Abstract G. molesta is a serious pest of economic importance of commercial stone and pome fruits around the world. G. molesta damages peaches, nectarines, plums, cherries, apricots, apples, pears, quinces and nashi (Asian pears) and can also attack and cause economic damage on other commercial fruits. In severe attacks, young trees can suffer distortion of growing shoots and stems, which makes pruning, training and shaping the tree canopy difficult, particularly for close-planting industrial systems such as Tatura trellis. One larva can damage many shoots by tunnelling deep into young shoot tips. Larvae move to feed on the green fruits usually after shoots mature and harden. One larva can damage many fruits, particularly when fruits are located close to each other.

Oriental fruit moth, Grapholita molesta (Busck) (Lepidoptera: Tortricidae), is an important pest of stone and pome fruits. Growers usually depend on chemical insecticides to control this pest, but demand for more environmentally-friendly means of controlling pests is increasing. At least 77 plant extracts have been reported to be effective against other lepidopterans, but their acute toxicity against G. molesta has rarely been studied. Among these 77 materials, we assessed the residual toxicity of 32 extracts against first instar larvae (

Invasive species, those that are nonnative and cause economic damage, are one of the main threats to ecosystems around the world. Ambrosia beetles are some of the most common invasive insects. Currently, severe economic impacts have been increasingly reported for all the invasive shot hole borers in South Africa, California, Israel, and throughout Asia. This 7-page fact sheet written by Demian F. Gomez, Jiri Hulcr, and Daniel Carrillo and published by the School of Forest Resources and Conservation describes shot hole borers and their biology and hosts and lists some strategies for prevention and control of these pests. http://edis.ifas.ufl.edu/fr422

We review the continuing and extensive spread of Papilio demoleus in south-eastern Turkey and in regions of Turkey and Syria adjacent to the north-eastern Mediterranean. Since the authors documented the arrival of this attractive but potentially destructive papilionid species at coastal areas of Syria in 2019, regular monitoring has confirmed successful overwintering there, as well as in Turkey. As previously indicated, P. demoleus is widely recognized as an invasive pest species in Citrus-growing areas of the world and hence its arrival is of potential economic importance to a region in which citrus is widely grown.

With the first direct election to the European Parliament in the fall of 1979, there has been a renewed interest in the study of the European Community. While very few American universities offer courses on the European Community, more college and universities are including some coverage of the Community through course offerings on European politics or the study of international organizations.There are several reasons why the European Community is today receiving more attention by scholars and researchers. With the addition of three states in 1973, the nine member organization has become a significant economic force in the world. And because of the Community's economic importance, its decisions also have social and political implications.

Complex and contradictory processes of modern social transformations and the need to overcome the crisis in the economy require the appropriate influence of the state and a clear system of socio-economic management through the formation and implementation of effective state economic policy. The main elements of economic policy are financial and credit, budgetary, scientific and technical, structural, social, investment, agricultural, regional, foreign economic policy. The implementation of state economic policy is considered in terms of the relationship between social problems and the state. Therefore, the purpose of the article is to study the essence, tools and methods of state economic policy in modern conditions. It is also necessary to identify the main risks and features of further development of state economic policy of individual states in a global imbalance and crisis. The theoretical part is devoted to the study of the essence of state economic policy, theoretical and practical aspects of its organization in the state, as well as tools that can be used by the state. The resulting part is devoted to the consideration of the situation, in which the world economy has found itself in 2020 in the conditions of the economic COVID-19 crisis. General forecasts have not provided to individual states because it has been impossible to predict the end of the pandemic and the return of the world to normal life. However, it is clear that the world economy has undergone irreversible processes that will synergistically affect different states in different ways. The crisis has hit a significant number of industries, including tourism, logistics, hotel business, the crisis has been felt in world markets: oil prices have collapsed, as well as the stock markets. Undoubtedly, there are areas with a rapid growth, especially the pharmaceutical industry and retail, online delivery services, IT entertainment and communications industry, information marketing business and education and training services. It is likely that the indicators of economic development in the states by the end of the year will be better than the results of the first half of the year. The basic forecast of economic world development assumes a sharp growth of the economy after a short recession after quarantine. The financial capabilities of the EU states vary considerably, but each state must pursue counter-cyclical policies aimed at stabilizing its own economy. The answer to the question of what kind of crisis response policy they can afford depends on the fiscal policy of the states before the crisis. In economically developed states, where emergency measures have been introduced, governments and central banks issue trillions of dollars in government spending, social support of citizens, and interest-free business loans to limit the economic damage of quarantine. At the same time, in Latin America and Southeast Asia, total quarantine is impossible in multi-million cities. Such states have a triple effect of suffering from the virus, the environment and poverty. States dependent on the export of natural resources and raw materials, when faced with the crisis, are forced to sell them for nothing, so they will suffer great losses. More than 150 states have set up anti-crisis headquarters and are taking anti-crisis measures. The authors have also tried to predict how largescale the global economic crisis will be for Ukraine, what consequences await it, and what measures need to be taken to overcome it.

Corbicula fluminea (Müller, 1774) is an Asian freshwater clam that is widely distributed throughout the world through multiple introductions. Its invasion can cause environmental and economic damage. In Brazil, C. fluminea is recorded in all major hydrographic basins. Here, we report the first record of C. fluminea in the Chapada dos Veadeiros region of Goiás, Brazil. This new record extends the known distribution of this species to a conserved area in the Cerrado biome, towards areas of interest for conservation and integral protection units of the biodiversity.
