The Damage Caused by Callosobruchus Maculatus On
Research Article Received: 6 May 2015 Revised: 13 November 2015 Accepted article published: 21 January 2016 Published online in Wiley Online Library: 5 April 2016 (wileyonlinelibrary.com) DOI 10.1002/jsfa.7639 The damage caused by Callosobruchus maculatus on cowpea grains is dependent on the plant genotype Elida Barros Torres,a Rafaela S A Nóbrega,b Paulo Ivan Fernandes-Júnior,c Luciana Barboza Silva,a* Gabriel dos Santos Carvalho,a Rita de Cassia Nunes Marinhoa and Bruno E Pavand Abstract BACKGROUND: Beans from cowpea cultivars fertilized with mineral N or inoculated with various rhizobium strains may contain different nitrogen concentrations and nitrogen metabolite composition, which affects the beans’ defense mechanisms against pests. In this study, the population growth of Callosobruchus maculatus reared on beans from four cowpea cultivars fertilized with different nitrogen sources was evaluated. The factors tested were beans from four cowpea cultivars and seven different nitrogen sources: mineral N fertilization, inoculation with five strains of symbiotic diazotrophic bacteria, and soil nitrogen (absolute control). RESULTS: BRS Tapaihum and BRS Acauã cultivars had lower cumulative emergence and instantaneous rate of population growth of the insects compared with other cultivars, indicating antixenosis resistance against C. maculatus. Inoculation of BRS Acauã cultivar with the diazotrophic bacteria strain BR 3299 resulted in higher mortality of C. maculatus. For BRS Tapaihum cultivar, inoculation with diazotrophic bacteria strains BR3267, BR 3262 and BR 3299, and nitrogen fertilization resulted in higher mortality among C. maculatus. CONCLUSION: BRS Tapaihum and BRS Acauã cultivars showed the lowest cumulative insect emergence and instantaneous rates of population growth, and the highest insect mortality, mainly when the grains were obtained from plants inoculated with rhizobial strains. -

II Abstract Selectivity in mate choice and mating behaviour is a central element of sexual selection, and an important component of evolution in a number of species across the animal kingdom. Mate choice relates to how individuals respond to the phenotypic traits of potential mates in order to maximize their own fitness. As most studies on sexual selection concentrate on female mate choice, it is interesting to investigate to what extent male choice may play a role in evolution. -

Jordan Beans RA RMO Dir
Importation of Fresh Beans (Phaseolus vulgaris L.), Shelled or in Pods, from Jordan into the Continental United States A Qualitative, Pathway-Initiated Risk Assessment February 14, 2011 Version 2 Agency Contact: Plant Epidemiology and Risk Analysis Laboratory Center for Plant Health Science and Technology United States Department of Agriculture Animal and Plant Health Inspection Service Plant Protection and Quarantine 1730 Varsity Drive, Suite 300 Raleigh, NC 27606 Pest Risk Assessment for Beans from Jordan Executive Summary In this risk assessment we examined the risks associated with the importation of fresh beans (Phaseolus vulgaris L.), in pods (French, green, snap, and string beans) or shelled, from the Kingdom of Jordan into the continental United States. We developed a list of pests associated with beans (in any country) that occur in Jordan on any host based on scientific literature, previous commodity risk assessments, records of intercepted pests at ports-of-entry, and information from experts on bean production. This is a qualitative risk assessment, as we express estimates of risk in descriptive terms (High, Medium, and Low) rather than numerically in probabilities or frequencies. We identified seven quarantine pests likely to follow the pathway of introduction. We estimated Consequences of Introduction by assessing five elements that reflect the biology and ecology of the pests: climate-host interaction, host range, dispersal potential, economic impact, and environmental impact. We estimated Likelihood of Introduction values by considering both the quantity of the commodity imported annually and the potential for pest introduction and establishment. We summed the Consequences of Introduction and Likelihood of Introduction values to estimate overall Pest Risk Potentials, which describe risk in the absence of mitigation. -

The Beetle Fauna of Dominica, Lesser Antilles (Insecta: Coleoptera): Diversity and Distribution
INSECTA MUNDI, Vol. 20, No. 3-4, September-December, 2006 165 The beetle fauna of Dominica, Lesser Antilles (Insecta: Coleoptera): Diversity and distribution Stewart B. Peck Department of Biology, Carleton University, 1125 Colonel By Drive, Ottawa, Ontario K1S 5B6, Canada stewart_peck@carleton. ca Abstract. The beetle fauna of the island of Dominica is summarized. It is presently known to contain 269 genera, and 361 species (in 42 families), of which 347 are named at a species level. Of these, 62 species are endemic to the island. The other naturally occurring species number 262, and another 23 species are of such wide distribution that they have probably been accidentally introduced and distributed, at least in part, by human activities. Undoubtedly, the actual numbers of species on Dominica are many times higher than now reported. This highlights the poor level of knowledge of the beetles of Dominica and the Lesser Antilles in general. Of the species known to occur elsewhere, the largest numbers are shared with neighboring Guadeloupe (201), and then with South America (126), Puerto Rico (113), Cuba (107), and Mexico-Central America (108). The Antillean island chain probably represents the main avenue of natural overwater dispersal via intermediate stepping-stone islands. The distributional patterns of the species shared with Dominica and elsewhere in the Caribbean suggest stages in a dynamic taxon cycle of species origin, range expansion, distribution contraction, and re-speciation.

The Evolutionary Origin of a Novel Karyotype in Timarcha (Coleoptera, Chrysomelidae) and General Trends of Chromosome Evolution in the Genus

Go´mez-Zurita1,J.Pons2 and E. Petitpierre3,4 Abstract In this work, we have analysed the karyotypes of six species of Timarcha for the first time and updated the cytological information for two additional taxa, for one of them confirming previous results (Timarcha erosa vermiculata), but not for the other (T. scabripennis). We describe the remarkable karyotype of T. aurichalcea, the lowest chromosome number in the genus (2n ¼ 18), distinctive as well for the presence of an unusual chiasmatic sexual bivalent hitherto unreported for Timarcha. This study increases the number of species studied cytologically in this genus to forty. Additional cytogenetic analyses are performed on several species, including Ag-NOR staining and fluorescent in situ hybridization (FISH) studies with ribosomal DNA probes. Karyotype evolution is analysed by tracing different karyotype coding strategies on a published independent phylogenetic hypothesis for Timarcha based on the study of three genetic markers. The implementation of a likelihood model of character change optimized onto the phylogeny is tentatively used to detect possible drifts in chromosome changes. -

Supplementary issue (1996), 22: Citation 29-46 Issue Date 1996-12 URL https://doi.org/10.14989/68378 Right Type Journal Article Textversion publisher Kyoto University African Study Monographs, Supp!. 22: 29 - 46, December 1996 29 ETHNOENTOMOLOGY OF THE CENTRAL KALAHARI SAN Kenichi NONAKA Department of geography, Mie University ABSTRACT The Central Kalahari San use many kinds of insects for daily food and materials and as children's play things. This study describes how several insect species are used, which often follows a series of processes from collecting to consumption and the quite diversified insect utilization based on various skills and knowledge in ethnoento mology. Even though insects are not an important subsistence resource, the San have an extensive knowledge and make good use of insects. The insects even spice up the San daily life. Key words: insects, ethnoentomology, diversified utilization, food, material, children's play INTRODUCTION The San are known to use many kinds of natural resources and possess great knowledge of nature (Lee, 1979; Tanaka, 1980; Silberbauer, 1981). The principle objectives of San studies have focused on the hunting and gathering subsistence system. Although these studies detailed the uses of various resources, little atten tion has been paid to the uses of marginal resources, which I believe are essential in discussing the San's deep and broad knowledge of nature. This paper will describe their extensive knowledge of insects. Through my research, I found that the San are usually in contact with insects in their daily lives and interact with them in various ways. -
