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: Electron highway inside crystal

Physicists of the University of Würzburg have made an astonishing discovery in a specific type of topological insulators. The effect is due to the structure of the materials used. The researchers have now published their work in the journal Science.

Topological insulators are currently the hot topic in physics according to the newspaper Neue Zürcher Zeitung. Only a few weeks ago, their importance was...

Im Focus: Significantly more productivity in USP lasers

In recent years, lasers with ultrashort pulses (USP) down to the femtosecond range have become established on an industrial scale. They could advance some applications with the much-lauded “cold ablation” – if that meant they would then achieve more throughput. A new generation of process engineering that will address this issue in particular will be discussed at the “4th UKP Workshop – Ultrafast Laser Technology” in April 2017.

Even back in the 1990s, scientists were comparing materials processing with nanosecond, picosecond and femtosesecond pulses. The result was surprising:...

Im Focus: Novel silicon etching technique crafts 3-D gradient refractive index micro-optics

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.

Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...

Im Focus: Quantum Particles Form Droplets

In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.

“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
