Against the introduction of natural enemies of plant pests
Fruit is very good. Cultivation of fruit trees are now being developed. Minge is a very troublesome that pest of corn growers, and red with the natural enemies of bees is Minge. In 21,301 years, France has 5O million hectares of corn fields to receive anti Minge protection. Of which 6.5 million hectares, that is, by more than 10% of the corn is this little insect Hymenoptera (Vespidae). The technology is not complicated. Corn is placed in the envelope containing parasitoid larvae, the larvae hatch in the adult the right time. Then the larvae will find the Minge parasitic eggs on top, which will destroy the latter. Biological Pioneer (BiotoP) manager FirouzKabirj said. a group of two to three weeks after the activities of the larvae, Spread of insects in the spread of the appropriate date to be very careful when, which means that not even finish up the envelope thrown on the ground, but to place it in a paper cone, then the paper cone to 3oo per hectare The density of a coating fixed to the corn by hand on the plants. Specific date to spread the larval development cycle based on accumulated temperature and tracking to decide. To this end, R & D company from storage in the nests began to cultivate stem insects. Moth will continue to monitor the temperature of the growth and accumulation. Technology development in the greenhouse was taken not only of corn using natural enemies to eradicate pests, plant protection methods. BiotoD also introduced to the producers of some of the aphids for the elimination of greenhouse ladybug. C3 ~ L (fruits and vegetables cross-industry technology centers) and one Atlantic Loire (Loire --- Aflantique) Province, several farmers groups to assist the development of insects, based on the development of greenhouse tomato and cucumber for a similar technology. The purpose of this measure is that McNair biological methods (secondary spread of insects) and chemical treatment of the most effective combination. Place a bag of tomatoes per plant insect feet can ensure that a greenhouse six to eight Inst without incident. Today, the cucumber's four major insect pests are available through aid or assistance under control ticks and mites. With meat ticks wax fruit farming, the use of natural enemies around the elimination of a certain type of specific pests can be carried out many real agility test, an agricultural technical cooperation in the Association of AcrA, especially = for example, the association had to deal with apple The red test conducted Acari. disasters, former head of OmerBaudry Technology Center in the nineties to take some measures to bow f into a species from Italy b III A charge seius carp. dersoni. just the beginning of the trials did not achieve any results. But During the same period, growing health-care project strategy has changed, the new strategy to reduce the use of chemical pesticides,[link widoczny dla zalogowanych], which drives our orchards nurtured many kinds of meat ticks and mites. According to the statistics. a total of l3 kinds of TyphlodromusP Ⅵ i and A a yseiusandcr.soni. after the start of the trial, particularly resistant to Amblv-se [usanderson [the test, and achieved great results. Park, to 2002, the trial will be extended to ten orchards Preliminary results from such comments, but still very good. ※ Thin Gap Technology
