CIRCULAR. 5 



4(/. The prevailing direction of the wind from July till frost. 

 4/f. The sid^ of a field on which the worms first begin to work. 

 4i. Do local topographical features influence the extent of the worm's ravages f 

 4j. Does or can the worm feed upon any other plant than cotton, and have you ever 

 known it to do so ? 



HABITS AND NATURAL HISTORY. 



These have already been studied, and are pretty well known ; but experience will 

 differ somewhat with locality, and we call attention to the following topics: 



5. State the time when the first moths are noticed in your locality. 

 5a. Date when the first worms have been noticed in past years. 



56.' Date when the last worms have been seen in past years, or were noticed the 

 present year. 



DC. Number of broods or generations of the worms generally produced. 



M. In what other situations besides the folded cotl on leaves have you known the 

 worms to spin f 



5e. Have you ever known the chrysalis to survive a frost, or to be found in sound 

 and healthy condition in winter ? 



5f Have you ever found the moth hibernating or flying during mild winter weather f 



5<jr. How late in the spring has the moth been found alive ? 



NATURAL ENEMIES. 



It is a little singular that no enemies of the cotton- worm have hitherto been re- 

 ported. That the insect has its enemies, both special and general, there can be little 

 doubt, and we would ask particular attention to the following topics : 



6. Are any birds, quadrupeds, or reptiles known to attack the insect in your locality ? 

 6a. Are any predaceous insects or parasites known to prey upon it, either in the egg, 



larva, or clirysalis state ? 



REMEDIES AND METHODS OF DESTRUCTION. 



7. What has beerf the result of the efforts to allure and destroy the moths, and w hat 

 methods have proved most satisfactory ? Give your estimate of the relative value for 

 this purpose of poisoned sugar, molasses and vinegar, and fires. 



la. Are the moths most attracted to sweetened substances when smeared onto trees, 

 boards, etc., or when contained in vessels in or near \vhich lamps may be lighted? 



7b. Are any flowers known to be attractive to the moth ? If so, specify them and 

 thoir season of blooming. 



7c. What do you know of your own observation of the influence of jute grown near 

 or with the cotton ? 



Id. Has any effort beeen made to destroy the moth in its winter quarters ? 



7e. Have any systematic and organized attempts been made to gather and destroy 

 the chrysalides, or to facilitate their collection and destruction by furnishing inviting 

 material for the worms to sp n up in ? 



?/. What has been done toward destroying the eggs ? 



7g. Has anything been found more generally useful and applicable or chearper than 

 the use of the Paris green mixture to destroy the worms. 



7h. Have you known of any injurious effects following the use of this poison, either 

 to the plant, to man, or to animals ? 



7i. State what you consider the best and most effective method of destroying them 

 in your section. 



7;. State the cost per acre of protecting a crop by the best means employed. 



EF 3 IVe shall be glad to receive figures, either photographs or drawings, of machines or con- 

 trivances employed for the wholesale use of the Paris green mixture, either in the fluid state or 

 as ti powder ; or any other kinds of machines or traps employed for the destruction of the in- 

 sect. Models of such are still more desirable, and may be sent by express unpaid to the de- 

 partment.
