Show FIGHT HUNGRY BUGS BY POISON SPRAYS fortunately for the aspras sprats and other menns means of fl fighting litiuz insects are discovered almost as aa fast as new pests make themselves a nul but sance so we are never in any immediate danger of losing our fight against the hungry invaders T the be ways la in which these remedies have been di discovered S are very Interest interesting ind a and ad while same some of them may seem q quite e simple uit to us now they required red m many ny hours of study and work b before e fore they were perfected before a poison that was loth both cheap and effect effective lye could be found it was wag necessary for someone to study each kind of bug to learn ju just st how it obtained its food when it eats etc As lou all know many kinds of our insect pests pass through at least three stages in their life cycle starting RS aa a tiny egg they hatch out as worms which eat greedily for awhile and then go into a resting stage when we call them pupa or larva from the resting stage they come as gaudy butterflies or drab colored moths in this portion of their existence they eat very little except poa possibly a little nectar from floii flowers ers it Is evident then that if we hope to poison such an enemy we must do so when it Is 1 a worm and greedily eating the green leaves oft off our flowers and vegetables numerous poisons chief of which are forms of arsenic ar are used there ethere are however many forms of bugs which do not eat green leaves but get their food by inserting their bills into leaves and stems and then sucking the juice stomach poisons are of not use nse in fighting such ouch bugs as those now the many forms of bugs all have breathing apparatus that Is similar it consists of a number of openings along the side of the body from these openings tiny tubes lead to all parts of the insects body As the insect moves about air Is drawn in the openings and valves immediately close behind it further movements of the insect then force the air through the tubes to the various tissues where it Is needed it if the opening should become closed or the breathing apparatus be put out of order the insects would die for want of air just as you would it your mouth and nose should be closed tightly here then Is a good place to attack such pests kerosene emulsion oil emulsion miscible oils soap solutions and the like are used against these sucking insects certain contact sprays have been developed which enter the breathing pores of insects but depend for their action on poisoning the bug rather than on smothering it it we would suffer much the same way were we to breathe the fumes from certain chemicals before attempting to destroy pests that damage our gardens and fruit we must then study them carefully to determine just how they should be treated it Is a mistake and a waste of time to just throw on something in the hopes that it may do some good the worst pest may be controlled it if it it handled rightly A point to kemem her ber Is that to control any particular insect very c careful spraying be done |
