aa20, respectively), is intended for commercial distribution and use. The Agency has determined that the use of this pesticide is in the public interest and that it will not cause any unreasonable adverse effects on the environment during the time of conditional registration. The registrant for this product is Syngenta. On August 6, 2008, a tolerance exemption under 40 Code of Federal Regulations (CFR) Part 174 became effective for Vip3Aa proteins, when used as plant-incorporated protectants, in or on corn and cotton (40 CFR § 174.501). The exemption from the requirement of a tolerance for residues of Vip3Aa proteins is inclusive of the Vip3Aa20 insecticidal protein and its use in corn.
