Question

Каковы меры ,снижающие численность вредных насекомых

Answer 1

С вредными насекомыми иногда борются и химическими способами. Так, для уничтожения вредителей растений их обрабатывают ядохимикатами. Выгребные ямы и другие места размножения личинок комнатных мух обрабатывают хлорной известью. Тараканов уничтожают различными ядами. Однако у насекомых-вредителей довольно быстро появляются особи, приобретшие нечувствительность к ядовитому веществу. Кроме того, из-за применения ядохимикатов гибнут многие полезные насекомые, а также птицы, съевшие отравленных насекомых.

Answer 2

Самое эффективное без химии, кормушки и поилки для птиц. А уж они позаботятся. Только не перекармливать.

Answer 3

Measures to Reduce the Population of Harmful Insects

There are several measures that can be taken to reduce the population of harmful insects. These measures include:

1. Biological Control: Biological control involves the use of natural enemies, such as predators, parasites, or pathogens, to control the population of harmful insects. This method is environmentally friendly and can be effective in reducing pest populations.

2. Chemical Control: Chemical control involves the use of pesticides to kill or repel harmful insects. Pesticides can be applied directly to the insects or to the plants they infest. However, it is important to use pesticides responsibly and follow safety guidelines to minimize their impact on the environment and non-target organisms.

3. Cultural Control: Cultural control involves modifying the environment or cultural practices to reduce the population of harmful insects. This can include practices such as crop rotation, planting resistant varieties, and maintaining proper sanitation to remove breeding sites.

4. Physical Control: Physical control methods involve the use of physical barriers or traps to prevent or capture harmful insects. Examples include using nets, screens, or row covers to protect plants from insect damage, or using sticky traps to capture flying insects.

5. Integrated Pest Management (IPM): Integrated Pest Management is an approach that combines multiple control methods to manage pest populations effectively while minimizing the use of pesticides. IPM involves monitoring pest populations, setting action thresholds, and using a combination of biological, cultural, and chemical control methods as needed.

6. Genetic Control: Genetic control involves the use of genetically modified organisms (GMOs) to control the population of harmful insects. This can include the use of genetically modified crops that produce toxins harmful to specific pests or the release of genetically modified insects that carry genes that make them less able to reproduce or transmit diseases.

7. Education and Awareness: Educating farmers, gardeners, and the general public about the identification, prevention, and control of harmful insects can help reduce their population. This includes promoting practices such as proper sanitation, early detection, and the use of integrated pest management strategies.

8. Regulatory Measures: Governments and regulatory bodies can implement measures to control the population of harmful insects. These measures can include the registration and regulation of pesticides, quarantine measures to prevent the introduction and spread of invasive pests, and the establishment of monitoring and surveillance programs.

It is important to note that the effectiveness of these measures can vary depending on the specific insect species, the environment, and other factors. Therefore, a combination of different control methods is often necessary to achieve the best results.
