Provedor de dados: 82
Autores: Bellini,Marcos R; Araujo,Ralf V de; Silva,Edmilson S; Moraes,Gilberto J de; Berti Filho,Evoneo.
Several annual and perennial crops are severely attacked by mites from the family Eriophyidae, Tenuipalpidae and Tetranychidae. A suitable alternative commonly used in several countries for the control of these pest mites involve the use of predatory mites in the family Phytoseiidae. The phytoseiid fauna in the Brazilian natural vegetation is very rich, but nothing is known about the biology of most of these species, as it is the case with Proprioseiopsis cannaensis (Muma). The objective of this study was to determine biological parameters of P. cannaensis fed on pest mite species such as Phyllocoptruta oleivora (Ashmead) (Eriophyidae), Brevipalpus phoenicis (Geijskes) (Tenuipalpidae) and Tetranychus urticae Koch (Tetranychidae). To enable a comparison for...

Autores: Sousa,Josilene M de; Gondim Jr,Manoel G C; Lofego,Antônio C.
The mite Tetranychus mexicanus (McGregor) is considered a pest of a variety of plant species in the Americas. Although this mite apparently causes economic damage to Annonaceae, little is known about its biology. Here we studied the biology of T. mexicanus on soursop (Annona muricata), sweetsop (Annona squamosa) and araticum (Annona coriaceae). The first two species are the most important economical Annonaceae species in northeast Brazil; araticum is commonly found in the region, but not commercially explored. The mites were collected in the field from leaves of A. muricata and maintained in the laboratory for six months on detached leaves of A. muricata, A. squamosa and A. coriaceae, respectively, before observations started. Tetranychus mexicanus...

Provedor de dados: 86
Autores: Silva,Cleonor Cavalcante Alves; Laumann,Raul Alberto; Moraes,Maria Carolina Blassioli; Aquino,Michely Ferreira Santos de; Borges,Miguel.
The objective of this work was to compare the biology of Chinavia impicticornis and C. ubica (Hemiptera: Pentatomidae), two species of stinkbugs that occur as secondary pests in soybean. Life table procedures were used for evaluating nymphs, and fecundity tables for evaluating adults, in order to establish the demographics of the two species. The two species have similar demographic parameters, and the development of immature stages, from egg to adult, had similar duration periods of approximately 30 days. In both species, eggs and second-instar nymphs were the stages with higher mortality. Total egg production did not differ between females of both species. Fecundity and survival curves for adults showed similar trends in both species. However, C. ubica...

Autores: de Castro-Guedes,Camila Fediuk; de Almeida,Lúcia Massutti; do Rocio Chiarello Penteado,Susete; Moura,Mauricio Osvaldo.
ABSTRACT The biology, reproductive variables and population growth indicators of Harmonia axyridis (Pallas, 1773) (Coleoptera: Coccinellidae) fed on three diets, namely Cinara atlantica (Wilson, 1919) (Hemiptera: Aphididae), Brevicoryne brassicae (Linnaeus, 1758) (Hemiptera: Aphididae), and frozen eggs of Anagasta kuehniella (Zeller, 1879) (Lepidoptera: Pyralidae), were evaluated. With all three diets, birth rate was higher than mortality, resulting in positive rm values and thus indicating population growth. Under the conditions used in the experiments, H. axyridis was able to survive, develop and reproduce normally. This demonstrates that are different kind of food that can be essential for supporting the reproduction of some species of Coccinellidae,...
