Bioinsecticide for controlling plagues in greenhouses


Developing a bioinsecticide that is more effective than pesticides for controlling pests in greenhouses is the aim of the project undertaken by a research team from the Public University of Navarre and commissioned by the Almería Fruit & Vegetable Exporters Association (COEXPHAL).

Biological efficiaciousness

The COEXPHAL Association of the province of Almería manages a surface area of about 18,000 hectares, primarily given over to greenhouse vegetables. Many of these crops (peppers, tomato, watermelon, melon, marrow, cucumber, beans and aubergine) have associated plant health problems that have an important impact on production costs. Some of the more serious problems in this respect originate in the larvae of the Llepidoptera Spodoptera exigua.

However, there is no commercial biological product that is currently effective in the control of this insect. The Public University of Navarre has developed a bioinsecticide for COEXPHAL based on isolated elements of the S. exigua nucleopolyhedrovirus which, after undertaking experimental tests, have proved to be more efficient in controlling pests than chemical pesticides.

It should be pointed out that the control of this insect by means of the application of chemical pesticides in greenhouses of the Association costs more than six million euros annually and does not enable the desired results to be obtained due to the serious problems of resistance to this pest.

Rise in bioinsecticides

The development of bioinsecticides has become more relevant in recent years, given that the interest shown by growers and companies is ever greater - the pests producing negative effects on health and on the quality of the environment.

In concrete, bioinsecticides based on baculovirus, given its characteristics of safety, efficiency and specificity, are ideal biological pest control agents for inclusion in integrated control programmes. Moreover, their insecticide action is especially useful against those plant-devouring species that have developed multiple resistance to chemical pesticides.

In the development of the bioinsecticide object of this project, isolated S. Exigua multiple nucleopolyhedrovirus has been obtained from dead larvae from a number of different habitats - natural epizootic ones.

Im Focus: Diamonds aren't forever: Sandia, Harvard team create first quantum computer bridge

By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.

"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...

Im Focus: Ultra-thin ferroelectric material for next-generation electronics

'Ferroelectric' materials can switch between different states of electrical polarization in response to an external electric field. This flexibility means they show promise for many applications, for example in electronic devices and computer memory. Current ferroelectric materials are highly valued for their thermal and chemical stability and rapid electro-mechanical responses, but creating a material that is scalable down to the tiny sizes needed for technologies like silicon-based semiconductors (Si-based CMOS) has proven challenging.

Now, Hiroshi Funakubo and co-workers at the Tokyo Institute of Technology, in collaboration with researchers across Japan, have conducted experiments to...
