Insect heart resonance appearance simulation of Colorado potato beetle (leptinotarsa, doryphora, decemlineata say)

Abstract

Insect’s class is the most numerous, comprising more than 1 million species. Insects have inhabited a variety of terrestrial habitats, soil, fresh water, coastal seas. A large variety of habitats in the terrestrial environment contributed to the speciation and the wide distribution of this large group of arthropods. Most insects benefit as plants pollinators, some of them produce substances (honey, wax, varnish, silk), which are used as food products and raw materials for industry. Through the large biomass and diversity of trophic relations, insects take part in the biosphere circulation of substances, in soil formation processes. Among the insects that do not benefit, there are pests of forest and agricultural crops, carriers of plant, animal and human diseases. For example, potato or Colorado potato beetle (Leptinotarsa, Doryphora, decemlineata Say). It belongs to the tongs family (Crysomelidae), up to 1 sm in length and up to 7 mm in width. Their body is reddish-yellow, elytra light yellow with 5 black longitudinal stripes; there are several black dots on their chest shield, sometimes merging into spots; the apex of thickening antennae and the posterior margin of the head are also black. The potato beetle was discovered and described in 1823 in the Rocky Mountains, where it inhabited and ate at the expense of wild-growing members of the nightshade family (Solaneae); later it switched to the colonists potato plantations. The first devastations produced by it were noticed in 1859 in the state of Colorado hence the name of the beetle.1–6 The Colorado potato beetle causes great damage to the potato crop. Destruction is an important issue. The Colorado potato beetle has a multi-chamber heart. We believe that this is the most vulnerable part of his body. The heartbreak leads to the death of the Colorado potato beetle. This determines the relevance of the chosen topic. The aim of this work was to simulate a multi-chamber system of insect heart, to determine the rigidity of its multi-chamber system and the resonant frequency.
