To understand agroecology and to increase the role of entomophages in pest management, it is important to understand interactions among arthropod predators. Laboratory studies were conducted with 1–2 adult big-eyed bugs, (BEB) Geocoris spp., 1–2 striped lynx spiders (SLS), Oxyopes salticus Hentz (lst–3rd instar), or one of each to investigate conspecific and interspecific interference of predation on 1st instar Heliothis zea Boddie in the laboratory. The number of 1st instar H. zea consumed per individual in 24 h fell significantly when two adult BEB were confined together compared with the number consumed by solitary BEB. Placing two juvenile SLS together did not reduce the number of larvae consumed per individual in 24 h. The combined feeding rate of one BEB and one SLS confined together fell well below the sum of the rates for solitary BEB and SLS, but it was unclear to what degree each predator's feeding rate was reduced. These results suggest that exceeding the optimum density of BEB and SLS in the field could reduce the biocontrol of H. zea provided by BEB.

Hemileuca Oliviae

AbstractFlight of the range caterpillar occurred predominantly at dusk in the grasslands of eastern New Mexico in 1979 and 1980. The restricted period of flight in the evening corresponded to cool temperatures which probably favored mating success. Changes in atmospheric temperature and pressure had little effect on the number of moths flying from day to day. Most females oviposited within 10 m of the site of pupal eclosion.
