From April to August 2017 the study was conducted the aim of which was intended to identify representatives of phytophagous family Chrysomelidae using trophic purpose, vegetative parts of plants growing in field collections of introduced and cultivated species. To identify trophic relations of beetles with the potential host plants to find the potentially dangerous pests when introducing new plants into culture. Studies of leaf beetles in the territories of Botanical gardens, parks and squares of Voronezh identified 15 species of Coleoptera, using trophic purpose, vegetative parts of green space. Six species of beetles from among the following indigenous fauna were first observed on the leaves of introduced plants.

Reliable host plant records are available for only a small fraction of herbivorous insect species, despite their potential agricultural importance. Most available data on insect–plant associations have been obtained through field observations of occurrences of insects on particular plants. Molecular methods have more recently been used to identify potential host plants using DNA extracted from insects, but most prior studies using these methods have focused on chewing insects that ingest tissues expected to contain large quantities of plant DNA. Screening of Illumina data obtained from sap feeders of the hemipteran family Cicadellidae (leafhoppers) using anchored hybrid enrichment indicates that, despite feeding on plant fluids, these insects often contain detectable quantities of plant DNA. Although inclusion of probes for bacterial 16S in the original anchored hybrid probe kit yielded relatively high detection rates for chloroplast 16S, the Illumina short reads also, in some cases, included DNA for various plant barcode genes as “by-catch”. Detection rates were generally only slightly higher for Typhlocybinae, which feed preferentially on parenchyma cell contents, compared to other groups of leafhoppers that feed preferentially on phloem or xylem. These results indicate that next-generation sequencing provides a powerful tool to investigate the specific association between individual insect and plant species.

With the exception of a handful of economically important species, the biology of cixiid planthoppers (Hemiptera: Fulgoroidea: Cixiidae) is poorly known. The host plants and life history ofCixius meridionalisBeirne were investigated in a wetland in Soldotna, Alaska. Specimens were collected over the course of the growing season by hand, aspirator, Berlese funnel, and sweep net. A handful of live nymphs were placed in a terrarium containing potential host plants for direct observation of feeding.C. meridionaliswas found to feed on roots ofPicea mariana(Mill.) Britton, Sterns & Poggenb,Empetrum nigrumL.,Chamaedaphne calyculata(L.) Moench, andVaccinium vitis-idaeaL. At least within the study area,C. meridionalisappears to require multiple years to reach adulthood, with overwintering in nymphal instars.C. meridionaliswas occasionally tended byMyrmica alaskensisWheeler.
