HOST PLANT ADAPTATIONS AMONG GEOGRAPHIC POPULATIONS OF THE COLORADO POTATO BEETLE
Intraspecific variation in host plant adaptation of an oligophagous insect is interesting because it signifies adaptive changes among populations of a given species and may play a key role inExpand

Feeding specialization and host-derived chemical defense in Chrysomeline leaf beetles did not lead to an evolutionary dead end
Combination of molecular phylogenetic analyses of Chrysomelina beetles and chemical data of their defensive secretions indicate that two lineages independently developed, from an ancestral autogenousExpand

The Influence of Nutrient Chemicals on the Feeding Behavior of the Colorado Potato Beetle, Leptinotarsa decemlineata (Coleoptera: Chrysomelidae)
The influence of nutrient chemicals on the feeding behavior of the larva of the Colorado potato beetle, Leptinotarsa decemlineata (Say), was investigated using an agar-medium assay. Twenty-sixExpand

Selection and Specificity of the Colorado Potato Beetle for Solanaceous and Nonsolanaceous Plants
The acceptability by and suitability for larvae of the Colorado potato beetle, Leptinotarsa decemlineata (Say), of 104 plant species belonging to 87 genera and 39 families was investigated. Of theseExpand

The Role of Secondary Plant Substances in the Food Specificity of the Colorado Potato Beetle
An artificial diet without leaf materials, which supports moderate feeding and growth of fourth-instar larvae of the Colorado potato beetle, Leptinotarsa decemlineata (Say), was used to evaluate theExpand

Hybridization and cytoplasmic incompatibility among alfalfa weevil strains
Cross‐matings were conducted among eastern, western, and Egyptian alfalfa weevil strains. Fully viable progenies were produced in reciprocal crosses between eastern and Egyptian weevils. The crossExpand
