Abstract
The research aim is to improve the system of chickpea protection from pests, based on clarification of their specific composition and harmfulness under conditions of Forest-Steppe of Ukraine.
 In modern field crop rotations leguminous crops cultivation favors optimization of the phytosanitary condition of agrocoenosis, and new agrarian production is provided by the effective demand for grain at not only internal, but also external markets. At that climate changes with global warming and long droughty vegetation periods of leguminous crops testify to the importance of searching for new adapted crops, resistant sorts and improved technological cultivation methods of crops, especially, chickpea, essentially influencing grain economy in whole both in Ukraine and EU.
 Thus, it has been established, that ordinary chickpea (Cicer arietinum L.) is an economically, phytomedically and ecologically expedient crop from both aspects of soil fertility increase and control of the harmful organisms complex that, in its turn, it worth special attention, so sowing areas, occupied by it, are completely important. Soil-climatic conditions of Ukraine are optimal for cultivating native highly productive chickpea sorts, not inferior to foreign ones with the potential yielding capacity as 2.5–3.0 t/ha.
 The authors elucidate one of main control peculiarities of the insects-phytophagans under new agriculture systems. It is typical, that chickpea is a comparatively new crop in the Forest-steppe of Ukraine and doesn’t favor the development, propagation and number increase of specialized pests’ species. It is noted, that due to fluffing and extraction of organic acids by leaves, chickpea manifests protective properties as to pests of leaves and generative organs. But chickpea is damaged by polyphagans with harvest losses in several variants up to 50% that testifies to the elaboration topicality of modern system of crops protection from phytophagans at resource-saving cultivation technologies
Highlights
The obvious tendency to climate change with global warming needs revision of technological methods of chickpea cultivation, especially system of protective arrangements, sowing terms, standards and methods, care of crops and so on, and needs a search for technological solutions as to crop adaptation to new structures of entomocomplexes that essentially influences the effectiveness of grain economy in the Forest-steppe of Ukraine [1].the temperature regime increase and duration change of droughty periods in the vegetation season of l crops need searching for new crops, non-traditional for the cultivation region, especially such as chickpea and other grain legumes
Specific composition of phytophagans in 2017–2019 the complex of phytophagans, colonized and damaged chickpea crops were revealed at the experimental field
Changes of the chickpea phytophagans structure during the vegetation period were established by peculiarities and growth intensity of the plants
Summary
The temperature regime increase and duration change of droughty periods in the vegetation season of l crops need searching for new crops, non-traditional for the cultivation region, especially such as chickpea and other grain legumes. It is most important for economies of all property forms to cultivate resistant zoned sorts of agricultural plants, and to use a substantiated system for controlling insects’-pytophagans’ complexes by organogenesis stages of their cultures, especially under unfavorable agroclimatic conditions of the last years – for increasing their yielding capacity [1,2,3,4]. The biological value of protein reaches 52–78 %. [2,3,4, 6,7,8]
