Scientists of the UGR obtain a bioinsecticide to control the Mediterranean fruit fly

23.10.2009
This is an environmentally friendly technique, non-toxic, easy to produce, which can also be supplied by conventional methods.

The Mediterranean fruit fly, Ceratitis capitata, is a world plague which represents one of the most serious problems for agriculture. However, the control methods currently present in the market for this plague are ineffective.

The research group of the Institute of Biotechnology of the University of Granada (Spain) has isolated and identified a stump of the genus Bacillus, extremely toxic for larvae of C. capitata. After subjecting such stump to a specific treatment, protected by a patent, we have managed to increase notably its toxicity against this fly.

According to Dr. Susana Vilchez (hired by the Ramón y Cajal), the Mediterranean fruit fly has a special economic relevance in the Mediterranean countries, like Spain. Given the capacity of the C. capitata to tolerate colder climates than the rest of the species of flies and their wide range of host plants, the C. capitata has been considered as one of the most important species from the point of view of economy. This plague attacks more than 260 species of fruits, flowers or nuts of agricultural fruits and it has been estimated that causes losses assessed in hundreds of millions of dollars annually in the countries where it settles.

Biological alternative
Chemical insecticides such as malatión have been traditionally used, but they are not effective for the control of the C. capitata. In addition, their use presents a series of drawbacks such as environmental pollution, dangerousness for the staff, the need of safety periods before the commercialization of the fruit, insects-resistance phenomena, etc.

As the European legislation is getting increasingly strict with regard to the use of chemical insecticides –the use of malatión is forbidden since June of 2007-, the alternative of biological control is gaining prominence and is becoming a new exploitation field.

In this sense, the results obtained by the scientists from Granada are promising, as at present there is not any bio-insecticide in the market based on bacteria and active against this plague. In addition, this is a new technique for the of the Mediterranean fruit fly, environmentally friendly, non-toxic, easy to produce, and can be supplied by conventional methods.

The researchers maintain that the development of a commercial product based on these bacteria will mean an important advance for the agricultural industry.

Im Focus: Temperature-controlled fiber-optic light source with liquid core

In a recent publication in the renowned journal Optica, scientists of Leibniz-Institute of Photonic Technology (Leibniz IPHT) in Jena showed that they can accurately control the optical properties of liquid-core fiber lasers and therefore their spectral band width by temperature and pressure tuning.

Already last year, the researchers provided experimental proof of a new dynamic of hybrid solitons– temporally and spectrally stationary light waves resulting...

Im Focus: AchemAsia 2019 will take place in Shanghai

Moving into its fourth decade, AchemAsia is setting out for new horizons: The International Expo and Innovation Forum for Sustainable Chemical Production will take place from 21-23 May 2019 in Shanghai, China. With an updated event profile, the eleventh edition focusses on topics that are especially relevant for the Chinese process industry, putting a strong emphasis on sustainability and innovation.

Founded in 1989 as a spin-off of ACHEMA to cater to the needs of China’s then developing industry, AchemAsia has since grown into a platform where the latest...

Im Focus: First real-time test of Li-Fi utilization for the industrial Internet of Things

The BMBF-funded OWICELLS project was successfully completed with a final presentation at the BMW plant in Munich. The presentation demonstrated a Li-Fi communication with a mobile robot, while the robot carried out usual production processes (welding, moving and testing parts) in a 5x5m² production cell. The robust, optical wireless transmission is based on spatial diversity; in other words, data is sent and received simultaneously by several LEDs and several photodiodes. The system can transmit data at more than 100 Mbit/s and five milliseconds latency.

Modern production technologies in the automobile industry must become more flexible in order to fulfil individual customer requirements.

Im Focus: Sharp images with flexible fibers

An international team of scientists has discovered a new way to transfer image information through multimodal fibers with almost no distortion - even if the fiber is bent. The results of the study, to which scientist from the Leibniz-Institute of Photonic Technology Jena (Leibniz IPHT) contributed, were published on 6thJune in the highly-cited journal Physical Review Letters.

Endoscopes allow doctors to see into a patient’s body like through a keyhole. Typically, the images are transmitted via a bundle of several hundreds of optical...
