1. Record of Conotelus luteicornis Erichson (Coleoptera: Nitidulidae) in passion fruit vine in Acre state, Brazil
ABSTRACT The first record of Conotelus luteicornis Erichson (Coleoptera: Nitidulidae) was made in a commercial passion fruit vine planting in the municipality of Senador Guiomard, Acre state, Brazil. The insects were found inside the flowers where larvae and adults feed, causing early abortion and, consequently, losses in production. Therefore, the first rec

2. CHLORDECONE ADSORPTION ON FUNCTIONALIZED ACTIVATED CARBONS: COMPUTATIONAL CHEMISTRY AS A TOOL FOR UNDERSTANDING THE ADSORPTION PROCESS
Chlordecone (CLD) has been used as a pesticide for a long time to control the proliferation of various insects in tropical countries like the French West Indies. CLD was included in 2009 in the list of persistent organic pollutants (POPs) by the Stockholm Convention, prohibiting its production and use worldwide. Thus, its removal from water and soils is a sa

3. Effectiveness of coffee leaf miner control associated with spray deposition in coffee leaves
ABSTRACT Coffee production faces challenges due to the susceptibility of the crop to insects. Owing to the coffee leaf miner Leucoptera coffeella, which is one of the main insect pests, the technology for the application of phytosanitary measures becomes the main challenge for coffee growers. This study aimed to evaluate the effectiveness of coffee leaf mine

4. Evaluation of the injuries caused by Pachycoris torridus (Scopoli, 1772) (Hemiptera: Scutelleridae) in Jatropha curcas (Linnaeus) (Euphorbiaceae)
ABSTRACT The Jatropha curcas species is a perennial plant and easy to manage, being cultivated in many countries because of its high content in oil and the lowest cost of production. This study had as objective to evaluate the injuries caused by the Pachycoris torridus in J. curcas seedlings. Thirty-four days after the planting, 30 J. curcas seedlings were c

5. Association of Mechanical and Chemical Methods for Cotton Stalk Destruction
RESUMO: A destruição de soqueiras do algodoeiro após a colheita é uma medida profilática que visa reduzir a população de insetos-praga e de inóculos de doenças que podem permanecer alojados nos restos culturais e plantas de algodoeiro remanescentes. O objetivo deste trabalho foi avaliar métodos integrados de manejo das soqueiras, conciliando contro

6. Silicon as resistance inducer in to control black aphid Aphis craccivora Koch, 1854 in Phaseolus lunatus lima beans
RESUMO São poucos os registros no Brasil de insetos associados à cultura da fava; entre eles, destaca-se o pulgão preto Aphis craccivora Koch, 1854. O objetivo deste estudo foi avaliar os efeitos da aplicação de silício na indução de resistência de plantas de feijão-fava Phaseolus lunatus a esse inseto. O experimento foi conduzido no Laboratório d

7. Persistence of insecticides used in peach orchards to larvae and adults of the predator Chrysoperla externa (Neuroptera: Chrysopidae)
RESUMO Este trabalho teve como objetivo avaliar a persistência (duração da atividade nociva) de cinco inseticidas utilizados no controle de pragas em pessegueiro, em larvas e adultos do predador Chrysoperla externa. Os inseticidas foram pulverizados em plantas de videira cv. Bordô utilizando-se a máxima dosagem recomendada para o pessegueiro. Semanalmen

8. Verification of atmospheric plasma irradiation as an alternative control method for Tribolium castaneum (Herbst)
Resumo Plasma de radiofrequência, plasma de RF, tem sido empregado em diversas aplicações industriais. Experimentos de laboratório foram conduzidos para determinar o potencial de plasma de RF no controle de Tribolium castaneum (Herbst). Foram examinados nesse estudo três variáveis de tratamento: (1) plasma de hélio ou argônio; (2) dois níveis de pot

9. Triatomine dispersion rates and their association with socioeconomic and environmental conditions in Northeastern Brazil, from 2009 to 2013
ABSTRACT Triatomines are vectors of Trypanosoma cruzi , the etiological agent of Chagas disease, which affects between 6 and 12 million people in Latin America, with an incidence rate of 12 thousand cases per year. In the Ceara State, the predominance of the caatinga biome, coupled with a large rural area with precarious human habitations, provides several s

10. TOXICITY OF ALKALOID FRACTIONS FROM Psychotria spp. (RUBIACEAE) AGAINST Atta sexdens FOREL, 1908 (HYMENOPTERA: FORMICIDAE)
ABSTRACT Leaf-cutting ants are the main pests in forest plantations. The most commonly used chemical control for the ants is toxic bait. However, the active ingredients in these baits have been restricted by forest certification organizations, justifying the search for new active compounds to control these insects. Thus, this work aimed to evaluate the formi

12. Bioassay Technique and Maintenance of Gyropsylla spegazziniana (Lizer, 1719) (Hemiptera: Psylloidea: Aphalaridae) in vitro Conditions
ABSTRACT Gyropsylla spegazziniana is one of the most important pest of yerba mate by sap-sucking that lead to leaves deformation and there are no insecticides registered for its control. The present study describes a new technique to be used in bioassays with the insect. Galls were collected from infested yerba mate plants. In the laboratory, the galls were
