Effects of three insect control schemes on populations of cotton insects 

 and spiders, fruit damage, and yield of Westburn 70 cotton. Environ. 

 Entomol. 5: 508-510. 

 Numbers of predatory insects (lady beetles, primarily Hippodamia spp.; green 

 lacewings, Chrysopa spp.; nab ids,. Nab is spp.; soft-winged flower beetles, 

 Collops spp.; hooded beetles, Notoxus monodon F.; big-eyed bugs, Georcoris 

 spp.), spiders (unidentified), and fleahoppers, Pseudatomoscelis seriatus 

 (Reuter) were determined weekly in cotton grown under 3 insect control schemes. 

 Numbers of fruits damaged by the Heliothis complex (the bollworm, Heliothis 

 zea (Boddie), and the tobacco budworm, H. vircscens F.) and by the boll weevil, 

 Anthonc r us grand is Boheman were also determined. The 3 control schemes used 

 were (1) strip-planted with grain sorghum, (2) solid-planted, insecticide 

 treatments according to OSU Agriculture Extension Service recommendations, 

 and (3) solid-planted, no insecticide treatments. Significantly greater 

 numbers of predators occurred in the strip-planted plots. Overall diffe- 

 rences in fleahopper numbers and fruit damage by the Heliothis complex were 

 Insignificant. Damage by the boll weevil was negligible. Yield per acre in 

 the strip-planted test was higher at P=0.10 than in either of the other tests. 

 In addition, an avg. 5308 lbs/acre of grain sorghum was produced in the strip 

 planted plots.

CAlco Oil Red N-1700. J. Econ. Entomol. 73: 664. 

 Boll weevils, Anthonomus grand is grand is Bohoraan, were marked in growing cotton 

 without any manual or mechanical manipulation of the insect by injecting Calco 

 Oil Red N-1700® dye into the square with a syringe. After 21 days as an adult.
