•  Bacillus thuringiensis

  Bacillus thuringiensis (or Bt) is a Gram-positive, soil-dwelling bacterium, commonly used as a pesticide. Additionally, B. thuringiensis also occurs naturally in the gut of caterpillars of various types of moths and butterflies, as well as on the dark surface of plants.

•  Predation

  In ecology, predation describes a biological interaction where a predator (an organism that is hunting) feeds on its prey, (the organism that is attacked). Predators may or may not kill their prey prior to feeding on them, but the act of predation always results in the death of the prey, and is never to its benefit. The other main category of consumption is detritivory, the consumption of dead organic material.

•  Biological pest control

  Biological control of pests in agriculture is a method of controlling pests that relies on predation, parasitism, herbivory, or other natural mechanisms. It can be an important component of integrated pest management (IPM) programs. Biological Control is defined as the reduction or protection of pest populations by natural enemies and typically involves an active human role. Natural enemies of insect pests, also known as biological control agents, include predators, parasitoids, and pathogens.

•  Parasitoid

  A parasitoid is an organism that spends a significant portion of its life history attached to or within a single host organism which it ultimately kills (and often consumes) in the process. Thus they are similar to typical parasites except in the certain fate of the host. In a typical parasitic relationship, the parasite and host live side by side without lethal damage to the host. Typically, the parasite takes enough nutrients to thrive without preventing the host from reproducing.

•  Beetle bank

  In agriculture, a beetle bank is a strip of grass or perennial plants in a field that provide habitat which fosters and provides cover for insects hostile to pests, such as Chrysoperla carnea and ichneumon flies. Typically made up from sunflowers, Vicia faba, Centaurea cyanus, coriander, borage, and buckwheat, the banks are used as a form of biological pest control to reduce or replace the use of insecticides, and can also serve as habitat for birds and rodents.

•  Scoliidae

  Scoliidae, the scoliid wasps, is a small family represented by 6 genera and about 20 species in North America, but they occur worldwide, with a total of around 300 species. They tend to be black, often marked with yellow or orange, and their wing tips are distinctively corrugated. Males are more slender and elongate than females, with longer antennae, but the sexual dimorphism is not as extreme as is common in the Tiphiidae, a closely-related family.

•  Integrated pest management

  Integrated pest management (IPM) is an agricultural pest control strategy that utilizes a variety of complementary strategies including cultural management (growing practices), life cycle analysis, chemical management, among others. These methods are performed in three stages: prevention, observation, and intervention.

•  Beneficial insects

  Beneficial insects (sometimes called beneficial bugs) are any of a number of species of insects that perform valued services like pollination and pest control. The concept of beneficial is subjective and only arises in light of desired outcomes from a human perspective. In farming and agriculture, where the goal is to raise selected crops, insects that hinder the production process are classified as pests, while insects that assist production are considered beneficial.
