Preventing Damage by Termites or White Ants 5 THE HEPEODTJCTIVE FORMS Owing to the increasing number of eggs that develop within her, the queen becomes enlarged, but never loses the power of locomotion. It was once believed that, since the queen mother was the source of the colony life, the termite colony would be exterminated if she were destroA'ed, but this has been disproved by more recent studies. In addition to the forms that have shed their wings, several different tvpes of reproductive forms occur—forms with wing pads (the un- developed wings of the nymphs) and wingless reproductive adults. The winged forms, however, are the normal type and occur as a single pair, whereas there may be hundreds of the other forms head- ing colonies. The reproductive forms with wing pads and the wholly wingless type usually have little color to the body, and the eyes are small. These forms rarely come above ground or leave the burrows in Fig. 4.—Quartpi-ed-onk flooring damaged by the suliterranean termite_ iee^cMii- tcrincs fluripes in an infested Iniilding-, Wasliington, D. C, IJlo The location of the queens in the colony depends upon the seas(m of the year. During periods of intense heat or drought in the plams or in arid or prairie regions the subterranean termites burrow deeply below ground or to a less depth under stones, cow chips, etc. During winter in the colder climates they burrow below the frost line. Whole colonies of subterranean termites migrate when conditions become unfavorable. The nonsubterranean termites, on the other hand, are not able to leave the wood in which they have excavated their Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Craighead, Frank C.
