“…It is well known that the potato ladybird beetle Henosepilachna vigintioctomaculata Motschulsky, 1857 (Coleoptera:Coccinellidae) feeds on plants from various families [ 1 , 2 , 3 , 4 ] but prefers Solanum tuberosum L among all others [ 5 ]. Currently, there is no consensus on the reasons why phytophagous insects are so selective about host-plants.…”

Henosepilachna vigintioctomaculata is an intrinsic element in the agroecosystem of potato fields. The issues of relationships in the system “potato ladybird beetle—potato plant” have not yet been studied. To study the effect of potato varieties on the potato ladybird beetle, only hatched and active larvae with a hatching rate close to 100% were selected from a laboratory colony. Larvae of the first summer generation collected in potato fields were used in our study to determine the level of adrenaline in the bodies of insects, fresh potato leaves were used to study the content of glycoalkaloids, the content and activity of proteinase inhibitors. The larvae that fed on plants of varieties Belmonda, Queen Anne, Lilly, Dachny, Kazachok, Yubilyar, and Avgustin demonstrated the highest level of stress while the stress level in those that fed on variety Smak was the lowest. The damage inflicted by potato ladybird beetles on leaves of some studied potato varieties led to a progressive increase in the content of glycoalkaloids already within 24 h after the phytophages had been transferred. In most cases, the content of glycoalkoloids increased by 20% within five days. Potato ladybird beetles feeding on plants of different potato varieties caused a progressive increase in proteinase inhibitors (% of the control). Plants of variety Smak did not show a significant increase in the content of alkaloids in the herbage in response to the damage. A correlation was established between the mortality rate, the activity of proteinase inhibitors, the dynamics of glycoalkaloids, and the level of adrenaline, which could be formulated as follows: the higher the content of glycoalkaloids and the activity of proteinase inhibitors in the tissues of potato plants, the higher the level of stress in the potato ladybird beetles that feed on them.

Solanum tuberosum L. is susceptible to 40 different virus species and 2 viroids. To prevent plant viruses from spreading in field conditions, it is necessary to have reliable data on the species composition of plant reservoirs of viral infection, the total activity of insect vectors, and possible ways of virus transmission in a particular territory of seed material production. Attention should be paid to the factors that facilitate and hinder the disease development in crops and to disease symptoms in different potato varieties. Manifestations of viral infections were monitored on every plant from the sample at the stages of initial growth, bud formation, and flowering and before the removal of potato haulms. Insects were collected using standard entomological method. The total RNA was isolated employing commercial kits for the extraction of nucleic acids from plant material “PhytoSorb” (Syntol Llc) and the benchtop automated extraction instrument KingFisher Flex (ThermoScientific) with magnetic particles. Plant viral infection was observed to accumulate if potato planting material was not renewed. The tested potato plants contained mixed viral infection, which consisted of viruses from mosaic group: PVY, PVX, PVM, PVS PVA, as well as PSTVd and PLRV. Without the renewal of seed potatoes, the concentration of plant viruses in an agroecosystem rises and causes secondary infections in potato plants. The research identified the main insect-vectors in the agroecosystem of potato fields: insects from genera Cicadella, Henosepilachna vigintioctomaculata, Dolycoris baccarum, Mythimna separata, Lygus pratensis, and Rhopalosiphum padi. Many wild weeds serve as fodder plants for insect vectors facilitating the accumulation of plant viruses in agroecosystems. It was established that perennial weeds were the main plant reservoirs of dangerous viral infections, e.g. Sonchus arvensis and Taraxacum officinale. We determined that Trifolium pratense typus L., Chenopodium album L., Plantago major L., Barbarea vulgaris W.T. Aiton, and Ambrosia artemisiifolia L. were the reservoirs of PVY. All these factors can lead to an epiphytotic situation.

Glycoalcoloids of plant origin serve as teratogens, causing various teratoses and abnormalities of insect development. Our previous studies discovered dependence of developmental defects in the 28-spotted potato ladybeetle Henosepilachna vigintioctomaculata upon its feeding on certain potato varieties. The present study was undertaken to study the toxic effect of α-tomatine against the 28-spotted potato ladybeetle. Tomatine was chosen as a model glycoalkaloid. Potato leaves were treated with tomatine solutions in different concentrations. Control leaves were treated with distilled water. Ten first-instar larvae were placed in a Petri dish with treated leaves. The effect of tomatine on H. vigintioctomaculata was assessed by appearance of morphological abnormalities in the adults. As a result, a confident direct correlation between the tomatine concentration and the developmental defect frequency was found. Brachelytry and cystelytry were the main anomaly types. When the stock 6 % solution was used, insect mortality was the highest, reaching 70 %. The highest level of teratoses (60 %) among survived insects and relatively high mortality (27 %) were observed in insects treated with 0.6 % solutions of tomatine. As the tomatine concentration decreased, so did the mortality level and developmental defect frequency. At 0.06 % solution treatement, mortality was 17 % and quote of teratoses – 47 %, at 0.006 % – 16.6 % and 6.8 %; at 0.0006 % – 3.3 % and 3.4 %, respectively. Thus, tomatine can be used as an insecticidal compound for potato cultivation.
