Bollworm: Peanut Foliage Consumption and Larval Development

  title={Bollworm: Peanut Foliage Consumption and Larval Development},
  author={F. R. Huffman and J. W. Smith},
  journal={Environmental Entomology},
Peanut foliage consumption by bollworm larvae, Heliothis zea (Boddie), increased from 176.1 to 195.1 cm2 and larval developmental time decreased from 35.3 to 30.2 days at 26° and 30°C, respectively. Pupal weights also increased with temperature. Larval instars ranged from 5 to 9 with no apparent change due to temperature. The penultimate and ultimate larval instars collectively consumed 73–97% of the total foliage consumed. The ultimate instar had the highest consumption rates ranging from 9.20… Expand
Resistance in Eight Peanut Genotypes to Foliar Feeding of Fall Armyworm, Velvetbean Caterpillar, and Corn Earworm
Differences in development to pupation and pupal weight were less distinct for CEW, and when CEW larvae were provided ten peanut blooms each 48 hours in addition to unlimited foliage, devel... Expand
Evaluation of defoliating caterpillar pests in Mississippi peanut
Two experiments were conducted at two locations in Mississippi to evaluate the impact of simulated defoliation on peanut yield and found defoliated plants impacted peanut growth as indicated by fractional green canopy coverage. Expand
Resistance of Wild Species of Peanut to an Insect Complex
Because collections in section Arachis were among the species with the highest resistance levels, utilization of the germplasm resources to improve cultivated peanuts should be possible. Expand

It seems possible that the safety margin for O2 delivery may disappear completely in the last hours before ecdysis, providing the ultimate if not proximate explanation for the necessity of molting. Expand
Ontogenic Changes in Feeding Behavior
The feeding behavior of insects changes, often radically, according to their stage of development, with individuals in different developmental stages differing as regards amounts and, often, theExpand
