| Abstract Recently, the Neotropical brown stink bug, Euschistus heros (Pentatomidae: Hemiptera), has been detected in cotton in the Brazilian Cerrado. Several reliable surveys have been conducted on the spatial distribution of stink bugs in soybean; however, few studies have examined the behavior of this insect in cotton in Brazil. Thus, this study examined the spatial distribution of E. heros in cotton using aggregation indices based on the variance-to-mean ratio, Morisita index, exponent k, Poisson and negative binomial distributions. Inverse Distance Weighting interpolation maps were also used to represent insect density. The study was conducted in a 1.1 hectare experimental cotton field in which 64 equally-sized plots were sampled on a weekly basis. Our... |

| ABSTRACT The Brazilian Poplar Moth, Condylorrhiza vestigialis (Guenée), compromises the wood productivity of poplar trees (Populus sp.), mainly affecting the matchstick industry in southern Brazil. Considering the lack of information on rearing techniques for this insect, the objective of this study was to develop an artificial diet to rear C. vestigialis with biological characteristics similar to the wild insects. A properly diet will enable bio-ecological studies and biological control programs using the baculovirus Condylorrhiza vestigialis multiple nucleopolyhedrovirus (CvMNPV). To attain this objective, first, three artificial diets were tested. Only the diet based on corn, wheat germ and yeast as a protein source (Diet 3) was able to supply the... |

| The antifungal activity of aqueous extract of Cannabis sativa, Parthenium hysterophorus, Urtica dioeca, Polystichum squarrosum and Adiantum venustum was investigated against Alternaria solani, Alternaria zinniae, Curvularia lunata, Rhizoctonia solani and Fusarium oxysporum at different concentrations (5, 10, 15 and 20%). At 20%, maximum antifungal potential was observed with the extracts of C. sativa, which recorded excellent inhibitory activity against C. lunata (100%), A. zinniae (59.68%), followed by leaf extract of P. hysterophorus (50%) against A. solani. The application of botanical extracts for disease management could be less expensive, easily available, non-polluting and eco-friendly. |

| A tactic for control to corn leaf Rhopalosiphum maidis (Fitch, 1856) would be the use of resistant materials, but, for not being a key pest of the crop, there are not yet corn genotypes availables with those characteristics. So, it was aimed in this work to evaluate the effect of silicon on the aphid's development on corn plants. Preference tests with leaves detached from the plants and on corn plants were accomplished. Its was found that the treatments where silicon was applied to the soil plus a foliar sprayed fertilization or through two foliar applications were the ones which contained a lower number of aphids, increasing the resistance of leaves and making the feeding of those insects difficult. In general, the results showed that silicon affected the... |

| ABSTRACT: Genetic use restriction technologies (GURTs) were developed to preserve the intellectual property of genetically modified crops (GM) and ensure the return of investments made by industry to obtain technology delivered through seeds. The aims of this review are to discuss the GURTs and analyze their possible applications in integrated management of agricultural pests. There are two classes of GURTs: T-GURTs (trait-based GURTs), wherein the generated seed are viable, but the next generation does not express the trait of agronomic interest, and V-GURT (variety-based GURTs), in which plants produce non viable seeds. However, beyond the seed protection purpose, the GURTs could have also other application to solve agronomic problems. One of the most... |

| ABSTRACT: Pesticides are considered the first line of defense for the control of pests and diseases. At least in the short and medium term, the use of pesticides will remain an important strategy for pest management, allowing growers to produce crops of sufficient quality at low costs. A broad approach known as Integrated Pest Management (IPM) combines several different pest-control strategies, among which the combination of chemical and biological control stands out. It requires pesticides that achieve optimal control of target pests with minimal impact on the activity of biological control agents. Because of the dynamics of pest infestations, IPM routines are continuously adjusted by growers, requiring comprehensive information about pesticide effects on... |

| An alert system for tomato late blight was validated in an Integrated Production System (IP) in the 2006-2007 and 2007-2008 season in Caçador, Santa Catarina State, Brazil. The late blight is a destructive disease and demands 25 or more fungicide sprayings per season in a Conventional Production (CP) System. For the CP area, the chemical control was according to the growers' production systems and consisted of weekly sprays soon after planting. For the IP area, the criterion for the first fungicide spray was according to Machardy (1972) and for subsequent ones according to Wallin (1962), when the disease severity values (DSV) reached eight points. There was a decrease on the fungicide application in the IP, not only in the number of fungicide sprays... |

| This study assessed the cost and effectiveness of an integrated pest management (IPM) program using hydramethylnon gel baits compared with conventional spraying for controlling the German cockroach, Blattella germanica (L.) (Blattodea: Blattellidae), in two residential buildings in Yasuj, Iran. The IPM approach was based on educational programs using pamphlets, posters and lectures, sanitation using vacuuming and application of hydramethylnon gel baits. Conventional approach used cypermethrin (10% EC) on baseboard and cracks-and-crevices. Sticky traps were used as tools for monitoring cockroach population densities. The IPM approach reduced (943%) the rate of insecticide application compared to the conventional spray. Cockroach populations in the IPM... |

| The goal of this research was to use the sequential probability ratio test to establish a sequential sampling plan for Aphis gossypii Glover and Frankliniella schultzei Trybom infesting cotton. Field work was conducted at the agricultural experimental station of the Universidade Federal da Grande Dourados during the 2003/2004 and 2004/2005 agricultural years. Aphid colonies and individual thrips in the sampling area were counted and their numbers were recorded. The spatial distribution pattern of A. gossypii and F. schultzei in the cotton culture was aggregated. Sequential sampling plans were developed for aphids and thrips with type I and type II errors set at 0.1, common Kc = 0.6081 (aphids) and = 0. 9449 (thrips), and safety and management levels of 20%... |

| The in vitro compatibility of the entomopathogenic fungus Beauveria bassiana (Bals.) Vuil. with 12 acaricide formulations was evaluated. The active ingredients Clorfenapyr, Fenpyroximate, Amitraz, Acrinathrin, Hexythiazox, Abamectin, Pyridine, Dimethoate, Pyridaphethion, Fenbutatin Oxide, Azocyclotin and Cyhexatin were tested in three different concentrations (mean concentration - MC, half MC and twice the MC). The formulations tested affected conidial germination, vegetative growth and sporulation of the fungus in different levels. The formulations more compatible with B. bassiana were Avermectin and the pyrethroids. The acaricides belonging to the organophosphate and organostanic chemical groups, however, drastically affected conidial germination as well... |

| Abstract: The objective of this work was to address the classical biological control of pests in Brazil, regarding procedures to import and export native biological material. A brief introduction will be given on the current legal issues on the use of biocontrol agents, as well as some considerations on the existing quarantine pests and actions already carried out in the country. The safety in the introduction of exotic organisms is important for Brazilian phytosanitary defense and for a higher adoption of classical biocontrol, making it available for integrated pest management (IPM). Legal and normative aspects establish the procedures that must to be adopted, not only to protect bioprospecting and native organisms, but also to minimize risks to the... |

| Abstract: The objective of this work was to evaluate the natural resistance of soybean cultivars to Chrysodeixis includens. For this, four commercial soybean cultivars recommended for the Southern region of Brazil were used: BR 36, NA 5909 RG, BMX Turbo RR, and Benso 1RR. In the laboratory, larvae were subjected to the antixenosis feeding assay, in which they were free or not to choose among old leaves, new leaves, and pods. Neonate larvae were subjected to two antibiosis tests: in the first one, they were fed with leaves from the middle third of the plants of the four cultivars; and, in the second one, with leaves or pods of the NA 5909 RG cultivar. Chrysodeixis includens larvae prefer leaves over pods and old leaves over new ones. The Benso 1RR cultivar... |

| Firm characteristics and managers' attitudes and opinions about pesticide safety were used to classify lawn care and landscape management firms into four categories and compare them using the logit procedure. Survey data obtained from 223 firms was used in the empirical investigation of the adoption of the IPM techniques. Results showed the need for continued transfer of new technology to independently owned firms, multidisciplinary assessment of IPM methods before their transfer to ascertain the economic viability of proposed methods, public investment in programs training workers in knowledge-based pesticide applications, possible assistance in obtaining capital, and investment in consumer education. |
