HOUSE MOSQUITO

Common Name : House Mosquito.

Scientific Name : Culex pipiens.

Size : Light brown.

Description :
Culex pipiens is a light brown, medium sized mosquito with a blunt tipped abdomen (body). There are narrow white bands on the body segments but none on the legs or proboscis (beak or biting mouth parts). Males resemble the females, but are easily recognized by their bushy antennae.

Habitat :
Stagnant water, Polluted streams, catch basins, untended swimming pools and ornamental pools .

Lifecycle :
House Mosquitoes have four life stages: egg, larva, pupa, and adult. After an adult female lays her eggs they hatch into larvae (wrigglers) which feed on small organic particles and micro-organisms in the water. About four to six days are required for larval development. At the end of the larval stage, the mosquito molts and becomes the aquatic pupa (tumbler). The pupa is active only if disturbed, for this is the resting stage where the larval form is transformed into the adult. This takes about two days during which time feeding does not occur. When the transformation is completed, the new adult splits the pupal skin and emerges.

Disease Transmitted :
Wet Nile virus St Louis encephalitis .

Smokybrown Cockroach :
The smokybrown cockroach, Periplaneta fuliginosa, is usually found in decorative plantings and planter boxes, woodpiles, garages, and water meter boxes; it may occasionally inhabit municipal sewers. They sometimes invade homes, taking refuge in areas such as the attic. Nymphs are dark brown and have white segments at the end of their antennae and across their backs. Smokybrown cockroaches prefer the upper parts of buildings; they also may live under shingles or siding and sometimes get into trees, shrubs, and other vegetation during summer months. Females carry the dark brown to black egg case, which measures about 3/8 inch long, for about 1 day before dropping it; eggs can quickly hatch in 24 days or take 70 days after being laid, depending on temperature. About 40 to 45 nymphs hatch from a single egg case.

Symptoms :
Saint Louis Encephalitis:Fever, severe headache, nausea, and stiff neck.Severe cases may include vomiting, disorientation and paralysis.West Nile Virus Fever, headache, nausea, body aches and swollen lymph nodes.

Type of Damage :
They also transmit the organisms causing bird malaria, fowl pox, and heartworm of dogs.

Field Cockroach :
The field cockroach, Blattella vaga, prefers outdoor locations and is usually found in leaf litter and plant debris. Field roaches invade indoor areas when it is hot or dry outdoors and are often mistaken for German cockroaches. Field roaches are more olive in color than German roaches and they have a black stripe between the eyes. Adult females carry the egg cases until they are ready to hatch. Each egg capsule usually contains between 30 and 40 young. Development from a newly emerged nymph to adult can be completed in about 3 months.

Prevention :
Where possible, sources of standing, fouling water should be eliminated by dumping, filling, pumping, or draining.Temporary containers around the home, such as buckets, flower vases, tubs, and tires should be checkedUnderground drains or cleanouts should also be checked.
