Insects and Vermin Control: Strategies and Life Cycles

insects

six-legged, air-breathing invertebrates with a segmented body, including a head, thorax, abdomen, two antennae, three pairs of legs, and usually two sets of wings.

examples of insect species.

Bees, flies, crickets, beetles, and gnats.

vermin

A group of insects or small animals that are vectors of diseases, such as flies, mosquitoes, cockroaches, lice, bedbugs, mice, and rats.

vectors

are arthropods or other invertebrates that transmit infections by inoculation or through skin/mucous membranes by biting or depositing infective materials.

two ways diseases are transmitted by vectors

Mechanically, where the organism is carried on the insect's body without affecting it, and biologically, where the insect's body is essential for the organism's development.

List the basic methods for controlling insects and rodents.

Physical and mechanical, chemical, biological, environmental, and health education campaigns.

chemical methods control insect populations

rapid and effective but face constraints like behavioral resistance and insecticide persistence.

biological

It considers limiting factors that affect the growth and reproduction of pests.

environmental

To remove breeding places and attractants for pests.

health education campaigns

To motivate people to change habits and practices that promote the survival and multiplication of pests.

(musca domestica)

housefly

What are the primary breeding places for houseflies?

Human excreta, fresh horse manure, manure of other animals, and garbage.

What are some methods of controlling houseflies through environmental control?

Eliminating food sources and breeding places, proper refuse storage, food storage, and excreta disposal.

biological control work for houseflies

By releasing sterile flies that compete with wild males, reducing the population of offspring.

residual spray

for long lasting control. When applied, the

chlorinated hydrocarbons and organic phosphorous

insecticide will leave a film of crystals that will kill

space spraying

ultra low volume and thermal fog application - economical and fast. Putting a very fine mist or

aerosol into areas where flies are abundant, for killing a

large number of adults. To control fly quickly from

distance away.

larvicidal treatment

for control of maggots. It is directed towards the elimination of breeding media of larval habitats.

(blattela germanica)

cockroach

Up to 3 weeks.

How long can adult cockroaches survive without food?

What are the stages of the cockroach life cycle?

Egg case, nymph,nymph, and adult.

About 30-40 eggs.

How many eggs does a female cockroach lay in an egg case?

2 to 3 months.

What is the duration for a cockroach's life cycle from egg to adult?

What are some habits of cockroaches?

Active at night, hide during the day, fit into narrow spaces, live in groups, and prefer starchy materials.

Culex pipiens quinquefasciatus.

Aedes Aegypti

mosquito

About 100 to 300 eggs.

How many eggs does a female mosquito lay?

10 to 12 days.

What is the lifespan of an adult mosquito?

What is one method for controlling mosquitoes?

Environmental control, such as source elimination.

What are the distinguishing features of Norway rats?

Largest domestic rats, burrowing animals, and have a life span of about one year.

What is the average gestation period for rats?

22 days.

Mus musculus.

What is the scientific name of the house mouse?

Rattus rattus

Roof rat
