Insect lamp has been recognized as a weapon to trap pests and diseases in agriculture. The insecticidal lamp is easy to operate, and the number of insect pests is wide and green. It has been widely used in the country. Insects that kill insects and insects will inevitably trap some beneficial insects, so how to avoid trapping insects by using insecticidal lamps?
Ignoring some tiny insects to analyze the types of insects that require insects in different fields is very difficult. Some species are small, the features are not significant, and classification is difficult; some tiny insects are scorched and unrecognizable when they touch the grid, and are artificially ignored. But these tiny species are often parasitic natural enemies of some pests. Therefore, there are certain limitations on the number of pests and pests.
There are certain limitations in the definition of pests
Now the analysis of the ecological effects of frequency-vibration insecticidal lamps has certain limitations in the definition of pests. For example, statistics on pests in a farmland often include pests of some trees or other plant pests. These species do not necessarily cause damage to farmland. Their existence may provide a certain food source and intermediate host for natural enemies in the farmland, which is conducive to the maintenance of natural enemy populations. It may also form a competitive relationship with some farmland pests in the niche. Conducive to the control of farmland pests. Obviously this part of the species should not be simply defined as a pest.
Problems ignored when evaluating control effects
The frequency-vibration insecticidal lamp plays a role in the adult pests and should be evaluated by adult control standards. That includes two aspects: the pest control effect of the same generation and the insect control effects of several generations in the future. For example, the use of frequency-vibration insecticidal lamps to control the American white moth, the anatomy of the adult worms found that some female adults have spawned or partially laid eggs, which means that this part of the adult has been breeding the next generation activities before being trapped. Therefore, it is also an important factor to evaluate the effect of prevention and control whether the adult being trapped has already laid eggs. Most of the evaluations now do not consider this issue.
In the fitness world, there are many definitions of peptide hormones, some of which are suggested to burn fat, build muscle, and improve athletic performance.
