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.

Learn By Doing

California Polytechnic State University's (Cal Poly) learn-by-doing philosophy permeates all areas of the environmental horticultural science curriculum by combining an emphasis on the science of horticulture in lecture sessions and the opportunity to engage in activities similar to those used by industry in the lab activities integral in all courses. The course, Disease and Pest Control Systems in Ornamental Plants (EHS 427), has taken this philosophy a step further by using problem-based learning and allowing students to function as pest control advisors and qualified applicators in the class. This approach has resulted in greatly increased student understanding of pest control, improved student morale, and increased interest in integrated pest management careers and research projects.

Diabrotica Speciosa

Abstract The rootworm Diabrotica speciosa (Germar) is native to South America and causes severe economic losses to several crops due to root feeding and disease spread. In maize (Zea mays L.), losses in production come from larval rootworm attack on plant roots resulting in plant health problems, including stalk lodging. More options for controlling this pest are needed to create well balanced, integrated pest management programs for farmers in this region. Natural sources of tolerance in maize genotypes are important for maize breeding programs, and this study investigated the expression of tolerance in several Brazilian maize landraces to D. speciosa. Plant vigor and compounds associated with plant health, including chlorophylls, carotenoids, glycine betaine, and proline were assessed for each landrace. Five landraces and one maize cultivar were selected based on their levels of antibiosis-resistance to D. speciosa that were determined in a prior screening. The percent reduction in plant growth was used as the measure of tolerance. The landrace Azteca was classified as tolerant to D. speciosa larval feeding, displaying less reduction in plant matter despite having lower plant vigor. This landrace also had higher amounts of chlorophyl and carotenoid pigments, suggesting a positive correlation between tolerance to D. speciosa and higher contents of these photosynthetic pigments. The compatible osmolytes glycine betaine and proline do not seem to be associated with tolerance in maize landraces to D. speciosa larvae. Landrace Azteca seems promising for plant breeding, and repeated field studies are needed to confirm its suitability in maize integrated pest management.

Family Based

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.

As part of a continual search for potential pathogens of insects for use in biological control or on an integrated pest management program, two bacilliform virus-like particles (VLP) of similar morphology have been found in the Mexican bean beetle Epilachna varivestis Mulsant and the house cricket, Acheta domesticus (L. ).Tissues of diseased larvae and adults of E. varivestis and all developmental stages of A. domesticus were fixed according to procedures previously described. While the bean beetles displayed no external symptoms, the diseased crickets displayed a twitching and shaking of the metathoracic legs and a lowered rate of activity.Examinations of larvae and adult Mexican bean beetles collected in the field in 1976 and 1977 in Maryland and field collected specimens brought into the lab in the fall and reared through several generations revealed that specimens from each collection contained vesicles in the cytoplasm of the midgut filled with hundreds of these VLP's which were enveloped and measured approximately 16-25 nm x 55-110 nm, the shorter VLP's generally having the greater width (Fig. 1).
