3rd EXAM Flashcards
- All forms of legislations and regulation preventing entry, establishment
and spread of a pest organism - Control of pest organism through legal or regulatory actions
Regulatory Control (Legislative/Legal)
specific technique to reduce the population or the
effect or damage of the pest on the crop. Conventionally, they are
grouped based on the form of the control agent or the manner by
which the agent of control is used.
pest control methods or pest control tactics
specific technique to reduce the population or the
effect or damage of the pest on the crop. Conventionally, they are
grouped based on the form of the control agent or the manner by
which the agent of control is used.
pest control methods or pest control tactics
pest present in the area
Regulated non-quarantine pests
Type of Quarantine Laws
- International Quarantine
* FAO-IPPC on SPS Agreement - Domestic Quarantine Laws
a. Congress
b. Department of Agriculture
c. Local Government Issuance
3 stages of PRA
Stage 1 – Initiation
Stage 2 – Pest categorization & risk assessment
Stage 3 – Risk management
Regulatory Control of Non-Quarantine Pests
Eradication Program, Containment Program, Suppression Program
Refers to the control of plant pests by living organisms under natural or artificial circumstances
Biological Control (Biocon)
is the sum of all mortality factors (biotic and abiotic) without intervention of man
Natural control
is the deliberate manipulation (conservation included) of natural enemies to control pests
Biological control
naturally-occurring population
Natural enemy
mass-produced population and released to the environment
Biocon agent
- Involves tactics that cause the pest to contribute to the destruction of its
own population - Ingenious, highly publicized technique
Autocidal Control
Decreasing the ecological fitness of a pest species by introducing
lethal genes in the population
Genetic Control
reduction of pest population
- Chemical attractants
- Repellents
Behavioral Control
Chemicals that cause insects to make oriented movement away from its source
Repellents
Ability of the plant to withstand or overcome the attack of pests resulting to lesser damage or effects on yield (quantity and quality)
Host Plant Resistance (HPR)
Deters pest before colonization
Antixenosis
-Toxic metabolites, absence or imbalance of essential nutrients
- Inhibitory enzymes
Antibiosis
-Toxic metabolites, absence or imbalance of essential nutrients
- Inhibitory enzymes
Antibiosis
-Toxic metabolites, absence or imbalance of essential nutrients
- Inhibitory enzymes
Antibiosis
-Toxic metabolites, absence or imbalance of essential nutrients
- Inhibitory enzymes
Antibiosis
- Pest develops and causes injury but with little to no damage in yield
- Ability to grow and produce high yield even at higher insect infestations
- Damage is compensated by increasing growth (e.g. more tillers, bigger fruits, etc.)
Tolerance
- Refers to plant immunity to pathogens
- “Total resistance”
- Applicable to plant pathogens
- Pathogen cannot cause disease even under favorable conditions for the development of the pathogen
Immunity
