In recent years, a major effort has been directed towards the development of cotton strains having resistance against bollworms (Heliothis zea Boddie and H. virescens Fabricius). Some recent reports have attribute the resistance of some cotton strains to unknown ("X-Factors") resistance factors. The possibilities of utilization of these newer sources might be limited unless basis of this type of resistance is known. An important aspect of breeding for insect resistance is the separation of host plant resistance per se from the part played by predators in destroying eggs and young larvae. The ability of a plant to attract more predator s might still be an important facet of host plant resistance but it is important to clarify this type of resistance. Many reports in cotton have documented the useful presence of predators in pest management. One objective of our study was to compare the number of adult lady beetles (Family Coccinellidae) on different cotton genotypes. In an another study we wanted to observe if a water soluble compound on the leaves and terminals of PD 695 was involved in its resistance ("X-factors") against bollworms. Our interest in this study stemmed from observations in tobacco where presence of a water soluble sucrose ester on leaves is involved in budworm resistance and observations that bollworm resistance in PD 695 is not effective during rainy seasons.
