Which insect is an example of a beneficial insect used as a biological control?
An example of beneficial insects used for pest control is the ladybug. Ladybugs are predators to aphids, which are small, sap-sucking insects that can damage plants and leaves.
What are three biological pest control methods?
Importation, augmentation and conservation of natural enemies constitute the three basic approaches to biological control of insects. Specific techniques within these approaches are constantly being developed and adapted to meet the changing needs of pest management.
What are the biological control practices for insect pest?
The main groups of insect disease-causing organisms are insect-parasitic bacteria, fungi, protozoa, viruses, and nematodes. Biological control using pathogens is often called microbial control. One very well-known microbial control agent that is available commercially is the bacterium Bacillus thuringiensis (Bt).

- Importation.
- Augmentation.
- Conservation.
- Predators.
- Parasitoids.

What are the example of biological control?
Examples of biological control include the destruction of the citrophilus mealybug in California by two parasitic species of chalcid wasps imported from Australia, Coccophagus gurneyi and Tetracnemus pretiosus; the effective predation of an Australian ladybird beetle, or vedalia beetle (Rodolia cardinalis), on the …
