It is a commonplace entomological observation that each phytophagous insect is restricted in its feeding to a small fraction only of the plant species that grow in any area. This phenomenon is generally referred to as “host selection”. The ecological significance of host plant selection among insects is manifest principally in an effect on the geographical distribution of insect species since phytophagous insects can occur only where suitable host plants are available.

The role of some plant properties in host plant selection by adults of the polyphagous H. armigera were investigated. Those factors found to positively influence host plant selection included presence of flowers, plant height and application of soil fertiliser. The presence of flowers greatly increased a plant's attractiveness to oviposition. Non-hosts, on which larvae did not survive, were readily oviposited on when offered in flower along with known hosts not in flower. The attractiveness of flowers may provide a mechanism for the expansion of host range. However, no effect of crude plant extracts (including various flowers) on oviposition could be detected. The role of chemical attractants is discussed. Tall plants attracted heavy oviposition and it is suggested that moths use silhouette as a cue to locating plants. There was no effect of plant water status on oviposition.

Underlying Mechanisms

There is increasing evidence that plant-associated microorganisms play important roles in shaping interactions between plants and insect herbivores. Studies of both pathogenic and beneficial plant microbes have documented wide-ranging effects on herbivore behavior and performance. Some studies, for example, have reported enhanced insect-repellent traits or reduced performance of herbivores on microbe-associated plants, while others have documented increased herbivore attraction or performance. Insect herbivores frequently rely on plant cues during foraging and oviposition, suggesting that plant-associated microbes affecting these cues can indirectly influence herbivore preference. We review and synthesize recent literature to provide new insights into the ways pathogenic and beneficial plant-associated microbes alter visual, olfactory, and gustatory cues of plants that affect host-plant selection by insect herbivores. We discuss the underlying mechanisms, ecological implications, and future directions for studies of plant-microbial symbionts that indirectly influence herbivore behavior by altering plant traits.
