Bioinsecticide for controlling plagues in greenhouses

17.06.2004


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: A step towards controlling spin-dependent petahertz electronics by material defects

The operational speed of semiconductors in various electronic and optoelectronic devices is limited to several gigahertz (a billion oscillations per second). This constrains the upper limit of the operational speed of computing. Now researchers from the Max Planck Institute for the Structure and Dynamics of Matter in Hamburg, Germany, and the Indian Institute of Technology in Bombay have explained how these processes can be sped up through the use of light waves and defected solid materials.

Light waves perform several hundred trillion oscillations per second. Hence, it is natural to envision employing light oscillations to drive the electronic...

Im Focus: Freiburg researcher investigate the origins of surface texture

Most natural and artificial surfaces are rough: metals and even glasses that appear smooth to the naked eye can look like jagged mountain ranges under the microscope. There is currently no uniform theory about the origin of this roughness despite it being observed on all scales, from the atomic to the tectonic. Scientists suspect that the rough surface is formed by irreversible plastic deformation that occurs in many processes of mechanical machining of components such as milling.

Prof. Dr. Lars Pastewka from the Simulation group at the Department of Microsystems Engineering at the University of Freiburg and his team have simulated such...

Im Focus: Making the internet more energy efficient through systemic optimization

Researchers at Chalmers University of Technology, Sweden, recently completed a 5-year research project looking at how to make fibre optic communications systems more energy efficient. Among their proposals are smart, error-correcting data chip circuits, which they refined to be 10 times less energy consumptive. The project has yielded several scientific articles, in publications including Nature Communications.

Streaming films and music, scrolling through social media, and using cloud-based storage services are everyday activities now.

Im Focus: New synthesis methods enhance 3D chemical space for drug discovery

After helping develop a new approach for organic synthesis -- carbon-hydrogen functionalization -- scientists at Emory University are now showing how this approach may apply to drug discovery. Nature Catalysis published their most recent work -- a streamlined process for making a three-dimensional scaffold of keen interest to the pharmaceutical industry.

"Our tools open up whole new chemical space for potential drug targets," says Huw Davies, Emory professor of organic chemistry and senior author of the paper.
