Within-plant distribution of the leaf miner Tuta absoluta (Meyrick) immatures in processing tomatoes, with notes on plant phenology
This study was carried out to evaluate site preference of tomato leaf miner, Tuta absoluta (Meyrick) (Lepidoptera: Gelechiidae), developmental stages on processing tomatoes. Eggs, first- and… Expand

Interactions of Bacillus thuringiensis Cry1Ac toxin in genetically engineered cotton with predatory heteropterans
A number of cotton varieties have been genetically transformed with genes from Bacillus thuringiensis (Bt) to continuously produce Bt endotoxins, offering whole plant and season-long protection… Expand

Spermatogenesis, changes in reproductive structures, and time constraint associated with insemination in Podisus nigrispinus.
Males of the predatory stinkbug, Podisus nigrispinus (Dallas) (Hemiptera: Pentatomidae), accomplish long and multiple matings. We hypothesize that this behavior is due to time requirement for… Expand

Expression of Bacillus thuringiensis Cry1Ac protein in cotton plants, acquisition by pests and predators: a tritrophic analysis
1. Studies have shown that Cry proteins of the bacterium Bacillus thuringiensis expressed in transgenic plants can be acquired by nontarget herbivores and predators. A series of studies under field… Expand

Recruitment of aphidophagous arthropods to sorghum plants infested with Melanaphis sacchari and Schizaphis graminum (Hemiptera: Aphididae)
A significant question in biological control is the extent to which indigenous natural enemies might be pre-adapted to exploit invasive species that constitute novel prey. We observed the recruitment… Expand

Toxicity of thiamethoxam and imidacloprid to Podisus nigrispinus (Dallas) (Heteroptera: Pentatomidae) nymphs associated to aphid and whitefly control in cotton
The toxicity of thiamethoxam and imidacloprid to Podisus nigrispinus (Dallas) nymphs, and their efficacy against whitefly and cotton aphid were studied. Thiamethoxam and imidacloprid were 217.6 and… Expand

[Compared biology and behavior of Tetranychus urticae Koch (Acari: Tetranychidae) and Phytoseiulus macropilis (Banks) (Acari: Phytoseiidae) on Bollgard and non-transgenic isoline cotton].
The two spotted spider mite, Tetranychus urticae Koch, is a nontarget herbivore of Bt-cotton, but acquires and accumulates higher levels of Cry toxin than that expressed by transgenic plants. This… Expand

Comportamento de predação e conversão alimentar de Podisus nigrispinus sobre a traça-do-tomateiro
This work aimed to determine the predatory behavior of nymphs and adults of Podisus nigrispinus (Dallas) and its reproduction preying upon Tuta absoluta (Meyrick) under open sided greenhouse (30±5oC,… Expand

Efeito das plantas do algodoeiro e do tomateiro, como complemento alimentar, no desenvolvimento e na reprodução do predador Podisus nigrispinus (Dallas) (Heteroptera: Pentatomidae)
The occasional feeding on plants by Podisus nigrispinus (Dallas) has produced different responses on its biology according to the plant species available. This study was undertaken to determine the… Expand

Indigenous Aphid Predators Show High Levels of Preadaptation to a Novel Prey, Melanaphis sacchari (Hemiptera: Aphididae)
ABSTRACT The performance of four aphid predators, Hippodamia convergens Guerin-Meneville, Coleomegilla maculata DeGeer, Chrysopeda carnea Stephens and Orius insidiosus Say was compared on three… Expand
