How to avoid trapping beneficial insects when using trap lights?
Insect traps have been recognized as a powerful tool for trapping and killing pests in agriculture. The insect traps are easy to operate, attract a wide range of pest killers, and are environmentally friendly. They have been widely used throughout the country. Inducing insects in the trapping of pests and colleagues will inevitably seduce some beneficial insects. How do you use insect traps to avoid trapping insects?
Ignoring the analysis of insect traps by some tiny insects requires experts in different fields, and it is very difficult. Some species are small and insignificant in classification and difficult to classify; there are also some tiny insects that are scorched and unrecognizable when they touch the grid, but are ignored. However, these tiny species are often the natural parasites that are important pests. Therefore, there are certain limitations on the statistics of the species of insects and pests.
There are certain limitations in the definition of pests
Now the analysis of the ecological effects of frequent vibration insecticidal lamps, the definition of pests has some limitations. For example, the statistics of pests on a piece of farmland often include some forest pests or other plant pests. However, these species do not necessarily cause harm to the farmland, and their existence may provide certain food sources and intermediate hosts for natural enemies in the farmland, which is beneficial to the maintenance of natural enemy populations; it may also form a competitive relationship with some farmland pests in the niche. It is conducive to the control of farmland pests. Obviously this part of the species should not be simply defined as pests.
Ignored problems in evaluating control effects
Frequency vibration insecticidal lamp plays an important role in adult insect pests and should be evaluated using adult control standards. It includes two aspects: the pest control effect of the same generation and the following generations of pest control effects. For example, the use of frequency-vibration insecticides to control American moths reveals that the adult females have spawned or partially spawned, which means that the adult has been bred to the next generation before being trapped. Therefore, it is also an important factor to evaluate the prevention and control effect of analyzing whether the trapped adult has laid eggs. Most of the evaluations now do not consider this issue.
