Understanding the genetic basis of insect resistance to insecticides can help implement insecticide management (IRM) strategies. In this study, we selected a strain Spodoptera frugiperda (J. E. Smith) (Lepidoptera: Noctuidae) resistant chlorantraniliprole using F2 screen method, characterized inheritance and evaluated patterns cross-resistance other diamide insecticides.The chlorantraniliprole-resistant (Chlorant-R) was from field-collected population with an estimated allele frequency...
Abstract BACKGROUND Fall armyworm (FAW), Spodoptera frugiperda (J.E. Smith), a major lepidopteran pest in Latin and North America, has very recently invaded the continents of Africa Asia. FAW evolved resistance to different insecticides transgenic corn expressing Bacillus thuringiensis (Bt) toxins. Here, we investigated extent mechanisms diamide Brazilian field‐collected strain selected using chlorantraniliprole. RESULTS Continuous laboratory selection with chlorantraniliprole resulted...
The use of spinosyn insecticides is one the major control strategies fall armyworm, Spodoptera frugiperda (J. E. Smith) in Brazil. In this study, we selected a spinetoram-resistant strain from field-population S. to characterize inheritance resistance and cross-resistance relationship between insecticides.The values LC50 (95% CI) obtained concentration-response bioassays were 0.63 (0.55-0.73) μg spinetoram mL-1 for susceptible (SUS), 1170.96 (1041.61-1323.89) resistant (SPT-R). These...
Spodoptera frugiperda (J.E. Smith) is one of the key cross-crop pests in Brazilian agroecosystems. Field-evolved resistance S. to some conventional insecticides and Bt proteins has already been reported. Thus, use with new mode action such as sodium channel blockers (indoxacarb metaflumizone) could be an important tool insecticide management (IRM) programs. To implement a proactive IRM, we conducted baseline response monitoring indoxacarb metaflumizone 87 field populations collected from...
Anastrepha grandis (Macquart) (Diptera: Tephritidae) is one of the main pests cucurbits in Brazil. Losses occur due to damage caused fruits and embargo on exports, as A. considered a quarantine pest countries that import Brazilian cucurbits. This study aimed evaluate development hosts Cucurbitaceae family. The used were stem squash ( Cucurbita pepo L.), moschata Duchesne), chayote [ Sechium edule (Jacq.) Swartz], mini watermelon Citrullus lanatus (Thunb.) Matsum & Nakai], Spanish melon...
The effects of sclerocorneal limbal stem cell autograft transplantation in dogs with corneal wounds were studied. Eighteen divided two groups (GI and GII). animals GI (n=12) underwent 30 days after the destruction cells. GII (n=6) only cells (control group). Light microscopy examination right eye was performed on 3, 7, 14, 30, 60, 120 (GI), 33, 37, 44, 90, 150 (GII). Results showed a complete loss transparency. Limbal prevented conjunctivalization grafted area. Corneal vascularization 360º...
Microtheca spp. (Coleoptera: Chrysomelidae) are insect pests primarily related to Brassicaceae crops. In the State of Rio Grande do Sul (RS), southern Brazil, they found on forage turnip, Raphanus sativus L. var. oleiferus Metzg., which is commonly grown during fall/winter seasons. This work reports predation larvae by Toxomerus duplicatus Wiedemann, 1830 (Diptera: Syrphidae) larvae, turnip crop, in Santa Maria, RS. register provides new information about natural enemies might be a option...
Abstract Stiretrus decastigmus (Herrich-Schaeffer) (Hemiptera: Pentatomidae) is an important predator of the insect pest Microtheca ochroloma Stal (Coleoptera: Chrysomelidae). The present study investigated pre-imaginal development S. at different temperatures. temperatures were: 20, 25, and 30 °C, with a relative humidity 70 ± 10% photofase 12 h, nymphs were fed larvae M. ochroloma. We evaluated duration viability egg nymphal stages, each instar, predation potential. incubation time...
The objective of this study was to evaluate the clinical and histological effects occluding nasolacrimal ducts points rabbits. For study, 20 adult New Zealand rabbits, both males females, weighing 3.2±0.4kg were allocated into two groups for n-butyl-cyanoacrylate occlusion (GB, n=10) or 2-octyl-cyanoacrylate (GO, n=10). contralateral eyes served as controls. persistence tears evaluated daily using Schirmer I test. Discomfort, eye discharge, epiphora, conjunctival hyperemia assessed prior...
First record of larvae Allograpta exotica Wiedemann (Diptera, Syrphidae) preying on Aphis gossypii Glover (Hemiptera, Aphididae) in watermelon Brazil. Brazil is one the largest world producers (Citrullus lanatus Thumb. Mansf.) and Glover, 1877 among most important pest this crop. Larvae Wiedemann, 1830 were found A. crop, Santa Maria, Rio Grande do Sul State, what represents first report tritrophic association
Aphis craccivora Koch (Hemiptera: Aphididae) é um afídeo-praga que ocorre em diferentes cultivos e causa danos relacionados ao hábito da sucção de seiva. No Brasil, são raros os registros plantas daninhas hospedeiras dessa espécie, particularmente no Estado do Rio Grande Sul (RS). Plantas infestadas com afídeos foram encontradas área experimental localizada campus Universidade Federal Santa Maria (UFSM), RS, duas datas, 22/02/2010 25/03/2010. segundo registro (25/03/2010), cada planta...
O objetivo deste trabalho foi determinar o tamanho de amostra (número insetos) para a estimação da média duração dos períodos larval, pupal e larval + Microtheca ochroloma semilaevis (Coleoptera: Chrysomelidae). Foram coletados adultos dessas espécies em uma área experimental 0,25ha nabo forrageiro (Raphanus sativus L.) estabelecida criação laboratório (temperatura 25±2°C, umidade relativa 60±10% fotoperíodo 12 horas). Após, foram mensurados os pupal, dias, 119 81 insetos, respectivamente,...
Brazil is among the world's biggest maize producers and fall armyworm, Spodoptera frugiperda (Smith) (Lepidoptera: Noctuidae), main insect pest on this crop in country. Despite importance of its natural enemies, there still a lack information about parasitoids species that attack insect-pest, such as larval parasitoids. This research reports Euplectrus furnius Walker (Hymenoptera: Eulophidae) parasitizing S. fugiperda larvae Brazil.
The effects of metaraminol bitartrate on intraocular pressure (IOP) were studied in dogs anesthetized with halothane. Forty-five healthy, adult, mixed-breed dogs, both sexes, divided into three groups 15 each (GI, GII and GIII) maintained under general anesthesia halothane after tranquilization levomepromazine induction thiopental. Saline (0.9%) was administered intravenously (IV) to GI through continuous infusion, at a velocity 0.125 mL kg-1 min-1. GIII received 0.004% IV, dose 5 &mgr;g...
