The evolution of these function- ally important traits can be reconstructed within the Lepidoptera. The proboscis movements are explained by a hydraulic mechanism for un- coiling, whereas recoiling is governed by the intrinsic proboscis mus- culature and the cuticular elasticity. Fluid uptake is accomplished by the action of the cranial sucking pump, which enables uptake of a wide range of fluid quantities from different food sources. Nectar-feeding species exhibit stereotypical proboscis movements during flower han- dling. Behavioral modifications and derived proboscis morphology are often associated with specialized feeding preferences or an obligatory switch to alternative food sources. -
Influence of Protein and Fat Contained in the Sunflower on the Number and Population Crowded Sunflower Moth (Homoesoma Nebulella Hb.)
EUROPEAN ACADEMIC RESEARCH Vol. II, Issue 11/ February 2015 Impact Factor: 3.1 (UIF) ISSN 2286-4822 DRJI Value: 5.9 (B+) www.euacademic.org Influence of protein and fat contained in the sunflower on the number and population crowded Sunflower Moth (Homoesoma nebulella Hb.) NAZAKAT N. ISMAYILZADE Department of Entomology Azerbaijan State Agrarian University Republic of Azerbaijan Abstract The measures carried out without taking into account the factor of food is the reason for the decrease in economic efficiency of the plant and leads to environmental pollution. For the reason that variety Maslyanka the amount of protein and fat significantly more than in other varieties of sunflower number Homoesoma nebulella it is significantly less than what causes 1,2% damage of seeds of sunflower. Keywords: Azerbaijan, protein, sunflower moth, Homoeosoma nebulella, sunflower The stability of any insect pest significantly depends on the quantity and quality of food intake. The amount of protein, fats and other substances in the diet helps to increase the reproductive capacity of the insect and resistance to adverse environmental conditions. From this point of view, our aim is to study the survival depending on the factor of food dangerous pest of sunflower Homoesoma nebulella. Homoesoma nebulella eats sunflower seeds, which is accompanied by loss of crop. In the years of mass reproduction yield losses are particularly large. Carrying out control measures without taking into account the factor of food accompanied by a reduction in economic efficiency and environmental pollution. With the aim of increasing the economic effectiveness of measures to combat the pest takes into account the effects of food on mortality and survival of the pest. -

South-Central England Regional Action Plan
Butterfly Conservation South-Central England Regional Action Plan This action plan was produced in response to the Action for Butterflies project funded by WWF, EN, SNH and CCW by Dr Andy Barker, Mike Fuller & Bill Shreeves August 2000 Registered Office of Butterfly Conservation: Manor Yard, East Lulworth, Wareham, Dorset, BH20 5QP. Registered in England No. 2206468 Registered Charity No. 254937. Executive Summary This document sets out the 'Action Plan' for butterflies, moths and their habitats in South- Central England (Dorset, Hampshire, Isle of Wight & Wiltshire), for the period 2000- 2010. It has been produced by the three Branches of Butterfly Conservation within the region, in consultation with various other governmental and non-governmental organisations. Some of the aims and objectives will undoubtedly be achieved during this period, but some of the more fundamental challenges may well take much longer, and will probably continue for several decades. The main conservation priorities identified for the region are as follows: a) Species Protection ! To arrest the decline of all butterfly and moth species in South-Central region, with special emphasis on the 15 high priority and 6 medium priority butterfly species and the 37 high priority and 96 medium priority macro-moths. ! To seek opportunities to extend breeding areas, and connectivity of breeding areas, of high and medium priority butterflies and moths. b) Surveys, Monitoring & Research ! To undertake ecological research on those species for which existing knowledge is inadequate. Aim to publish findings of research. ! To continue the high level of butterfly transect monitoring, and to develop a programme of survey work and monitoring for the high and medium priority moths. -

Review of Evidence Concerning Ragwort Impacts, Ecology and Control Options
Review of evidence concerning ragwort impacts, ecology and control options Report to Defra OCTOBER 2013 Authors: Ruth Laybourn, Debbie Kessell, Naomi Jones, Simon Conyers, Caroline Hallam, Nigel Boatman Food and Environment Research Agency Sand Hutton, York, YO41 1LZ 1 2 EXECUTIVE SUMMARY Introduction Ragwort is a widespread native plant in the UK, which occurs in a range of habitats including those used for grazing livestock and hay or silage production, and is of concern because it contains pyrrolizidine alkaloids (PAs) which are toxic to livestock. Problems have occurred particularly with poisoning of horses. Ragwort is a specified weed in the Weeds Act 1959, under which land owners can be required to take all reasonable steps to prevent spread on their land and onto adjoining land. Defra have issued a Code of Practice on How to Prevent the Spread of Ragwort, which was published in 2004 (revised 2007) (Defra, 2007). In order to ensure that guidance continues to be based on the latest and best evidence, the work reported here was commissioned by Defra with the following objectives: o Review and update the evidence base on the impacts of ragwort on livestock, methods of control and the cost, benefits and impacts of control; o Investigate experience of ragwort problems, policy and control in other countries o Make suggestions relating to the Code of Practice and further research needs. Biology and ecology Studies of Ragwort ecology and distribution have shown that: Ragwort is found in a wide range of habitats but requires bare ground or disturbance to establish. Ragwort plants form a rosette in their first year and typically flower, set seed and die in the second year, though in some situations they can be longer lived. -

Current Status and Future Perspectives on Sunflower Insect Pests
Current status and future perspectives on sunflower insect pests Jarrad R. Prasifka, Brent S. Hulke U.S. Department of Agriculture, Agricultural Research Service, Northern Crop Science Laboratory, 1307 18th Street North, Fargo, ND 58102, USA, E-mail: [email protected], [email protected] ABSTRACT While occasional insect pests of cultivated sunflowers may be managed by conventional or reduced- risk insecticides, the cumulative costs and risks of relying on insecticides to suppress perennial or severe pests (common in North America) call for exploration of broader pest management strategies. Recent research with the sunflower moth (Homoeosoma electellum [Pyralidae]) and banded sunflower moth (Cochylis hospes [Tortricidae]) in North America has focused on finding host plant resistance in Helianthus spp. and understanding the mechanisms of resistance. Two flies, the sunflower midge (Contarinia schulzi [Cecidomyiidae]) in North America, and sunflower head fly (or mosquita del capítulo, Melanagromyza minimoides [Agromyzidae]) in South America provide examples of severe pests which can be particularly problematic over limited areas of their geographic ranges; management of both fly species could benefit from additional research. Work with insect pests of sunflower in North America shows the increasing potential of using integrated pest management (IPM) tactics, particularly forms of host plant resistance (antibiosis, antixenosis, tolerance) often derived from interspecific hybrids or accessions of Helianthus annuus. Economic and other practical considerations may preclude significant use of transgenic insect- resistance (e.g., expressing toxins from Bacillus thuringiensis [Bt]), but because single traits native to Helianthus spp. do not appear capable of providing resistance equivalent to insecticides, two or more independent types of resistance should be combined whenever possible.
