In order to contribute to taxonomic information on Tetranychid mites (Acari: Tetranychidae) in South America, surveys were conducted in Brazil (15 States and the Federal District) and Uruguay (one Department); 550 samples of 120 plant species were collected. Tetranychid mite infestations were confirmed in 204 samples, and 22 species belonging to seven genera of the Bryobiinae and Tetranychinae ...

In this study, lambda-cyhalothrin (LC) used as a pesticide was microencapsulated with polyurethaneurea (PUU) at 55°C temperature for 180 min. Wall thickness and dimensions of the microcapsules, effect mixing speed on capsule size, active substance release times LC-PUU microencapsules under UV rays alcohol/water medium, microencapsulation yields red spider peppermint plant leaves (mentha piperit...

Methods Patients from Southern Romania with grass pollen rhinitis, diagnosed by allergy evaluation with positive skin prick tests and high serum levels of specific IgE to Pooideae pollen, were screened for food allergy by detailed clinical history of symptoms related to maize-derived edible products, including foods with corn as basic ingredient, such as polenta, porridge, cornflakes, tortilla ...

A single laboratory study on monarch butterflies has prompted widespread concern that corn pollen, engineered to express Bacillus thuringiensis (Bt) endotoxin, might travel beyond corn fields and cause mortality in nontarget lepidopterans. Among the lepidopterans at high potential risk from this technology is the black swallowtail butterfly, Papilio polyxenes, whose host plants in the midwester...

1 Coleomegilla maculata DeGeer feeds on corn pollen in the field, but the degree to which this predator relies on corn pollen as part of its diet is not well understood. We quantified the amount of pollen consumed by C. maculata second, third and fourth instars and adults in the field. 2 Laboratory experiments were conducted to determine the digestion rate and duration of different stadia or st...

tetranychus urticae koch is an injurious pest of, fruit crops, crop plants as well as ornamental plants worldwide. the high reproductive potential of t. urticae and its fairly short life cycle along with the frequent application of acaricides usually required to maintain t. urticae populations below economic thresholds, facilitates the pest's resistance to acaricides, and consequently cont...

the two-spotted spider mite, tetranychus urticae koch (acari: tetranychidae) is one of the most important agricultural pests of the world. it causes direct and indirect damage on plants which decreases in photosynthesis and crop yield. the effect of sublethal concentrations of artemisia annua l. (asteraceae) and rosmarinus officinalis l. (lamiaceae) essential oils were assessed on development a...
