678. Moore, R. F. 1980. Apparatus for simultaneous determination of locomotor 

 acti/ity in multiple treatments of boll weevils.' J. Econ. Entomol. 73: 

 795-797. 



An apparatus is described that was designed to simultaneously determine with 

 replicaticn the locomotor activity of multiple groups of Anthonomus grandis 

 grand is Bcheman. In evaluation of the effects of the variables time for 

 response, number of boll weevils per replication, time of day of test, age 

 of weevils, and cleanliness ot test cages; optimum time for response was 20 

 min, optimum number of weevils per replication was 20 or less, and time of 

 day of test, age of weevils, and cleanliness of test cages had no effect.

 in control of the boll weevil. J. Econ. Entomol. 73: 265-267. 



Methyl parathion applied topically was much more toxic to adult Anthonomus grandis 

 grand is Boheman than NRDC-161 (S)-[cyano(3-phenoxyphenyl)methyl] cis- (+)-3-(2, 

 2-dibromoethenyl)-2, 2-dimethylcyclopropanecarboxylate) , but NRDC-161 was more 

 toxic to immature stages in laboratory media. NRJ)C-161 reduced fecundity of 

 females, was repellent, and toxic to eggs at 0.01 ppm.

 hormoni*- analogues on adult development. J. Ga. Entomol. Soc. 15: 227-231. 



Boll weevils, Anthonomus grandis Boheman, lacking abdominal sclerotization were 

 produced when Ath and 5th instars were fed diets containing from 0.01 to 100 

 ppm of one of the following chemicals: dif lubenzuron; AI3-63223 (2, 6-difluoro- 

 N-[ [ [4-trifluoromethyl)phenyl]araino]carbonyl]benzamide) ; HLR Ro-10-3108 

 (epof enonane) (2-ethyl-3- [ 3-ethyl-5- (4-ethylphenoxy)pentyl]-2-methyloxirane) ; 

 and Hercules 24108 (l-methyl-2-propynl (4-chlorophenyl) carbamate) .
