General Pest Control(ODA Category 10A)

Areas covered by exam:

Pest Identification

Biology of Major Pest Groups

Control Approaches

Reading & Understanding Label Instructions

Groups Included in “General Pest”

Cockroaches Pantry Pests (grain & flour pests)

Nuisance Pests (ants, bees, wasps, flies)

Fiber & Paper Pests (carpet beetles, clothes moths, silverfish, booklice)

Structural (carpenter ants & bees - not termites)

Occasional Invaders (spiders, centipedes, millipedes, earwigs, mites, etc.)

Parasites (fleas, ticks, lice, bed bug)

Rodents

Characteristics of the PhylumArthropoda

The segmented bodies are arranged into regions, called tagmata (e.g., head, thorax, abdomen).

The paired appendages (e.g., legs, antennae) are jointed.

They posses a chitinous exoskeletion that must be shed during growth.

They have bilateral symmetry.

The nervous system is dorsal (belly) and the circulatory system is open and ventral (back).

Arthropod Groups (taxa)

The arthropods are divided into two large groups that exist today:

The Chelicerates

and

The Mandibulates

Chelicerate Arthropod Characters:

Pincher-like mouthparts - chelicerae - and pedipalps

NO antennae

Two body regions, usually - cephalothorax & abdomen

Four pairs of legs

Horseshoe crabs and arachnids are only living groups

Mandibulate Arthropod Characters:

Mouthparts are mandibles - normally chewing sideways

One or two pairs of antennae

Various body region arrangements - cephalothorax & abdomen / head & trunk / head, thorax & abdomen

Variable leg numbers

Insects, crustaceans & myriapods

Orders of Arachnids

Scorpionida - scorpions

Pseudoscorpionida - false scorpions

Phalangida - daddy-long-legs or harvestmen

cephalothorax & abdomen body arrangement, have gills)

Isopoda - sowbugs or pillbugs

Amphipoda - sand fleas, amphipods

Cirripedia - barnicles

several other minor orders

Crayfish cephalothorax(Decapoda)

Sowbug (Isopoda), a terrestrial crustacean

Class Insecta(all have one pair of antennae, a head, thorax &

abdominal regions, three pair of legs, adults usually have wings, use trachea)

Cockroach Species

German Brownbanded American Oriental (=waterbug)

Domestic Ohio Species

Native Species Woods roach

Cockroach SpeciesSpecies Size Life Span Preferred Habitats

American Large

1.3-2.1

1.5-2.0 yr Needs water, commonly breeds in sewer systems & underground utility systems.

Oriental Medium

1.0-1.3

1.0-3.0 yr Prefers high humidity areas, can withstand freezing temps, often in basements, garages, crawl spaces.

Brownbanded Small

0.5-0.6

90-280 days Can withstand dryer conditions, often lives in electrical equipment, attaches egg cases anywhere.

German Small

0.4-0.6

2-6 months Retains egg case until hatching, needs warmth, & water, often around food processing areas.

Cockroach SpeciesWoods Roach

Native North American species Attracted to lights at night Reduce dense outside vegitation Exclusion or parameter sprays useful in control

Cockroach Management

Monitor (sticky traps, flushing agents, determine extent of population)

Sanitation Exclusion (caulking, parameter sprays)

Reproductive Strategy (single or multiple queens)

Nuisance Ants

Common Ohio Ants

Carpenter Ant

Characterized by having polymorphic workers

Nest by excavating decaying wood or voids (they don’t eat the wood, they cast out wood shavings!)

Major nests in trees (satellite nests in buildings where water is available)

Most active at night (best time to find colony(ies) is at night!)

Carpenter Ant Management

Locate nesting site(s) (outside and/or inside - look at night, repair water damaged structures)

Prune back trees and shrubs touching infested building

Seal external entry sites

Exclude with parameter sprays

Treat colonies (injection, dusts) (baiting is rarely successful)

Ant Management

Identify species!

Locate nesting site (outside and/or inside)

Cat, dog & rat fleas are most commonly found (cat flea is, by far, the most common on dogs and cats!)

Adults suck blood for food
