pest control management: roaches, rodents and flies
TRANSCRIPT
INTEGRATED PEST MANAGEMENT
A Total Quality Pest Management A Total Quality Pest Management PresentationPresentation
Reasons for the development of resistance:
• Use of only one class of insecticide• Inadequate planning or a poorly conceived control operation• Overextension of product features (target dose reduction)• Neglect of resistance management procedures
Rotation of ChemicalsShift from one chemical grouping to another
CHEMICAL GROUPINGS:Organochlorine very persistent
OrganophosphateCarbamateSynthetic Pyrethroid very low toxicity
Insect Growth RegulatorsPhenylpyrazolesChloronicotinyl
Sanitation
• Sanitation – promotion of hygiene and prevention of disease by the maintenance of sanitary conditions
- should be under the supervision of Quality Assurance Manager - in coordination with plant managers and full support
of all top management
Factors Making Pest Management Difficult
√ Raw food items and packaging materials entering a plant may serve as a source of pests
√ Various food odors attract insects to food plants√ Exterior lighting attracts insects to food plants√ Warm buildings and moist processing areas favor pests√ Machinery, wall voids, conduits, and conveyors provide ample pest
harborages

years.

RODENTSRODENTS
Most successful mammal, second to humans.
Commensal Rodents“sharing one’s table”
“to gnaw”
Baits will also be placed in rat harborage such as burrows and ground voids.
To inspect the bait placements on a regular basis and replenish when it runs out.
The period between inspections would depend on rodent population, bait acceptance and environmental conditions that may accelerate bait spoilage.
Baits are placed to ensure that the rodent is intercepted between its harborage and food sources.
Rodent Management
BaitingBaiting
Rats are nocturnal, with their peak activity half an hour after sunset and half an hour before sunrise.
When the population is large or they are disturbed or hungry, you can see activity during the day.
Rats are suspicious of changes in the environment or new foods, for this reason it may take a couple of days for traps and poison baits to be taken.

(with over 1,000,000 species)
Flies Management
FACTS ABOUT FLIES• Flies transmit deadly diseases such as:
• Typhoid fever - Diarrhea - Cholera• Leprosy - Dysentery - Tuberculosis
• Each fly may carry as many as 6 million bacteria on it’s feet
• When feeding, flies expels saliva and feces
• A female fly will lay anywhere up to 3,000 eggs in their lifetime

Mosquito Management
3 Main Species of Mosquitoes
The average lifespan of an Aedes mosquito in Nature is 2 weeksThe mosquito can lay eggs about 3 times in its lifetime, and about 100 eggs are produced each time. The eggs can lie dormant in dry conditions for up to about 9 months, after which they can hatch if exposed to favourable conditions, i.e. water and food
