Aim of study: Assessment toxicity and sublethal effects registered insecticides currently used in strawberry cultivation Brazil on Trichogramma pretiosum Riley adults.Area The study was conducted under laboratory conditions Paraná (Brazil).Material methods: Previously non-parasitized Duponchelia fovealis Zeller (Lepidoptera: Cambridae) eggs were dipped into insecticide dilutions or control solu...

The ongoing loss of global biodiversity is endangering ecosystem functioning and human food security. While environmental pollutants are well known to reduce fertility, the potential effects common neonicotinoid insecticides on insect fertility remain poorly understood. Here, we show that field-realistic exposure can drastically impact male fertility. In laboratory, female solitary bees Osmia c...

Processes on wastewater treatment plants (WWTP) are not always efficient for pollutant removal. A new, low-cost, and effective technology is needed. In this work, the photocatalytic degradation of four insecticides, chlorantraniliprole, imidacloprid, pirimicarb, thiamethoxam, has been examined in different water matrices (irrigation water, leaching waters, WWTP effluent). Lab experiments were c...

ABSTRACT: We evaluated under field conditions the toxicity of insecticides previously identified as harmful in laboratory and semifield bioassays on parasitoid Trichogramma pretiosum (Hymenoptera: Trichogrammatidae). The experiments were conducted during 2019/20 2020/21 harvests rice fields. Following recommendations International Organization for Biological Integrated Control (IOBC), four appl...

Regarding the hypothesis that neonicotinoid insecticides used for seed coating of agricultural crops - mainly corn, sunflower and seed rape - are related to the extensive death of honey bees, the phenomenon of corn seedling guttation has been recently considered as a possible route of exposure of bees to these systemic insecticides. In the present study, guttation drops of corn plants obtained ...

European governments have banned the use of three common neonicotinoid pesticides due to insufficiently identified risks to bees. This policy decision is controversial given the absence of clear consistency between toxicity assessments of those substances in the laboratory and in the field. Although laboratory trials report deleterious effects in honeybees at trace levels, field surveys reveal ...

There is considerable and ongoing debate as to the harm inflicted on bees by exposure to agricultural pesticides. In part, the lack of consensus reflects a shortage of information on field-realistic levels of exposure. Here, we quantify concentrations of neonicotinoid insecticides and fungicides in the pollen of oilseed rape, and in pollen of wildflowers growing near arable fields. We then comp...

The midge Contarinia nasturtii (Keiffer), a serious gall-forming insect pest of cruciferous plants in Europe and southwestern Asia, was Þrst reported in the United States in summer 2004. It had not been recorded in North America until its discovery in Ontario, Canada, in 2000. EfÞcacy of 20 insecticides belonging to 12 different classes was evaluated by using a foliar spray, soil drench, or see...
