Which of the following is an example of a beneficial insect that preys on harmful insects?

1. Lace Bugs

2. Mealybugs

3. Ladybeetle

4. Spider Mites

The correct answer is: Ladybeetle

The identification of the ladybeetle as a beneficial insect that preys on harmful insects is well-founded. Ladybeetles, commonly known as ladybugs, are voracious consumers of aphids, mealybugs, and other pests that can harm plants. By controlling these populations, ladybeetles contribute to the overall health of gardens and agricultural practices, making them an important part of integrated pest management. In agricultural settings and landscaping, the presence of ladybeetles can significantly reduce the reliance on chemical pesticides, promoting a more environmentally friendly approach to pest control. Their life cycle and reproductive habits allow them to establish populations that can sustain the pressure on harmful insect populations, ensuring a balance in the ecosystem. This role as natural predators highlights the importance of preserving beneficial insect species within any pest management strategy.
