Study Notes
Biological Control
- Slow acting is not an advantage of biological control.
- Ants, lacewings, and aphid lions belong to the order Neuroptera.
- The Anoplura order does not have beneficial species.
- A parasite that transmits a disease-causing organism to a plant is called a vector.
- A biological control agent that consumes many prey in its lifetime is a predator.
Control Methods
- Adhesive substances are used in physical control against insect pests.
- Early harvest is a cultural control method against pests.
- Water management can be used in all control methods except chemical control.
- Microbial insecticides are considered a biological control method.
Chemical Control
- The active ingredient in a product is responsible for targeting organisms.
- Pheromones are chemical substances produced by one organism to influence the behavior of others of the same species.
Pests and Beneficial Organisms
- An insect that annoys, injures, or damages humans is called an insect pest.
- Rodolia cardinalis is a predatory insect used to suppress the cottony cushion scale.
- Antibiosis is a mechanism of plant resistance that causes malformations and potential death of immature insects.
- Ephemeroptera is the insect order derived from a Latin word meaning "lasting a day".
- Tetrasticus is a parasitic wasp that parasitizes the pupal stage of Brontispa longissima.
- Icerya purchasi is a factitious host used in rearing predatory beetles on squash.
- Ladybugs belong to the order Coleoptera.
- A parasitoid is a biological control organism that lives inside its host and consumes only one host.
Integrated Pest Management (IPM)
- IPM aims to minimize damage by pests with the goal of permanent control.
- Chemical control is the least favored method in IPM.
- Regulatory control methods are closely related to quarantine control.
- Inoculative applications release biological control agents (BCAs) occasionally.
Biological Control Agents
- Predatory insects, pathogens, and parasitoids are all effective at managing insect pest populations.
- Predators have received the most attention in biological control because they are easy to handle and identify.
- Actinomycetes are not entomopathogens.
General Concepts
- Pest management is essential for maximizing crop yield, but not the sole factor determining yield.
- IPM combines various control methods harmoniously for effective pest management with minimal negative impact.
- Class Insecta is also known as Class Hexapoda, meaning "six-legged."
- Physical control methods involve setting barriers to prevent insect and rodent damage.
Pest Control Strategies Examples
- Cultural Control: Incorporation of soil solarization, planting of resistant varieties, early harvest, mulching, proper cultivation/tillage, proper irrigation/drainage, systematic planting.
- Biological Control: Release of earwigs against corn borer, seed bacterization, herding ducks to manage golden kuhol, grazing goats to manage weeds, integrating ruminants as lawn mowers.
- Chemical Control: Application of pre-emergence herbicide, fumigation of warehouses, application of protectants to manage disease, vapor heat treatment.
- Physical Control: Cold storage of fruits and vegetables, drying of seeds, baiting rats, light trapping, knockdown of pests with water, removal of breeding and hibernating places.
- Regulatory Control: Frost sentry, quarantine, inspection and certification of plants, prohibition and embargo.
Organism Identification
- Insect Pests: Scotinophara coarctata, Oryctes rhinoceros, Ostrinia furnacalis, Nephotettix virescens.
- Beneficial Insects: Trichogramma evanescens, Telenomus triptus, Tetrastichus brontispae, Diadegma semiclausum.
- Beneficial Microorganisms: Beauveria bassiana, Paecilomyces lilacinus, Bacillus thuringiensis, Metarhizium anisopliae.
- Pathogens: Peronosclerospora philippinensis, Fusarium oxysporum f.sp cubense Tropical Race 4, Rice Tungro Virus, Phytophthora palmivora.
- Weeds: Cyperus rotundus, Imperata cylindrica, Echinochloa crusgalli, Rottboellia cochinchinensis.
