This data was generated to test how hybridization of an introduced insect biological control agent impacts host use. The data characterize the species composition of individual Diorhabda spp. collected across New Mexico and Texas, USA. Species composition of each individual was determined using genomic methods and Structure. Lab reared colonies were tested for host specificity, by measuring feeding preference in 24-hour feeding tests and measuring frass deposited below three host plants. Data on several attributes were also collected, including body mass, fecundity during the 24-hour feeding trial, and oviposition preference. The larval offspring of these individuals were also reared in families for 12 days on the three host plants and larval survival and mass were measured to quantify larval performance on the hosts.

Intended use

This data was collected to analyze how hybridization of an introduced biological control agent impacts host use, including adult feeding preference and larval performance. It can be used to look at hybridization across the landscape at one time point, and be combined with other datasets to look at hybridization over time. It can also be used to look at palatability of three host plants, feeding and oviposition preference of adults, and larval performance on the same plants.

Use limitations

There are several limitations to this data. First, the larval performance data on the target host (tamarisk) was highly influenced by plant quality. Due to a spider mite outbreak in the greenhouse during this portion of the experiment, the plant quality was very low. Additionally, the larval performance data primarily come from one population. Adult feeding preference was only measured for females. Oviposition preference data was collected over only 24 hours, which may not reflect true oviposition preference. Similarly, all these experiments were conducted under artificial lab conditions. It is known that these conditions can impact preference and feeding on non-target hosts. Other limitations of the data are described in the text of the main article.
