Better pollinate seed production plots

July 11, 2018

For several years, the seed and beekeeping sectors have been working to strengthen relations between their two businesses. The latest tool is Beewapi.com, a promising trading platform. Beekeeping and agriculture flourish Bees are crucial for the production of oilseeds (rapeseed, sunflower, etc.), particularly in seed multiplication , where the quality and quantity of the seeds are essential. Pollinating insects participate […]

How to save POLLINATING INSECTS from extinction?

July 1, 2018

In the face of the decline of pollinators, especially insects, there is no miracle recipe, explains Colin Fontaine, from the National Museum of Natural History. However, the more respectful practices of biodiversity that emerged in the 1990s seem to have slowed down this decline in populations. Be careful, however, he explains, because there is a decline in […]

Spider silk: the secrets of its resistance finally revealed

July 1, 2018

Spider silk has exceptional qualities that scientists would like to reproduce. Before that, one must understand the mechanism that governs its formation. And a Japanese team seems to have taken a step further in this direction. Extremely resistant and at the same time, surprisingly flexible, spider silk intrigues as much as it interests the researchers. Because such silk, produced on a […]

BEES understand the concept of ZERO

July 1, 2018

Researchers trained bees to recognize images with the smallest number of elements and showed that they understood the concept of zero. This is surprising for an insect that has less than a million neurons, when the human brain contains 86 billion. The bee is an interesting model for studying the intelligence of insects: they learn from each other […]

Exhibition at Fipronil

June 29, 2018

Exhibition of bees Beekeepers began to suspect the role of Fipronil following the use of Regent TS for the coating of sunflower seed from 1998 onwards. It gradually became apparent that Fipronil used to treat seeds entered the plant well. (of the order of 5% of the quantity applied) and that measurable traces could be found there. On the […]

Fipronil in the wild

June 29, 2018

Beekeepers have been confronted for several years with problems of abnormal mortality of bees. They have been led to suspect the action of insecticides widely used in agriculture. Behavior in plants The manufacturer has since argued that Fipronil is not a systemic insecticide. However, various studies have shown that it can be transported by the sap in the […]

Corn Borer and Resistance to Transgenic Maize

June 28, 2018

Transgenic maize crops producing Bacillus thuringiensis (Bt) toxins  are primarily targeted at a butterfly, the corn borer. These cultures involve monitoring the possible emergence of insects resistant to Bt toxin. The high-dose refuge strategy (HDR), mandatory in the United States and under discussion in Europe, aims to avoid the appearance of this resistance, by promoting genetic mixing in insects. Researchers from […]

How does Bacillus Thuringiensis kill insects?

June 28, 2018

Discovered in 1911, the bacterium Bacillus thuringiensis has been widely used as an insecticide since the 1950s; today it is the leading biological pest control agent for crop pests, particularly the caterpillars of Lepidoptera. In addition, transgenic plants with the toxin gene of this bacterium are the most planted among genetically modified plants. Although this bacterium and the toxin it produces have been studied for many […]

Is a “super-resistant” insect threatening global agriculture?

May 16, 2018

Two insects whose larvae are among the worst pests of agriculture have hybridized. Result: voracious parasites and, especially, multi-resistant to pesticides. What cause considerable agricultural losses. This is a very frightening discovery made by two researchers from the Commonwealth Scientific and Industrial Research Organization (CSIRO), an Australian research organization. Two of the most devastating insects for crops have crossed to give birth to […]
