Resting posture: Distinguishing characters of Anopheline & Culine larvaeAnopheline larvaCulicine larvaWhen undisturbed, larvae of Anophelines lie flat along the surface of waterIn contrast, in a similar situation, culicine larvae hang head down from the surface of water keeping the tip of breathing tube (siphon) in contact with the surface of water 17. Anopheles: Rests parellel, spiracles in 8th seg., presence of palmate hair 18. Culex: Hang downwards, siphon in the 8th seg. C like move, not sensitive to light, not gregarious, long siphon 19. Aedes: Downwards, short barrel shaped siphon, spiracle in the tip, S move, light sensitive, gregarious 20. Mansonia: Attached to roots of pistia, respirate through the root cells. 21. Visual recognition of Aedes & Culex larvae Aedes Gregarious in habit Air tube (siphon) short, about twice as long as wide Siphon with only one pair of ventral hair Move in a characteristic (S/8) fashion, involving all parts of the body React quickly to changes in light intensity, removal of the cover from the container will disturb them- dive to the bottom Culex Not gregarious in habit Siphon long & tapered, at least 3 times as long as wide With more than one pair of ventral hair Whip-like or figure C movement which propels them rapidly to the bottom of the container Not sensitive to changes of light intensity. A rather strong disturbance required to cause them go to the bottom- return fairly soon to the surface 22. ]} memw Lw ]qnbmnb em ]} Lntev IS ]} Ptem]cnXen InSv HtPmSn Fb S}_|I hgn izkn Ch enhbpw NetfmSv Ne {]XnIcnhbpamWv ]} `nn ]qnbmm hf ]qnbmm 2 Znhkw thWw ]}Iph em cq]mcw {]m]n sImXpImhp ImepI, NndI, IqI, hmbv`mK, Fnh cq]sSp. 23.

MaleAnopheline: Palpi enlarged at tip (club shaped)Culicine: Palpi distinctly longer & always papering at tip 30. FemaleAnopheline: Palpi = proboscisCulicine: Palpi < Proboscis 31. Proboscis of aedes: Slim, straight, decorated 32. Anopheles: Spotted, Clumping of dark 7 light coloured scales 33. Culex: Non spotted with narrow scales on veins, clear wings 34. Aedes: Light scales with brown/black in colour 35. Mansonia: Broader scales asymmetrically arranged, speckled wings 36. Rest Anopheles: creates an Culex: Parellel to surfaceangle in resting, Dark pale colordull coloured often brown Aedes: Hunched back, dusty appearance , grey color Mansonia: Hunched back, brown color 37. Anopheles:Adult Aedes:Adult Culex:Adult Mansonia:Adult 38. Breeding habits Anopheles: Fresh Culex: Water with water, water tanks Aedes: Artificial containers like coconut shells, tyres, tubes, broken pots,,,bio-waste contents Mansonia: Ponds, lakes etc., Pistia. 39. Blood meals Anopheles: Both Culex:Preferablyantropophilic and zoophilicanthropophilic, Aedes: Anthropophilic and zoonophilic Mansonia: Anthropophilic 40. DISTINCTION AEDES ALBOPICTUSAEDES EGYPTI Not a house hunting mosquito Vigourous biter Natural enemy: toxorynchitinae 1/100 worlds most invasive species. Can see 2 white lines in the misonotum House hunting mosquito Can bite through socks and shirts Vicious (violent) biter Only 1 white line in the misonotum and divides when reaches scutellam. 41. sh Un 42. sh Un Fm sImXp nb{W {]hfpsS Bkq{XWntm, hnebnentm thn sImXpIfpsS kmn[ysdntm, km{Xsbdntm D imkv{Xobamb hnhc tiJcWamWv sh Un 43. sh UnbpsS ey P sImXp Py tcmKsfdnpw sImXp nb{W {]h {]hfpsS BhiyIXsbdnpap hnhc tiJcWn tiJcWnv ap sImXp km{XbptSbpw ap Ime tcmK Ncn{Xsbpw ASnm ASnmamn A]ISkm[yXm {]tZi dnbm Xncndnbm sImXpP sImXpPy tcmKfpsS s]mnpdsS apqn Adnv kzoIcnm {]Xntcm[ S]SnI kzoIcnm ZoL Ime {lkz Ime sImXp nb{W X{ BhnjIcnm BhnjIcnm {]h tcmKImnb{W {]hfpsS ^e{]m]vXn AfXn AfXnv 44. sh Unbn Fsmw hnhcfmWv thXv? sImXphn`mKfpsS km{Xbpw hnXcWhpw c]mntbpw hn{iantbpw hnhc {]X|]mZ kz`mh sImXpminn {]tbmKns km[yX tcmtKm`hns t{kmXv 45. sh Un St kqNnIm {]tZi GsXmamWv?sImXp Py tcmKw FUanmb e sImXpIns kmn[yw sImpw ]mcnnXnI {]tXyIXI sImpw tcmK]Im km[yXbp e tcmKns s]mnpdsSepmb ew 46.
