Abstract:

A greenhouse study was conducted to quantify the relationship of peanut (Arachis hypogaea L. var Florunner) plant damage to plant phenology and lesser cornstalk borer, Elasmopalpus lignose/lus (Zeller), larval density. Five plant growth stages, five lesser cornstalk borer (LCB) larval densities, and nine replicates were used in the study. Overall survival of larvae to adulthood was 46.90 ± 0.02% (x ± SEM). Less than 3.60% of pods were damaged when ≥4 larvae were used to infest a plant, whereas ≥7.08% were damaged when 6 or 8 larvae were used. A greater percentage of plants infested at stage ≥R5 had damaged seeds than those infested at ≥R3. Undamaged pod and seed, and root dry weight declined linearly with an increase in LCB density. An economic injury level of 3.63 to 5.44 larvae per row-meter was calculated based on 5.82% loss in undamaged pod dry weight per LCB.
