ton SPOTTED BOLLWORM, "EARIAS FABIA" (LEPIDOPTERA: NOCTUIDAE), IN 

 RELATION TO ITS ESTABLISHMENT ON VARIOUS PLANTS. Ent. Exp. Appl. 13: 



10-20. 

 Among the plant parts tested, Abelmoschus esculentus Moench., fruit, and 

 Gossypium hirsutum leaves appeared the most suitable for oviposition by 

 Earias fabia (Cramer) because of their great hair density and the presence 

 of certain chemicals.

strains to the boll weevil. J. Econ. Ent. 56: 860-862. 

 The Pilose- Okra leaf strain of Gossypium sp. (with single dominant genes 

 for pilose) had a low percentage of squares punctured under conditions of 

 low weevil population pressure; when infestations of Anthonomus grandis in- 

 creased on other plots, a rapid increase also occurred on these plants.

in the sudan gezira. Emp. Cotton Grow. Rev. 42: 33-40. 

 Gossypium barbadense lines with hairy leaves provided shelter for adult 

 Bemisia tabaci. These whiteflies left glabrous- leaved varieties more readily 

 than they left pubescent cultivars.

 Two pairs of genes appeared as part of the genetic control of pubescence 

 of leaves in the crosses of Gossypium hirsutum studied.

DAMAGE DONE BY THE BOLLWORM TO GLANDED AND GLANDLESS COTTONS. J. 



Econ. Ent. 63: 1328-1329. 

 In view of previous indications of reduced oviposition on Gossypium spp. 

 with glabrous leaves, it was suggested that the glandless version of a smooth- 

 leaved variety would be less susceptible to Heliothis zea than the more com- 

 monly grown hirsute glanded cottons.

pests to jassid resistant sakel. Emp. Cotton Grow. Rev. 33: 197-202. 

 Jassid-resistant (hairy- leaved) lines of Gossypium barbadense were sus- 

 ceptible to Aphis gossypii, Bemisia tabaci, and Tetranychus sp. The impor- 

 tance of developing a jassid-resistant variety not more susceptible to other 

 insects was stressed.

sid resistance in relation to hairiness of cotton leaves. Euphytica 

 15: 383-388. 

 Of three characteristics of hairiness studied, length of hair appeared to be 

 of prime importance, followed by density of hair on the lamina. Pubescence 

 on the midrib did not seem an important role in imparting resistance of Gos- 

 sypium hirsutum to Amrasca devastans (Distant). 



(48) Stephens, S. G. 1957. sources of resistance of cotton strains to the boll 



weevil and their possible utilization. J. Econ. Ent. 50: 415-418. 

 Red plant color, plant hairiness, and absence of stem glands in Gossypium 

 spp. were involved in resistance to Anthonomus grandis.
