Abstract: The feeding and oviposition behavior of boll weevil in new cotton cultivars is essential for an adequate management. The objective of this study was to evaluate the vertical distribution of squares punctured for feeding and oviposition of the pest in the cultivars NuOPAL, DeltaOPAL, FMT-701, FMX-910 and FMX-993, and record the most and least preferred times of feeding and oviposition. The number of squares used for boll weevil feeding and oviposition were evaluated weekly in three parts of plant canopy. It was observed that, regardless the cultivar, A. grandis preferred to lay eggs in squares located in the upper part and feed on squares in the middle and upper parts. The boll weevil preferred to feed on cultivar FMT-701 in the beginning of the period of cotton flowering and fruiting, and the cultivars NuOPAL, DeltaOPAL, FMX-910 and FMX-993 throughout the whole period of flowering and fruiting. A. grandis preferred to lay eggs on cultivars NuOPAL, FMT-701 and FMX-993 at the beginning and end of flowering and fruiting of plants, while the cultivars DeltaOPAL and FMX-910 are used for oviposition throughout the period of flowering and fruiting. O conhecimento do comportamento de alimenta o e de oviposi o de Anthonomus grandis em cultivares recentes de algodoeiro é essencial para seu manejo. Neste trabalho, objetivou-se avaliar a distribui o vertical de bot es florais com orifícios de alimenta o e de oviposi o da praga nas cultivares NuOPAL, DeltaOPAL, FMT-701, FMX-910 e FMX-993, bem como registrar as épocas de maior e menor preferência alimentar e de oviposi o. O experimento foi conduzido em Jaboticabal, SP, Brasil, safra 2010/2011. Foram realizadas avalia es semanais, baseadas no número de bot es florais, utilizados para alimenta o e para oviposi o pelo bicudo-do-algodoeiro, em três regi es do dossel das plantas. Observou-se que A. grandis preferiu ovipositar em bot es florais localizados no ter o superior das plantas e se alimentar de bot es florais localizados nos ter os médio e superior das plantas. A cultivar FMT-701 foi mais utilizada para a alimenta o do bicudo, no início do período de florescimento e frutifica o, e as cultivares NuOPAL, DeltaOPAL, FMX-910 e FMX-993 s o utilizadas em todo o período de florescimento e frutifica o das plantas. A. grandis preferiu ovipositar nas cultivares NuOPAL, FMT-701 e FMX-993, no início e no final do período de florescimento e frutifica o e as cultivares DeltaOPAL e FMX-910 foram mais ovipositadas durante todo o período de florescimento e frutifica o das plantas.

Abstract: Okadaic acid (OA) and its analogues, dinophysistoxin 1 (DTX1) and dinophysistoxin 2 (DTX2), are lipophilic and heat-stable marine toxins produced by dinoflagellates, which can accumulate in filter-feeding bivalves. These toxins cause diarrheic shellfish poisoning (DSP) in humans shortly after the ingestion of contaminated seafood. Studies carried out in mice indicated that DSP poisonous are toxic towards experimental animals with a lethal oral dose 2–10 times higher than the intraperitoneal (i.p.) lethal dose. The focus of this work was to study the absorption of OA, DTX1 and DTX2 through the human gut barrier using differentiated Caco-2 cells. Furthermore, we compared cytotoxicity parameters. Our data revealed that cellular viability was not compromised by toxin concentrations up to 1 μM for 72 h. Okadaic acid and DTX2 induced no significant damage; nevertheless, DTX1 was able to disrupt the integrity of Caco-2 monolayers at concentrations above 50 nM. In addition, confocal microscopy imaging confirmed that the tight-junction protein, occludin, was affected by DTX1. Permeability assays revealed that only DTX1 was able to significantly cross the intestinal epithelium at concentrations above 100 nM. These data suggest a higher oral toxicity of DTX1 compared to OA and DTX2.
