In the state of Acre, Brazil, family-based agriculture is predominant and although it has less economic impact in relation to large-scale plantations, it is also subject to biological imbalances, such as the attack of pests, generating economic losses for producers. Phytosanitary knowledge in the state is still incipient and becomes an obstacle to production, often resulting in mistaken management decisions. In this context, this work aimed to present a history of research carried out in the field of Agricultural Entomology, especially in the areas of integrated management and biological control of pests of the most relevant crops grown in the Acre state. In this review, 55 scientific papers related to Agricultural Entomology were presented, 23 on new insect records and/or new insect associations with host plants, 16 on insect control using plant extracts from the Amazon region, 13 on integrated pest management and three on bioecology and population dynamics of pests in the state of Acre. Through this review, it is observed that research in the area  of Agricultural Entomology in the state of Acre is characterized by basic research (surveys, registration of new species, bioecological and dynamic population studies). However, there has been a notable advance in scientific studies aimed at integrated pest management in the state in the past ten years. Still, there is a need to concentrate efforts on research aimed at prospecting and using Amazonian biodiversity (fauna and flora), which subsidize applied programs for integrated pest management of the main crops grown in the Acre state.

Abstract As a result of the latest economic recession (2007 to 2009), the U.S. green industry suffered significant economic losses, leading to major industry structural changes. To be competitive and effectively manage risk, nursery and greenhouse operators need reliable and up-to-date information. However, the availability of such data from federal government sources has become limited. This report summarizes the state of the industry, focusing on trends in production-related characteristics from the 2009, 2014, and 2019 survey years. As firm size increased, the percent of annual sales attributed to large plant species (e.g., deciduous trees) increased, while herbaceous (e.g., perennials) and specialty (e.g., Christmas tree) plants made up a larger percentage of annual sales for small- and medium-sized firms. The majority of respondents (73.3%) indicated a proportion of their sales came from container-grown plants. The most frequently used integrated pest management (IPM) practice was removal of infested plants (81%), followed by cultivation/hand weeding. As firm size increased, participation in IPM strategies increased. Interestingly, statistical differences between small- and medium-sized firms were infrequent, indicating similar levels of use; however, most of the IPM strategies used were more frequently employed by large-sized firms when compared to small- or medium-sized firms. Index words: Container-grown, greenhouse, integrated pest management (IPM), nursery, ornamental plants.

Chemical Residues

Entomopathogenic nematodes (EPNs) are insect parasites that are used successfully as biological controlagents against key pest insects of grapevine. To achieve low chemical residues and the sustainableproduction of grapes, it is important that biological control agents such as entomopathogenic nematodesfor the control of grapevine insect pests be incorporated in an integrated pest management system forgrape production. However, the commercialisation and large-scale use of EPNs is limited by their shortshelf life in formulations and in storage, thus leading to poor quality and reduced efficacy against insectsin the field. In South Africa, interest in the use of EPNs within an integrated pest management system hasgrown over the past two decades, therefore developing a formulation technique with an acceptable storagesurvival period, while maintaining infectivity, is essential. Moreover, the successful control of insects usingEPNs is only achievable when the formulated product reaches the end user in good condition. This reviewis focused on the different types of formulations required for storage and ease of transport, together withthe application formulation for above-ground pests and the factors affecting them. The quality assessment,storage and handling of formulated EPNs are also discussed.

Over Time

In Integrated Pest Management (IPM), the costs of a control measure are compared to the potential for economic losses caused by a pest, with control measures being recommended only when expected costs of losses exceed costs of control. IPM models have been developed largely for insect pests, which multiply rapidly and for which timely population assessments are thus essential. Weed pests, on the other hand, multiply slowly. In the case of perennial crops, weeds may not reach populations sufficient to warrant control under conventional IPM criteria for many years. It is proposed that IPM concepts be adapted to weedy pests of perennial crops by creating models in which the long-term costs and consequences of both weeds and weed control measures are considered. These models would take into account expected increases in control costs and decreases in effectiveness of control measures over time and as a consequence consider some weeds to have effective thresholds at or near zero.

Rice Intensification

Since many years, the agro-technical programs such as "3 reduction 3 increase", "1 must 5 reduction" and System of Rice Intensification (SRI) have been carried out with definite results. Recently, IPM program (integrated pest management) – a more comprehensive measure (using all possible techniques and methods to keep the pest populations below a level causing economic injury) – has been firstly piloted on a large scale in the Mekong Delta. This paper presents the main results of piloting IPM program in 2,610 hectares during 2014-2017 in Hau Giang province. As results, farmers have better economic benefit in production; the quality of rice has been gradually improved and can overcome the technical barriers of advanced countries in rice trade such as US, EU and Japan. In addition, the environmental and ecological consequences can be avoided due to overuse of fertilizer and pesticide. Field ecosystems will be gradually restored. Từ nhiều năm nay những chương trình kỹ thuật nông nghiệp như "3 giảm 3 tăng", "1 phải 5 giảm" và hệ thống canh tác lúa cải tiến (SRI) đã được áp dụng và đã có những kết quả nhất định. Còn chương trình quản lý dịch hại tổng hợp IPM - một biện pháp tổng hợp và tích cực hơn (sử dụng tất cả các kỹ thuật và biện pháp thích hợp có thể được, nhằm duy trì mật độ của các loài gây hại dưới mức gây ra những thiệt hại kinh tế) –  được thực nghiệm đầu tiên trên diện rộng ở Đồng bằng sông Cửu Long. Bài báo này trình bày những kết quả chính trong thử nghiệm ở 2.610 ha lúa trong thời gian 2014-2017 ở ở tỉnh Hậu giang. Kết quả là quản lý dịch hại ở ngưỡng cho phép, người nông dân có lợi hơn về kinh tế trong sản xuất, chất lượng gạo từng bước được cải thiện và có khả năng vượt qua các hàng rào kỹ thuật trong thương mại lúa gạo của các nước tiên tiến như USA, châu Âu, Nhật Bản. Ngoài ra tránh được hệ quả về môi trường sinh thái do sử dụng quá mức phân bón hóa học và ô nhiễm do thuốc bảo vệ thực vật và hệ sinh thái đồng ruộng dần được phục hồi.

Management Tools

Bacillus-based biological control agents (BCAs) have great potential in integrated pest management (IPM) systems; however, relatively little work has been published on integration with other IPM management tools. Unfortunately, most research has focused on BCAs as alternatives to synthetic chemical fungicides or bactericides and not as part of an integrated management system. IPM has had many definitions and this review will use the national coalition for IPM definition: “A sustainable approach to managing pests by combining biological, cultural, physical and chemical tools in a way that minimizes economic, health and environmental risks.” This review will examine the integrated use of Bacillus-based BCAs with disease management tools, including resistant cultivars, fungicides or bactericides, or other BCAs. This integration is important because the consistency and degree of disease control by Bacillus-based BCAs is rarely equal to the control afforded by the best fungicides or bactericides. In theory, integration of several tools brings stability to disease management programs. Integration of BCAs with other disease management tools often provides broader crop adaptation and both more efficacious and consistent levels of disease control. This review will also discuss the use of Bacillus-based BCAs in fungicide resistance management. Work with Bacillus thuringiensis and insect pest management is the exception to the relative paucity of reports but will not be the focus of this review.

Environmentally Safe

Tremendous increases in pesticide use in cotton growing areas have severely affected the health of peoples and degraded environment [Poswal and Williamson (1998); Ahmad and Poswal (2000); Orphal 2001 and Khan (2000)]. Farmer Field School (FFS) based IPM implemented in the world to reduce dependence on pesticides and promote environmentally safe plant protection practices. An FFS-led Integrated Pest Management (IMP) model implemented in Pakistan during 1996—popularly known as “Vehari Model”, clearly demonstrated that IPM could be implemented on a large scale at the farm level. UNDP-FAO Policy Reform Project provided required policy level support to scale up the Farmer-led IPM in the country. Implementation of pesticide policy project in Pakistan highlighted that pesticide consumption increased from 665 metric tons in 1980 to 78,132 metric tons in 2003-4. The role of private sector in promoting the production and use of pesticides was found tremendously high. The private sector also took full advantage of government’s pesticide import liberalisation policies. One of the key components of dramatic increase in pesticide use in Pakistan is related to very soft import and registration at that time, which allowed the generic compounds registered elsewhere, to be imported without fieldtesting.

Successful Production

Coffee (Coffea sp.) Is a crop of great economic relevance, it stands out as one of the most important agricultural commodities for the country. As with any other high value-added crop, coffee crops suffer from the attack of many pests, and proper management of these pests is critical to successful production. Integrated Pest Management (IPM) is a pest management system that associates the environment and population dynamics of the pest, considers the use of all available plant protection methods and the integration of appropriate measures to maintain the population level of thepest below the level of damage in an economically, environmentally and ecologically viable way. The purpose of this literature review was to gather information on research involving the integrated management of pests in the coffee crop.
