In recent years, with the improvement of the ecological environment and the enhancement of people's awareness of environmental protection, birds have
become more and more, and even become a disaster. In Agriculture, airports, electricity and other fields have suffered greatly, and birds striking aircrafts
are the most serious one among the bird hazards.
1. Overview of the other bird repellent products which are commonly used in China:
Bird repellent, as a kind of bird behaviour change agent, now has become one of the integrated management method to prevent birds striking aircrafts at airports and is widely used in China. However, the country has not yet formulated a unified industry standard for bird repellent products, the effective composition formula of bird repellent from various enterprises are varied. Many manufacturing enterprises are driven by profits, and they have no careful and serious scientific attitude to carry out experimental studies and repeated field trail tests. Some manufacturing enterprises just copy someone else's patent results in inferior products, and their repellent composition formulations do not take adequate account of the interactions between aromatic compounds. Although their products can temporarily drive away part of the birds after application, but the side effect is to attract a large number of flying insects, which will cause the increase of birds quantity in the treated area due to more and more flying insects. In the past several years, many airports have applied these inferior bird repellent products which increase the frequency of bird striking aircrafts during the take-off and landing, and the outbreak of swallows and bats is the most realistic evidence.
2. The Characteristics of Pestman bird repellent products:
Pestman bird repellent is microcapsule aqueous preparation which is produced by using active ingredients of various biological raw materials which are rich in biological factors for repelling various birds, and it is the real sense of slow-release biological product. The use of aromatic compounds affects the birds in the sense of smell and taste to produce allergic reaction and anorexia reaction, and meanwhile it also affects the birds in the sense of touch to produce a " rejection reaction" function. That is why Pestman bird repellent product has good effect and long effective time. The microcapsule bird repellent suspension emulsion for airport is our flagship product, and it also can be used in livestock farms. It is regarded as the exclusive product that can effectively repel sparrows by many pest control enterprises in China. Pestman bird repellent products takes full account of the interaction among the aromatic compounds, the produced odour after application will not attract flying insects, and even have a repellent and physical killing effect to some insects.
3. Application Scheme of Pestman Bird Repellent at Nanchang Changbei International Airport:
1) Overview of the flight control area:
The runway of the flight control area of Changbei Airport is 3,400 meters length and 60 meters width, the lawn area is nearly 167 hectares. The terrain is basically flat, with few low-lying areas. Outside the perimeter are grass belts, rivers, ponds, large areas of crop planting and small distributed arbor forests, which is the best place for birds to inhabit and insects to breed easily. In the lawn of the flight control area, insects are abundant in Spring, Summer and Autumn, but few in winter. In the season of insect abundance, moths of Lepidoptera and grasshoppers are the most, while beetles of Coleoptera are rare. These insects are the main foraging objects of birds in these three seasons. Although the grass in the flight control area is mowed four times per year on average, the grass seeds grow unevenly and are the food source for the finches that like to eat grass seeds.
2) Insecticide application in the lawn area of the flight control area:
In winter, there are lots of insect eggs in the soil of airport lawns, especially the eggs of locusts which is 5 ~ 8 cm deep from the ground. Airport should
spray the insecticides such as Malathion timely after the first mowing in spring to kill the young Orthoptera and Lepidoptera insects. After mowing, you should also applicate Molluscacide (such as: Metaldehyde) on the low flying areas where snails and other mollusks breed to prevent big waterfowl from harming the airport control area. After each mowing, different insecticides should be sprayed according to the species of insect pests in different seasons to cut off the food source for birds to forage in the earthen lawn area of the airport. The application of insecticides and bird repellent in the flight control area of the airport can get twice the result with half the effort.
3) Application of Pestman bird repellent in flight control areas:
Pestman bird repellent, as one of the measures of comprehensive bird prevention and control in the airport, is the most effective when flock birds disaster occurs in the flight control area. And it can also be a preventive measure if you know the season of airport birds hazard well. According to the characteristics of Pestman bird repellents, the first choice is to spray Bird Repellent Microcapsule Suspension Emulsion (Pestman bird repellent B), and scattering Bird Repellent Microcapsule Granules (Pestman bird repellent G) and putting Bird Repellent Microcapsule Block (Pestman bird repellent M) as auxiliary. Bird Repellent Smoke Fog Agent (Pestman bird repellent E) should be used when there are Swallow hazard and Bat hazard or when the environmental temperature below 0℃ in winter to prevent and control bird hazard. It is suggested to mix Pestman bird repellent B with insecticide, and dilute them with water and spray them on the runway (Swallows like to warm themselves and pick up rubber particles on the runway after dawn) and the lawns on both sides of the runway in the flight control area. If you will use Bird Repellent Smoke Fog Agent (Pestman bird repellent E) to repel the Swallows and Bats, we suggest you to applicate it over the runway and lawns.
4.Conclusion
The application of bird repellents in Changbei Airport will not increase the number of insects due to the application of a series of bird repellent products, because of its unique performance, so that the accident frequency of bird striking aircraft will be reduced, and the cost of other comprehensive bird pest control measures will be reduced.
