ANOPHELINAE & CULICINAE : LARVAE

The larva (larvae - plural) hidup dalam air, dia dok kat permukaan air sebab nak bernafas.. They shed their skin 4x growing larger after each molting. Most larvae have siphon tubes for breathing and hang from the water surface. The larva feed on micro-organisms and organic matter in the water. On the fourth molt the larva changes into a pupa.

Mosquito larvae, commonly called "wigglers" or "wrigglers", must live in water from 7 to 14 days depending on water temperature.

Larvae must come to the surface at frequent intervals to obtain oxygen through a breathing tube called a siphon. The larva eats algae and small organisms which live in the water.

During growth, the larva molts (sheds its skin) four times. The stages between molts are called instars. At the 4th instar, the larva reaches a length of almost 1/2 inch.

When the 4th instar larva molts it becomes a pupa.


cnie aq akan xplain basic je nak beza antara semua larva ni.. ade banyak lagi cara untuk bezakan, tapi aq gtaw yang utama je ek.. ps : note aq sume kat buddy so aq xley la nak xplain lebey2 sebab xingat sangat.. hehe.. sebab tu aq xplain basic je.. ;p


SUBFAMILI ANOPHELINAE
LARVA NYAMUK GENUS ANOPHELES
terang2 ley tengok larva ni xde siphon so they must lie parallel to the water surface in order to get a supply of oxygen through a breathing opening.

SUBFAMILI CULICINAE
LARVA NYAMUK GENUS AEDES
larva ni aq bezakan dengan tengok gills.. sebelah siphon.. aedes nye gills panjang ckit dp yang lain
LARVA NYAMUK GENUS CULEX
larva ni pulak, siphon dia paling panjang

LARVA NYAMUK GENUS MANSONIA
siphonnye adelah bergerigi, sebab kena cucuk kat akar kan
actually senang je nak beza, caranye tengok la lama2 mende alah ni.. i.allah masa exam skali tengok da taw menda ape.. tengok jugak pic2 yang lain kat tenet walaupun masa exam, pic ni je yang dyorg guna..
