The fall armyworm, Spodoptera frugiperda (J.E. Smith, 1797) (Lepidoptera: Noctuidae), is the most important noctuid pest in Americas and has recently become an invasive Africa. A detailed record of S. frugiperda's host plants essential to better understand biology ecology this pest, conduct future studies, develop Integrated Pest Management programmes. In study, we collected systematically arranged fragmented bibliographic information on feeding records. Furthermore, registered new records...

As mariposas foram obtidas lagartas coletadas nas culturas algodão, milho soja, com uso armadilhas luminosas. coletas realizadas na Bahia, Distrito Federal, Mato Grosso Paraná. A identificação baseada genitália masculina análises das sequências dos genes mitocondriais do citocromo B região cox1-tRNALeu-cox2. comparada as...
ABSTRACT: Pesticides are considered the first line of defense for control pests and diseases. At least in short medium term, use pesticides will remain an important strategy pest management, allowing growers to produce crops sufficient quality at low costs. A broad approach known as Integrated Pest Management (IPM) combines several different pest-control strategies, among which combination chemical biological stands out. It requires that achieve optimal target with minimal impact on activity...
Abstract Pest management of stink bugs (Hemiptera: Pentatomidae) in soybean [ Glycine max (L.) Merr.], corn ( Zea mays L.) and cotton Gossypium spp.) agroecosystems has become a major concern several countries the Americas. In this review, we report an overview on geographical distribution, injury, damage methods used to control (plant resistance mechanisms, biological control) most important Americas, with emphasis Brazil, implications trend towards decreased susceptibility bug populations...
The objective of this work was to evaluate the soybean neotropical brown stink bug (Euschistus heros) resistance methamidophos through laboratory bioassays. Bioassays were carried out using populations adults and nymphs Euschistus heros in last instar collected crops Paraná State. Highest frequencies genotypes resistant observed Alvorada do Sul, Toledo Nova Santa Rosa, PR. Populations from Bela Vista Paraíso, Araruna, Campo Mourão, Mariluz, Cascavel, São João Ivaí, Mamboré more susceptible...
This work has the objective to catalogue information of Chrysodeixis includens (Walker, [1858]) (Lepidoptera: Noctuidae: Plusiinae) host plants. The list plants comprehends new reports in Brazil and from literature review around world. It is listed 174 which are 39 botanic families. higher number C. Asteraceae (29), Solanaceae (21), Fabaceae (18) Lamiaceae (12).
This study presents registers of Helicoverpa armigera (Hübner) occurrence to assess its spatial and temporal distribution in Brazil. We used data from collections, especially the Southern Region, systematic collections Rio Grande do Sul, occasional caterpillars adults different regions Brazil, as well literature registers. conclude that introduction H. Brazil probably occurred before October 2008. also register August 2012 was already present extreme southern part (Rio Sul) northern (Amapá)
This study aimed to detail the temporal and morphological parameters of immature stages southern armyworm Spodoptera eridania (Stoll, 1782) with larvae feed on artificial diet, under controlled conditions (25 ± 1°C, 70 10% relative humidity 14-h photophase) gather information about their larval host plants. The viability egg, larval, pupal, prepupal was 97.82, 93.62, 96.42, 97.03%, respectively. average duration pre–pupal 4.00, 16.18, 1.58, 9.17 d, During stage, 43.44% females passed through...
The fall armyworm, Spodoptera frugiperda (J. E. Smith, 1797), is the most important noctuid pest in Americas and has recently become an invasive Africa India. Having a detailed standardized record of biology larval development S. will be critical to further studies on integrated management, toxicology, applied ecology. This study reports temporal morphological parameters immature stages for larvae fed artificial diet under controlled conditions (25±1 °C, 70±10%...
Susceptibility of Alphitobius diaperinus (Panzer) (Coleoptera, Tenebrionidae) to cypermethrin, dichlorvos and triflumuron in southern Brazil. The lesser mealworm, (Panzer), is an important insect pest poultry houses the mealworm collected from eight Paraná state, Brazil, was evaluated for triflumuron. Adult A. were tested bioassays with cypermethrin dichlorvos. Larvae fed rabbit feed wetted a triflumuron-water solution. Concentration-mortality regressions estimated using Probit analysis...
The bollworm Helicoverpa armigera is a polyphagous pest first identified in the South American continent Brazil during 2012/13 crop season, worrying farmers across country that frequently overused insecticides an attempt to control its outbreaks. However, it essential emphasize importance of adoption Integrated Pest Management (IPM) philosophy, since improperly applied will exacerbate problems by eliminating biological agents and increase production cost unnecessarily. Therefore, our work...
Abstract Widespread adoption of MON 87701 × 89788 soybean, expressing Cry1Ac Bt protein and glyphosate tolerance, has been observed in Brazil. A proactive program was implemented to phenotypically genotypically monitor resistance Chrysodeixis includens (Walker). Recent cases unexpected injury soybean were investigated a large-scale sampling larvae on commercial fields performed assess the efficacy this technology distribution lepidopteran pests No significant shift C. susceptibility eight...
The Neotropical brown stink bug, Euschistus heros (F.), is usually controlled by organophosphate (OP) and cyclodiene (endosulfan) insecticides. Some unsuccessful control cases lead us to search for resistance these insecticides in E. heros, the most common bug soybean growing regions of Paraná State, São Paulo State Central Region Brazil. Bioassays were performed with endosulfan, monocrotophos metamidophos against adults. susceptible population was found Londrina. Populations from Pedrinhas...

Limited information exists on the insecticide susceptibility of redbanded stink bug, Piezodorus guildinii (Westwood) (Heteroptera: Pentatomidae), despite its impact soybean, Glycine max (L.) Merr., production in Brazil and United States. Therefore, this study set out to 1) determine baseline levels currently recommended pesticides using topical vial bioassays, 2) esterase activity populations States Brazil, 3) compare control among products field trials.
