sutntner from 10 to 15 days. The second brood winters or 

 hibernates in the pupa condition. 



The habits of this insect offers favorable means for over- 

 coming- its ravages. The eggs laid upon the lower leaves- 

 may, in small orchards, be collected |>y hand. A little prac- 

 tice soon makes a person proficient in observing the eggs. 



The habit of the caterpillars of descending the tree for 

 the last m:>lt, and possibly the one before the last, offers a 

 most convenient means of destroying them, for as long as4wo< 

 days may be spent in the molting operation. The leaf eating; 

 habit is taken advantage of by spraying the foliage with, 

 arsenites, such as Paris Green and Arsenate of Lead. A spray: 

 of a mixture of one- fourth pound of Paris Green, one-fourtb 

 pound of Quick Lime, and fifty gallons of water will be found 

 a very efficient remedy. In large orchards of old trees steam- 

 spraying outfits will be found advantageous. 



A number of natural enemies attack this insect in egg y 

 larval, and pupa stages. The following parasites have been 

 bred from different stages of the insect: Telenomus gossypii 

 cola, an active egg parasite, Heteropelma datanae, upon the 

 larvae and pupae, Archytas hystrix and Frontina frenchii 

 (two Tachina flies) upon larvae and pupae. 



The yellow Cuckoo or Rain Crow (Coccyzus Americanus-) 

 is a veritable enemy of the caterpillars, and should receive 

 the protection of pecan growers. 



The Fall Web Worm is a general vegetable feeder attack- 

 ing a variety of trees in the State. Its attack upon pecan 

 trees is rather vigorous, and if not remedied the defoliation, 

 and webs become very unsightly, to say nothing of the injury: 

 done. As the name "Web Worm" would indicate, the cater- 

 pillars live in webs which enlarge with the growth of the 

 caterpillars, and the necessity for food demand. This insect 

 should not be confused with the pecan or walnut caterpillar r 

 though both may occur on the same tree. The latter never 

 lives in a web, and may be found after the third molt on all 

 parts of the tree, while the web worm -gctnfines itself during: 

 the larval life to the web. Like the pecani oiv walnut cater- 

 pillar, the Fall Web Worm pupates below the surface ofc the:
