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: Making lightweight construction suitable for series production

More and more automobile companies are focusing on body parts made of carbon fiber reinforced plastics (CFRP). However, manufacturing and repair costs must be further reduced in order to make CFRP more economical in use. Together with the Volkswagen AG and five other partners in the project HolQueSt 3D, the Laser Zentrum Hannover e.V. (LZH) has developed laser processes for the automatic trimming, drilling and repair of three-dimensional components.

Automated manufacturing processes are the basis for ultimately establishing the series production of CFRP components. In the project HolQueSt 3D, the LZH has...

Im Focus: Wonder material? Novel nanotube structure strengthens thin films for flexible electronics

Reflecting the structure of composites found in nature and the ancient world, researchers at the University of Illinois at Urbana-Champaign have synthesized thin carbon nanotube (CNT) textiles that exhibit both high electrical conductivity and a level of toughness that is about fifty times higher than copper films, currently used in electronics.

"The structural robustness of thin metal films has significant importance for the reliable operation of smart skin and flexible electronics including...

Im Focus: Deep inside Galaxy M87

The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.

Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...

Im Focus: A Quantum Low Pass for Photons

Physicists in Garching observe novel quantum effect that limits the number of emitted photons.

The probability to find a certain number of photons inside a laser pulse usually corresponds to a classical distribution of independent events, the so-called...

Im Focus: Microprocessors based on a layer of just three atoms

Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.

Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...
