The predatory bug Orius insidiosus is an important biological control agent of several insect pests, and one the most commonly used species in programs worldwide. This study assessed lethal sublethal effects insecticides on this through life table, classified according to definitions toxicity given by International Organization for Biological Integrated Control Noxious Animals Plants (IOBC). A bioassay was carried out using a completely randomized design with eight treatments 40 replicates....
Fall armyworm Spodoptera frugiperda (J.E.Smith, 1797) (Lepidoptera: Noctuidae) is an important pest of maize (Zea mays L.) crops in Brazil.The effects beta-cypermethrin, chlorfenapyr, chlorpyrifos, spinosad, etofenprox, triflumuron, alpha-cypermethrin/teflubenzuron, and lambda-cyhalothrin/thiamethoxam on Trichogramma pretiosum Riley, 1879 (Hymenoptera: Trichogrammatidae) immature stages were evaluated.Eggs Anagasta kuehniella (Zeller, 1879) Pyralidae), containing the parasitoid dipped water...
We studied the community of fruit flies in an agricultural habitat (guava orchards) and adjoining native vegetation, a caatinga-cerrado transition region state Minas Gerais, Brazil. Sampling was conducted with McPhail traps by collecting guavas other fruits vegetation. The 3 most common fruit-fly species orchards were Anastrepha zenildae Zucchi, A. sororcula fraterculus (Wiedemann), whereas forest fragments zenildae, picked Lima, montei Lima. recorded forests also collected guava orchards....
Corn (Zea mays L.) is cultivated in large areas and considered one of the world's major cereal crops.There are several arthropod pests that can reduce its production such as fall armyworm, Spodoptera frugiperda (J.E.Smith) (Lep.: Noctuidae), which to be main pest for corn.Fall armyworm primarily controlled by insecticides.The use biological control agents manage this growing with an emphasis on egg parasitoid Trichogramma pretiosum Riley (Hym.: Trichogrammatidae).Thus, aim research was...
The aim of this work was to evaluate the toxicity insecticides imidacloprid/ß-cyfluthrin (Connect 100/12.5 SC), chlorfenapyr (Pirate 240 chlorpyrifos (Astro 450 EW), novaluron (Rimon 100 CE), spinosad (Tracer 480 SC) and triflumuron (Certero as used in corn crops (Zea mays), parent generation females F1 F2 specimens Trichogramma atopovirilia. Eggs Anagasta kuehniella were glued cardstock strips placed under a germicidal lamp kill embryos. These then sprayed with chemical products using...
The chemical control of Spodoptera frugiperda (Lepidoptera: Noctuidae) is difficult because caterpillars live inside the corn (Zea mays) cob and they do not come into contact with insecticides. Research on use parasitoids genus Trichogramma (Hymenoptera: Trichogrammatidae) has contributed to advances in alternatives for this pest. However, there little information effects pesticides used these parasitoids. Therefore, objective study was evaluate physiological selectivity insecticides...
RESUMO A ação residual dos inseticidas imidacloprido/Beta-ciflutrina, clotianidina e clorfenapir foi avaliada para larvas de terceiro ínstar adultos do predador Cycloneda sanguinea (Linnaeus). Sementes algodão da cultivar BRS IPÊ foram semeadas em vasos PVC as plantas mantidas casa vegetação. Ao atingirem 25 dias idade, pulverizadas com os produtos nas menores dosagens recomendadas pelos fabricantes, utilizando-se pulverizador manual. As concentrações g i.a.L-1 água:...
Abstract BACKGROUND Lepidopteran pest control in agriculture has become heavily dependent on cultivars that express Bacillus thuringiensis ( Bt ) toxins as ‘plant‐incorporated protectants’. However, populations of Spodoptera frugiperda (Smith) Brazil appear resistant to the traits currently available commercial soybean cultivars. RESULTS This study evaluated S. life history when feeding three different Cultivars expressing Cry1Ac + Cry1F and Cry1A.105 Cry2Ab2 caused 100% larval mortality ....
This study evaluated the relationship between resistance of Lipaphis pseudobrassicae to parasitoid Diaeretialla rapae and effects insecticide acetamiprid on aphid. Four groups L. collected in Uberlândia, MG, were used. The first two formed by individuals same clone (C1), which resistant (C1R) or susceptible (C1S) parasitoid. third group was descended from a canola (C2R) fourth group, population commercial plantation collard greens (P1). Determination LD50 done with three replications 10...
