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. -
Remote Sensing and Geographical Information Analytical Techniques for Modelling Ommatissus Lybicus (Hemiptera: Tropiduchidae) Habitat and Population Densities
Remote Sensing and Geographical Information Analytical Techniques for Modelling Ommatissus lybicus (Hemiptera: Tropiduchidae) Habitat and Population Densities Khalifa M Al-Kindi 1 , Paul Kwan Corresp., 1 , Nigel Andrew 2 , Mitchell Welch 1 1 School of Science and Technology, University of New England, Armidale, NSW, Australia 2 Centre for Behavioural and Physiological Ecology, University of New England, Armidale, NSW, Australia Corresponding Author: Paul Kwan Email address: [email protected] In order to understand the distribution and prevalence of Ommatissus lybicus (Homoptera: Tropiduchidae) as well as analyse their current biographical patterns and predict their future spread, comprehensive and highly sophisticated information on the environmental, climatic, and agricultural practices are essential. The analytical techniques available in modern spatial analysis packages, such as Remote Sensing and Geographical Information Systems, can help detect and model spatial links and correlations between the presence, absence and density of O. lybicus in response to climatic, environmental and human factors. The main objective of this paper is to review remote sensing and geographical information analytical techniques that can be applied in mapping and modelling the habitat and population density of O. lybicus in Oman. An exhaustive search of related literature revealed that there are few studies linking location-based infestation levels of pests like the O. lybicus with climatic, environmental and human practice related variables in the Middle East. Our review also highlights the accumulated knowledge and addresses the gaps in this area of research. Furthermore, it makes recommendations for future studies, and gives suggestions on monitoring and surveillance sites that are necessary in designing both local and regional level integrated pest management (IPM) policing of palm tree and other affected cultivated crops. -
5.Characterization of an Insecticidal Protein from Withania Somnifera.Pdf
Molecular Biotechnology https://doi.org/10.1007/s12033-018-0070-y ORIGINAL PAPER Characterization of an Insecticidal Protein from Withania somnifera Against Lepidopteran and Hemipteran Pest Blessan Santhosh George1 · S. Silambarasan2 · K. Senthil2 · John Prasanth Jacob2 · Modhumita Ghosh Dasgupta1 © Springer Science+Business Media, LLC, part of Springer Nature 2018 Abstract Lectins are carbohydrate-binding proteins with wide array of functions including plant defense against pathogens and insect pests. In the present study, a putative mannose-binding lectin (WsMBP1) of 1124 bp was isolated from leaves of Withania somnifera. The gene was expressed in E. coli, and the recombinant WsMBP1 with a predicted molecular weight of 31 kDa was tested for its insecticidal properties against Hyblaea puera (Lepidoptera: Hyblaeidae) and Probergrothius sanguinolens (Hemiptera: Pyrrhocoridae). Delay in growth and metamorphosis, decreased larval body mass and increased mortality was recorded in recombinant WsMBP1-fed larvae. Histological studies on the midgut of lectin-treated insects showed disrupted and difused secretory cells surrounding the gut lumen in larvae of H. puera and P. sanguinolens, implicating its role in disruption of the digestive process and nutrient assimilation in the studied insect pests. The present study indicates that WsMBP1 can act as a potential gene resource in future transformation programs for incorporating insect pest tolerance in susceptible plant genotypes.

Floral Volatiles from Vigna Unguiculata Are Olfactory and Gustatory Stimulants for Oviposition by the Bean Pod Borer Moth Maruca Vitrata
Article Floral Volatiles from Vigna unguiculata Are Olfactory and Gustatory Stimulants for Oviposition by the Bean Pod Borer Moth Maruca vitrata Bo Feng 1, Kai Qian 1 and Yong-Jun Du 1,2,* 1 Institute of Health and Environmental Ecology, Wenzhou Medical University, University Town, Wenzhou 325035, Zhejiang, China; [email protected] (B.F.); [email protected] (K.Q.) 2 Institute of Pesticide and Environmental Toxicology, Zhejiang University, 866 Yuhangtang Rd., Hangzhou 310058, Zhejiang, China * Correspondence: [email protected]; Tel.: +86-571-88982517 Academic Editor: Brian T. Forschler Received: 8 March 2017; Accepted: 6 June 2017; Published: 9 June 2017 Abstract: We investigated the role of floral odors from cowpea, Vigna unguiculata (L.), in mediating oviposition of the bean pod borer moth, Maruca vitrata, a serious pest of grain legumes that flies to host plants at the flowering stage and oviposits onto flowers and buds. The flower of the host plant V. unguiculata was a stimulus for egg-laying by M. vitrata in an oviposition bioassay. Commercial longifolene, β-caryophyllene, linalool, geraniol, and (Z)-3-hexenyl acetate were used as stimulus. Each one elicited dose-dependent electroantennogram responses in female M. vitrata, and all but longifolene stimulated oviposition, when presented singly. Beta-caryophyllene was the most active stimulant, similar to that of the flower of V. unguiculata, and eliciting a dose-dependent oviposition response. Either olfaction or gustation was sufficient to mediate an oviposition response to V. unguiculata floral volatiles: intact M. vitrata responded to β-caryophyllene whether or not they could contact the source of the volatiles, and females with amputated antennae responded if allowed to contact the source. -
Pluralibacter Gergoviae Als Spender- Oder Empfängerorganismus Gemäß § 5 Absatz 1 Gentsv
Az. 45241.0205 Juni 2020 Empfehlung der ZKBS zur Risikobewertung von Pluralibacter gergoviae als Spender- oder Empfängerorganismus gemäß § 5 Absatz 1 GenTSV Allgemeines Pluralibacter gergoviae (früher: Enterobacter gergoviae [1]) ist ein Gram-negatives, fakultativ anaerobes, peritrich begeißeltes, stäbchenförmiges Bakterium aus der Familie der Enterobacteriaceae, das zuerst 1980 beschrieben wurde [2]. Es ist weltweit verbreitet und wurde aus klinischen Proben (Blut, Urin, Sputum, Stuhl, Hautabstriche, Ohrendrainage, nicht näher beschriebene Wunden, Abszesse, Lunge, Niere) sowie aus dem Darm eines Roten Baumwollkapselwurms, Wasserproben und Kosmetikprodukten isoliert [2–7]. Das Überleben in Kosmetikprodukten wird dadurch ermöglicht, dass P. gergoviae eine hohe Toleranz gegen Konservierungsmittel wie Benzoesäure und Parabenen aufweist [8]. Aufgrund dieser Toleranz ist P. gergoviae in der Vergangenheit mehrfach als mikrobielle Verunreinigung in Kosmetikprodukten aufgetreten, die daraufhin zurückgerufen werden mussten [9]. Im klinischen Kontext tritt P. gergoviae vergleichsweise selten als Krankheitserreger auf. Das Bakterium löst vor allem bei Immunkompromittierten Infektionen aus, die tödlich verlaufen können. Es verursachte Harnwegsinfektionen oder Infektionen der Operationswunde bei Empfängern von Nierentransplantaten [10], mehrere Sepsisfälle auf einer Neugeborenenstation, von denen die Mehrzahl Frühgeborene betrafen [3], und führte zu einem Septischen Schock bei einem Leukämie-Patienten [11]. Bei Immunkompetenten wurden eine Sepsis -

The history/background in development of the SSGA method will be presented along with its advantages compared to other established methods. The usefulness of the SSGA method and how it can be implemented to gain circadian information on semiochemicals and pheromones will be demonstrated with examples of different pest insects such as moths, fruit flies, and mealybugs. I will also show how these volatiles can be further tested for their biological activity in order to optimize effective attractants.

Fighting this disease requires a reliable and inexpensive method for protecting orchards against pear psyllids, which are the major responsible of its transmission. The need for alternatives to insecticides has stimulated studies on the use of plant essential oils and plant extracts against pest insects. -

Front page: A Callosobruchus maculatus male (right) copulating with a female (left). Photo credit: Ivain Martinossi-Allibert. 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. -

Found in a single locality (Parszowice) in Lower Silesia, this species was recorded in a garden on Bryonia alba. Notes on the identification, biology and remarks on the general distribution and origin of the northern populations of this species are given. Colour photographs of the habitus and live specimens are also provided. Key words: Goniglossum wiedemanni, Carpomyini, species new for Poland, Lower Silesia, general distribution, Bryonia alba. INTRODUCTION Species from the family Tephritidae, the larvae of which develop in fruit, belong to the subfamilies Dacinae and Trypetinae. They occur most numerously in regions with a tropical or subtropical climate, where they pose a serious economic problem: in some areas they give rise to crop losses worth many millions of dollars. In central Europe, there are only a few species whose larvae feed on fruit; they belong exclusively to the tribes Carpomyini and Trypetini from the subfamily Trypetinae. -

The 3rd European Workshop on Sea Buckthorn (EuroWorkS2014) was held in Naantali, Finland on 14th to 16th of October 2014 under the theme “Producing Sea Buckthorn of High Quality”. Conference concentrated on three topics that were recognized to be current under the theme: sea buckthorn fly, cultivation technology and standardization of sea buckthorn. A special attention was paid to sea buckthorn fly because of its rapid and destructive invasion to Europe. Protective measurements need to be studied fast to get this new pest under control. Also long-term strategies are needed in order to continue efficient berry production, also without pesti- cides. Dr. Ljubov Shamanskaja has a long research experience with sea buckthorn fly in Barnaul, Rus- sia, where the fly has been a problem over 20 years. -
(Diptera: Tephritidae) Control in Mango
OPTIMIZATION OF AN INTEGRATED PEST MANAGEMENT PROGRAM FOR FRUIT FLIES (DIPTERA: TEPHRITIDAE) CONTROL IN MANGO: A CASE OF MANICA PROVINCE, MOZAMBIQUE LAURA DA GRAҪA JOSÉ CANHANGA A THESIS SUBMITTED IN FULFILMENT OF THE REQUIREMENTS FOR THE DEGREE OF DOCTOR OF PHILOSOPHY OF SOKOINE UNIVERSITY OF AGRICULTURE. MOROGORO, TANZANIA. 2018 ii EXTENDED ABSTRACT This study was undertaken to reduce the losses caused by Bactrocera dorsalis (Hendel) in Manica province, Mozambique, through an optimized integrated pest management (IPM) package. It involved interviews with farmers to collect baseline information on awareness of fruit producers regarding fruit fly pests and their management so that an IPM package can be developed based on the farmers’ needs. Additionally, systematic trapping data of B. dorsalis seasonality and damage were collected and economic injury level (EIL) for B. dorsalis was estimated. Based on EIL, the IPM for B. dorsalis control developed in Tanzania by the Sokoine University of Agriculture (SUA IPM) was optimized. The SUA IPM included calendar GF 120 NF bait sprays and orchard sanitation while for the optimized IPM the GF 120 NF was only sprayed in the subplots inside the orchard when the threshold of 30 flies/trap/week was reached. The effectiveness of SUA IPM and its optimized version were also tested. Results showed that fruit flies were the main pest problem in mango and citrus orchards. More than 70% the respondents indicated low fruit quality and increasing volumes of uncommercial zed fruits as consequences of fruit flies infestation. The monetary value of losses reached a value of USD 135,784.8 during 2014/15 mango season. -
