New records of natural enemies of Plutella xylostella (L.) (Lepidoptera: Plutellidae) in Pernambuco, Brazil
Provedor de dados: 82
Autores: Silva-Torres,Christian S A; Pontes,Itillio V A F; Torres,Jorge B; Barros,Reginaldo.
We report the occurrence of natural enemies of Plutella xylostela (L.) in organically farmed kale in Pernambuco, Brazil. Seven natural enemies were observed parasitizing or preying on larvae and pupae of P. xylostella - three parasitoids: Cotesia plutellae Kurdjumov (Hym.: Braconidae), Conura pseudofulvovariegata (Becker) (Hym.: Chalcididae) and Tetrastichus howardi (Olliff) (Hym.: Eulophidae), and four predators: Cheiracanthium inclusum (Hentz) (Araneae: Miturgidae), Pheidole sp.Westwood (Hym.: Formicidae), nymphs and adults of Podisus nigrispinus (Dallas) (Hem.: Pentatomidae), and one unidentified species of solitary wasp. Beyond recording these natural enemies, data on predation of P. xylostella larvae in the field and laboratory by C. inclusum are...

Biological control of fruit flies in Brazil
Provedor de dados: 86
Autores: Paranhos,Beatriz Jordão; Nava,Dori Edson; Malavasi,Aldo.
Abstract: Fruit flies are the main pests of fruit growing in Brazil. They have been managed predominantly with the use of insecticides applied as cover spray and or/as toxic baits. Currently, the trend of management strategies is toward the adoption of methods that cause the lowest environmental impact in large areas. In this context, biological control is an excellent option to be used together with other management strategies, such as sterile insects, because it leaves no residues, does not disturb nontarget pests, and can be permanent if the natural enemy establishes itself in the field. This review paper addresses the current knowledge on the biological control of fruit flies in Brazil, highlighting the great biodiversity of its natural enemies,...

Forest fragments' contribution to the natural biological control of Spodoptera frugiperda Smith (Lepidoptera: Noctuidae) in Maize
Provedor de dados: 52
Autores: Sousa,Eduardo Henrique Santana; Matos,Michela Costa Batista; Almeida,Ruanno Silva; Teodoro,Adenir Vieira.
The present work evaluated the influence of forest distance on predatory solitary wasps' abundance and richness and its relation to the natural biological control of the fall armyworm (Spodoptera frugiperda Smith - Lepidoptera: Noctuidae) in maize. The study consisted of two parallel lines of six experimental maize plots located at an increasing distance from a forest edge. Four trap-nests were placed in the vertices of each plot of the first line to evaluate the abundance and species richness of predatory solitary wasps. The larvae of the fall armyworm were sampled weekly by inspecting ten randomly chosen plants per plot. Predatory solitary wasp abundance (but not species richness) decreased whilst the fall armyworm abundance increased with the distance...

Incidence of Mythimna sequax parasitized in wheat crop
Provedor de dados: 65
Autores: Bortolotto,Orcial Ceolin; Menezes Júnior,Ayres de Oliveira; Hoshino,Adriano Thibes; Salgado-Neto,Geraldo.
ABSTRACT: This study investigated the natural parasitism of Mythimna sequax Franclemont, 1951, in wheat during the crop season of 2008. In total, 237 larvae were captured, of which 10.12% were parasitized. The Tachinidae species Winthemia trinitatis (Thompson, 1963), Winthemia tricolor (Wulp, 1890), Lespesia aletiae (Riley, 1879), and Lespesia archippivora Beneway, 1963 are reported for the first time parasitizing the wheat armyworm in Brazil. In addition, two other genus of parasitoids were identified, one Tachinidae Peleteria Robineau-Desvoidy, 1830 and one Ichneumonidae Ophion (Fabricius, 1798). This study reported for the first time four Tachinidae species parasitizing W. sequax, and further studies are needed to promote the conservation of these...
