Consumption by Several Common Arthropod Predators of Eggs and Larvae of Two Heliothis Species1 That Attack Cotton23

Annals of the Entomological Society of America (1968)

P. D. Lingren R. L. Ridgway S. L. Jones

In laboratory experiments, several common arthropod predators consumed relatively large numbers of eggs and early-instar larvae of the bollworm, Heliothis zea (Boddie), and the tobacco budworm, H. virescens (F.). Predators confined with the hosts in small containers consumed more eggs and/or larvae than those confined with hosts on 10-inch cotton tci initials. However, all species were effective in reducing host populations on the terminals. Also, larval green lacewings (a mixture of Chrysopa Carnea Stephens and (C. rufilabris Burmeister) and adults of a lygaeid bug, Geocoris punctipes (Say), substantially reduced egg and larval populations of caged tobacco budworms. From the cage tests it was estimated that a release of about 420,000 Chrysopa larvae per acre had reduced the peak population of tobacco budworm eggs by 76% at 8 days after moth release. At 13 days, the larval population of the tobacco budworm had been reduced by 96%. A release of about 252,000 G. punctipes adults per acre was not so effective. However, a release of 630,000 G. punctipes adults and 420,000 Chrysopa larvae per acre reduced the egg and larval populations of the tobacco budworm by 88% and 99%, respectively.

Comparative Efficacy of Four Insect Predators of the Bollworm and Tobacco Budworm 1 , 2

Environmental Entomology (1976)

J. D. López R. L. Ridgway R. E. Pinnell

The comparative efficacy of 4 predators against 3 different stages of the cotton bollworm, Heliothis zea (Boddie), or the tobacco budworm, Heliothis virescens (F.), was studied in the laboratory. The species studied were Chrysopa carnea Stephens, Geocoris punctipes (Say), Coleomegilla maculata (DeGeer), and Podisus maculiventris (Say). Two of these predators were also evaluated for control of the tobacco budworm on cotton in field cages. Under limited searching requirements, C. maculata was generally the most efficient predator of Heliothis eggs and 1st stage larvae. However, when the 1st stage predators were compared, C. carnea was the most efficient predator on 1st instars. Third stage nymphs and adults of P. maculiventris were the most efficient predators of the 3rdstage larvae. Under expanded searching requirements, C. carnea larvae were the most efficient of the immature stages of predators on Heliothis eggs and 1st instars. As adults, C. maculata were the most efficient predators on eggs while G. punctipes were the most effective predators on 1st stage larvae. Third instars and adults of P. maculiventris consumed more 3rd instars of Heliothis than the other predators studied. Releases of C. carnea and P. maculiventris at rates of 100,000/acre in field cages resulted in substantial reductions in the number of tobacco budworm larvae. The reductions effected by C. carnea were more evident in the egg and small larva numbers while the reductions attributed to P. maculiventris occurred mainly when the tobacco budworm larvae were larger.
