AbstractThe diamondback moth (DBM, Plutella xylostella L. (Lepidoptera: Plutellidae)) consumes a wide variety of brassicaceous host plants and is a common pest of crucifer crops worldwide. A highly unusual infestation of a sugar pea crop was recorded in Kenya in 1999, which persisted for two consecutive years. A strain (DBM-P) from this population was established in the laboratory and is the only one of several strains tested that can complete larval development on sugar peas. The oviposition acceptance and preference of the DBM-P strain was assessed in the presence of cabbage plants, sugar pea plants or both, in comparison to another strain (DBM-Cj) that was collected from cabbage and is unable to grow on pea plants. As expected, DBM-Cj females preferred to oviposit on cabbage plants. Surprisingly, DBM-P females also laid most eggs on cabbage and very few on peas. However, they laid significantly more eggs on the cabbage plant when pea plants were present. Our findings suggest that DBM-P manifested the initial stages of an evolutionary host range expansion, which is incomplete due to lack of oviposition fidelity on pea plants.

Habitat fragmentation increases the isolation of natural populations resulting in reduced genetic variability and increased species extinction risk. Behavioral innovation through learning, i.e., the expression of a new learned behavior in a novel context, can help animals colonize new suitable and increasingly fragmented habitats. It has remained unclear, however, how reduced genetic variability affects learning for colonizing more or less suitable habitats. Here, we show that inbreeding in a subsocial invertebrate, the spider mite Tetranychus urticae, reduces novel host plant colonization and reproductive fitness. When provided with the possibility to learn from previous experience with a host plant species, outbred mites showed aversive learning ability, but inbred mites did not adapt their behavior. We further found a putative general cost of learning in both inbred and outbred mites. Our results reveal that inbreeding affects the learning component of behavioral innovation for host plant colonization.
