[Biology Class Notes] on Flea Life Cycle Pdf for EXAM

Fleas are holometabolous, blood-sucking parasites that assume the job of transporters for different illnesses. Parasites are organisms that depend on different organisms called hosts for supplements. Not at all like different insects, for example, dragonflies, honeybees and grasshoppers, fleas experience complete metamorphosis. This implies the organism experiences through four unmistakable stages before turning into an adult. Fleas are a bane for animal proprietors just as most other warm-blooded animals with hair or fur. With regards to wiping out fleas from your pet and from your home, there are some key interesting points. To begin with, it is imperative to be acquainted with and comprehend the flea life cycle when you are attempting to eradicate their quality completely. In this article, we will learn about the flea cycle and the stages of the life cycle of the flea in detail.

Complete Metamorphosis

A normal flea has no wings however a hard exterior. Its absolute body length ranges between 0.1 cm to 1 cm. Flea’s essential source of food is blood, as a rule from mammals. A flea invasion can cause extreme inflammation of the skin just as skin bothering. A few fleas are additionally vectors of numerous maladies. The types of fleas that have human hosts are known as Pulex irritans, likewise called ‘human fleas’.

There are four different stages in the life cycle of a flea which are egg, larva, pupa, and adult. Depending on the natural temperature and mugginess levels, the entire life cycle will take anywhere from two or three weeks to numerous months.

Life Cycle of Flea

()

1. Stage 1: The Egg

The male and female fleas lean toward a warm and damp condition for mating. In the wake of mating, small pearl-like eggs are laid on the outside of the host. These eggs endure on the garbage of the host, for example, portions of dry skin, dried faecal matter, and dried blood. A female flea lays around 50 eggs. In good conditions, the eggs incubate in around 12 to 14 days.

2. Stage 2: The Larvae

The larvae rise out of the egg without eyes, legs and take cover on mammals or the closest rug strands it can discover. The flea larvae are not quite the same as adult larvae as it doesn’t feed on blood however devour sizes of dry skin, dried flotsam and jetsam, food particles, and dead insects. If not vacuumed from the rug or cleaned from the splits of the floor, flea larvae can make due as long as 18 days. Toward the finish of this stage, the larvae spin silk cases and enter the pupa stage. Larvae join earth and different trash so as to disguise and secure at that point till they change into the pupa stage.

3. Stage 3: The Pupa

Since the flea larvae have not built up any physical pieces of their structure, in the pupa stage, the flea builds up all organs in sticky conditions. In the event that nature is damp and ideal, at that point, the adult flea develops in seven days. In the event that the conditions are not good, at that point pupa can take a year to turn into an adult flea.

4. Stage 4:The Adult

The adult flea feeds on the blood of the host and leaves blood flotsam and jetsam that shows up as black particles on the exterior of the host. These black particles are obviously perceptible on the fur of dogs and cats who have fleas. The following thing an adult flea does is hunt for a host to live, lay eggs and feed blood.
