Venation Pattern Of Mosquito Wing

In the archetype pattern A the media forks into two main branches. Recent work on miniature winged robots has used natural veined insect wings as models for biomimetic wings 59 60.

The archedictyon is the name given to a hypothetical scheme of wing venation proposed for the very first winged insect.

Venation pattern of mosquito wing. WING VENATION PATTERN OF PLECOPTERA INSECTA. In this study the wing venation and its variation in A. They are easily distinguished from most other flies by a combination of the following characteristics.

Assamensis were analysed using traditional as well as landmark-based morphometric methods. The fifth vein of the wing is the media. This is unlikely compared with the situation in other insects where only one pattern exists per order.

BDepartment of Molecular Genetics and Cell Biology University of Chicago Chicago IL 60637. This study focused on the 59 specimens of mosquitoes collected from Pulilan Bulacan Quezon City Navotas Metro Manila Makati Metro Manila and Antipolo Rizal. The main longitudinal veins transmit fluid oxygen or sensory information while the cross veins are rarely fluid-filled and serve various structural roles.

CApplied Physics and Applied. Rycroftae2 aPaulson School of Engineering and Applied Sciences Harvard University Cambridge MA 02138. Hence the interpretation of.

The wing surface is not flat but corrugated like a Japanese fan with alternating ridges and depressions. An approach to automatic hoverfly species discrimination based on detection and extraction of vein junctions in wing venation patterns of insects is presented in the paper. A fringe of scales along the posterior margin of the wing.

Within the phylogeny of insects examples of adaptive wing shapes and modified wing structures eg elytra and halteres abound. Methods are described for the automatic measurement of morphological features of mosquito wings wing outline and venation from TV images of specimens mounted on microscope slides. A simple developmental model recapitulates complex insect wing venation patterns Jordan Hoffmanna1 Seth Donougheb12 Kathy Lic Mary K.

Though wing venation is one criterion in identifying the genera of mosquitoes it cannot solely be used. Since all winged insects are believed to have evolved from a common ancestor the archediction represents the template that has been modified and streamlined by natural selection for 200 million. The present study by illuminating principles of geometric wing design could guide efforts to generate life-like synthetic vein patterns and in turn be used to examine how vein patterns affect the mechanical properties of a wing.

Antheraea assamensis Helfer 1837 is a sericigenous insect with distinct coloration namely green blue orange and yellow in their larval stages and these are multivoltine in culture. The presence of scales on the wing veins. And a characteristic wing venation the second fourth and fifth.

NEOPTERA Olivier Béthoux Department of Geology and Geophysics Yale University PO. A long proboscis projecting forwards from the head. Mosquitoes are small up to 15 mm two-winged insects.

The patterns that these veins create are called venation patterns. The mechanism of wing vein differentiation in Drosophila is a classic text-book example of pattern formation using a system of positional information yet very little is known about how species with a different number of veins pattern their wings and how insect venation patterns evolved. Note that the veins and morg of the wings are covered by scales which sometimes form characteristic patterns.

Two different patterns of wing venation are currently supposed to be present in each of the three orders of Paraneoptera. 3 – Wings – venation scales 4 – Wing scales – scanning electron microscope images 5 – Hearing organs flight thermoregulation Wings A female Brimstone Gonepteryx rhamni seen here extending its proboscis to suck up nectar from a thistle flower. Obethouxyahoofr ABSTRACT Some consider the order Plecoptera as the sister-group of all neopterous insects.

The convex and concave veins are often marked and – respectively eg. Study the venation and nomenclature of the mosquito wing in the material given. It is based on a combination of speculation and fossil data.

On the ridges there are convex veins C R1 MA CuA 1A and in the depressions there are concave veins Sc Rs MP CuP. The biomechanical effects of venation patterns can be assessed from another perspective as well. The digitized images were preprocessed to locate the ridge points in the gray-scale image surface and the digitized images were thinned so that veins could be.

In one genus the second or subcostal wing vein has a row of bristles near its base on the ventral side. Wing shape venation pattern and flight behavior are influenced by many selective pressures including ecological niche predator avoidance and behavior to name a few. Zool 343346-358 1985 automatic description of the venation of mosquito wings from digitized images yuan-hua zhou1 long-bin ling2 and f.

Venation Insect wings are composed of tubular supporting veins through the deformable membrane. Salcedod and Chris H. Although morphological analysis of characters is the gold standard for mosquito identification geometric morphometrics based on quantitative analysis of mosquito wing venation characters has proved to be a reliable tool in mosquito identification as well showing a high identification power when distinguishing morphologically similar species.

A media anterior MA which divides into two distal branches MA1 MA2 and a median sector or media posterior MP which has four terminal branches M1 M2 M3 M4. We propose for all Paraneoptera a new and unique interpretation of wing venation pattern assuming that the convex. However wild morphs with diapause are found in dense forests.

Box 208109 New Haven CT 06520-8109 USA E-mail. The longitudinal and cross-veins have specific names.
