(1) The body of an insect is protected by a horny exoskeleton. This horny exo-skeleton consists largely of a substance called chitin. (11) The whole body of an insect is obviously Semented, and do clearly divisible into three Kamka. These are the head, khora, and abdomen. (isi) at each side of tile head of an insect is large ecapound eye which is composed of fow hundreds of simple eyes. Close to mach eye. there is an antenna, The mouth parts are specially adapted for either chewing, sucking or lapping. (1) The thorax consists of three segments only. These are brothorax, mesothorax and metsthorax. Each segment besre e rait of jointed legs on the ventral side, and one pair or two pairs of wings on the dorsal surface,

(vi) The spiracles are located along the sides of the thorax and abdesen. The trackeas leading fron the spiracles form many branches in the inte, nal tissues of the body. The two examples of pestiferous insecta ara:
(A) House-fly - The habit of the fly of visiting
indiscriminately human food and organië refuse is to some extent responsible for the spreading of diseases. Dysentery is perhaps the commprest disease caused by flies, but others are diphtheria, typhoid and anthrax. Hethods of control:
(1) Do not leave refuse about so that fliss
can lay their eggs on it.
(11) Cover food (especially meat and milk) as much as possible to prevent flies landin
it and excrating on it..

(iv). Use insecticides, sticky papers and
deterrents.
(v) Keep dustbins dry.
Mosquito: Tropical mosquitoes (Anopheles). are the carriers of malaria, yellow fever, elephantiasis and dengue fever, all of whion affect man and in many cases can be fatal. Methods of controlin
(1) Spraying standing water and swamps with
insecticides to kill the larvas
11) Spraying buildings, caves etc. to kili

larvae, to the water tzra the: larvas nr.med.

(b) Insects may be either useful or harmful. The
butterflies are important in pollination of th flowering plants, but a great damage can be caused to crops by the larvae of the cabbage white butterflies and often complete defoliation will result from a severe attack. Many insects act as scavengera, destroying and burying dead animals and plants, all-flies modify plant tissues into substances which can be used for industries such as tanning, dyeing and ink manufacture. Silk-worms provide silk
Many animals which are used as human food) feed themselves on insects. Insects therefore occupy a place in human food-chains
Injurious insects are mainly of unree types i [the housefly, mosquito etc. which cause th
diseases of man; the crane-flies and green-fly- ete. which damage crops; and those which damage for destroy useful commodities such as clothes and furnitures. Examples are the clothes-moth larva, termites and death-watch bestles.
(a) Giye brief reasons for classifying a liabbage White Butterfly as (1) an invertebrate.. (11) an arthropod, and (111) an insect. (b) with the help of diagrams, give an account of
the life-history of a Cabbage White butterfly.
41) The Cabbage white butterfly is classified as
[an invertebrate because it resembles to all
invertebrates that possess no back bonB „
(11) The Cabbage White Butterfly also belongs the
group of the arthropods, for it has jointed appendages and possesses a chitinuus exis skeleton which encloses a segmented body.
(iii) The Sabbage White Butterfly is again
classified as an insect, for it possesses all
the characteristic features which are commonly found in insects.

The Life-history of a Cabbage White Butterfly
The famle butterfly lays clusters of cream-
coloured eggs on the uriersides of the leaves of cabbages. A green caterpillar emerges from the egg. The caterpillar is the larva of the insect
It is long and slender, with a segmented body,..
The head has biting jaws, and the first three segments behind it carry three pairs of jointed legs. Four segments of the abdomen have projections which are called pro-legs. On the front of the head is a silk producing gland called á spinnērst,
The larva eats its egg-case at first, and then turns its attention to the leaves of the cabbage. It feeds greedily for some time and then finds a sheltered spot and spine a silken pad with silk which it squirts through its spinneret, Attaching the pad to a firm support, it grips it with claspers and spins round itself a silken
ling, hanging head-downwards,
After a couple of days the larval skin splits, rolls up and falle off, leaving the pupa posed. This has at first a transparent skin, through which all the features of the future butterfly can be recognized; but the skin is quickly covered with a fluid which hardens and darkens in colour. In this condition the pupa rests while internal changes occur. At the end of the resting period the pupal case splits dow the middle, and a perfect adult butterfly, the Imago; emergez
