    Varietal and planting date effects on damage by the gall midge, Asphondylia sesame, to sesame was investigated in small plot tests conducted at Lafia, Nigeria, in 2007 and 2008. Three dates of planting, July 26, August 3 and August 10, as main plot treatments, and an early-maturing variety [90 days] variety of sesame, E-8, and a late-maturing one [120 days] Yandev-55, as subplot treatments, were replicated four times in randomized complete block design. Over the two years, incidence of galling ranged from 4.2-17.5% (mean = 11.54%) and it explained 66.6% of the variation in seed yield. The earliest- planted plots were the most productive in terms of number of pods (mean = 789.8/5 plants), seed yield (mean = 175.0 kglha), and were the least damaged (4.25% galling incidence). One to two weeks delay in planting caused 22.1-34.1 % reduction in podding, 39.1-45.1 % reduction in seed yield, and it increased galling incidence by 171.8-305.9%. Varietal differences were significant (P0.05). Galling incidence was >2-fold lower and seed yield 1.8-fold higher on Variety E-8 than on Yandev-45. Early planting of E-8 is recommended as a sustainable way of mitigating gall midge damage to sesame.

    Globalization and Pest Control: Equipping Nigerian Entomologists for Global Impact
    (Department of Agronomy, Nasarawa State University Keffi, 2015-05-04) Ogunwolu, E.O.; Ajayi, Folorunso A.; Nwosu, L.C.
    Globalization is defined as the integration of economic, political, and cultural systems around the world and it is recognized as a force for economic growth. It is powerfully driven by advances in science and technology, information and communication technology, anthropogenic activities of which the most dynamically expanding in frontiers are commerce, tourism, and humanitarian aids. As a consequence, trans-boundary insect pest species are increasing. We enumerate the consequences, economic, ecological and environmental impacts of insect pests on a global scale and posit that the competitiveness ofthe Nigerian Entomologist as a key player in the knowledge economy that drives national and international trade policies and regulations, national, regional, international pest management programmes is still at a very low ebb. To equip the Nigerian Entomologist for global impact requires designing educational programmes to enhance ability to shape, evaluate and implement policies designed to mitigate challenges of globalization; build both research and management capacity; strengthen and make more impactful contributions to national, regional, and international legal framework on phytosanitation; create and uphold public awareness; and promote international co-operation. We advocate commencement of an Entomology 1st degree programme premised on education for knowledge-driven development and entrepreneurship. Furthermore, the National Executive Council of the Entomological Society of Nigeria is urged to expedite action on the legal frameworkrequired to establish the Nigerian Institute of Entomology for the regulation and control ofthe
