The large-scale production of Baculovirus to control fall armyworm, Spodoptera frugiperda, presents many limitations. The most important limiting factor is that the baculovirus, which infects fall armyworm, causes liquefaction of the integument immediately after death. This disruption of the integument difficultates the large scale production because dead insect must be frozen before being harvested. This fact implies in high lab work need, increasing the cost of the biopesticide. This problem was overcome by the discovery of a new baculovirus nucleopolyhedrovirus (NPV) isolate in Cascavel/PR, that doesn?t cause liquefaction of the integument (isolate 6NR) immediately after the insect death. This is an extremely important factor in a large-scale...

Aerial, ground and chemigation spray deposition on corn for the control of spodoptera frugiperda (lepidoptera: noctuidae)

Ciência e Agrotecnologia

Cunha,João Paulo Arantes Rodrigues da; Nascimento,Ana Paula de Castro.

Pesticides can be applied by aircraft, ground-sprayers or sprinkler irrigation. However, selecting the best option is complicated by the limited number of studies comparing these techniques. Thus, the objective of this work was to study the chlorpyrifos insecticide deposition applied by aircraft (30 L ha-1), tractor-mounted sprayer (200 L ha-1) and chemigation (70,000 L ha-1) for the control of Spodoptera frugiperda (J.E. Smith) in two corn (Zea mays L.) populations (70,000 and 100,000 plants ha-1). Active ingredient residue on the corn plant leaves was evaluated by gas chromatography, immediately and ten days after the treatments. Armyworm numbers in each plot and control were also evaluated. The experiment was set up in randomized blocks with four...

Different concentrations of nuclear polyhedrosis virus were applied as aqueous suspensions using a tractor mounted or a backpack-manual sprayer to control Spodoptera frugiperda (Smith) larvae on maize (Zea mays L.). Larval mortality varied with the application equipment. For the tractor-mounted sprayer application of at least 2.5 x 10(12) P.I.B./ha was necessary to attain a control comparable to that obtained with the backpack-manual sprayer application (70.2%). For this application method it can be used the dose of 2.5 x 10(11) PI.B./ ha, butNPV persistence was very short. A greaterNPV persistence was obtained with doses over 1.25 x 10(12) P.I.B./ha (93.4% mortality). The occurrence of parasitoids in the experimental area increased larval mortality rate...

The insecticidal properties of water-extract of Peumus boldus Molina and its effect on the development cycle and feeding habits of Spodoptera frugiperda J.E. Smith and Helicoverpa zea Boddie were evaluated under laboratory conditions in concentrations of 0.25, 0.5, 1.0, 2.0, 4.0, and 8.0% (w/w). Spodoptera frugiperda was the most susceptible with 75% mortality at 7 d at 8% P. boldus concentration, while H. zea had only 30% mortality. LC50 was 2.31 mL kg-1 for S. frugiperda and 16.05 mL kg¹ for H. zea. When the extract concentration increased in the diet, larval size and weight, percentage of pupation and number of adults decreased, and the time required to reach those states was greater. Neonate larvae fed primarily on the diet with the lower extract...

ABSTRACT: Spodoptera frugiperda (J. E. Smith) is the main target pest of Bt corn technologies, such as YieldGard VT PRO(tm) (Cry1A.105/Cry2Ab2) and PowerCore(tm) (Cry1A.105/Cry2Ab2/Cry1F). In this study, it was evaluated the biological activity of Bt proteins expressed in different plant structures of YieldGard VT PRO(tm) and PowerCore(tm) corn against S. frugiperda . Complete mortality of S. frugiperda neonates was observed on leaf-disc of both Bt corn technologies. However, the mortality in silks and grains was lower than 50 and 6%, respectively. In addition, more than 49% of the surviving larvae in silks and grains completed the biological cycle. However, all life table parameters were negatively affected in insects that developed in silks and grains...

The bacterium Bacillus thuringiensis (Bt) is a promising control agent of Spodoptera frugiperda (J.E. Smith). Besides the lethal effect on hosts, the entomopathogen may cause physiological alterations that hinder insects' feeding intake and reproduction. Larval and female pupa weight, oviposition and egg fecundity were determined in second instar S. frugiperda larvae infected with 39 Bt isolates in four bioassays. Sublethal effects were observed in the follow isolates: ESALQ 1.1, ESALQ 1.4, ESALQ 1.6, ESALQ 3.7, ESALQ 4.2 and ESALQ 5.2 (larval and female pupae weight); ESALQ 5.1 (larval weight); ESALQ 1.2 and ESALQ 3.7 (egg fecundity); ESALQ 3.7 (oviposition and egg fecundity); ESALQ 3.7 and ESALQ 5.2 (oviposition).

Verificou-se o potencial de parasitismo de Campoletis flavicincta (Ashmead) (Hymenoptera: Ichneumonide) sobre lagartas de Spodoptera frugiperda (Smith) de diferentes idades e o consumo foliar de lagartas parasitadas, em relacao a nao parasitadas. Quando foram oferecidas ao parasitoide lagartas de 3-d o numero medio de lagartas parasitadas foi de 232/femea, numero semelhante ao que foi obtido com lagartas de 2-d (182,0 lagartas/femea). Com lagartas de 4-5-d, o numero medio de parasitismo foi, respectivamente, 80,7 e 71,0 individuos parasitados/femea. Lagarta sadias, durante todo o seu periodo de vida, consumiram, em media, 209,3 cm3 de area foliar, enquanto que as lagartas parasitadas consumiram apenas 14,5 cm3 (6,9% do consumo de uma lagarta sadia).
