Abstract
At present, Acrobasis advenella (Zinck.) (Lepidoptera, Pyralidae) is the most dangerous pest of black chokeberry (Aronia melanocarpa [Michx.] Elliot). Damaged flower buds may decrease yield, while pest feeding inside fruits causes deterioration in their quality. The aim of the study was to determine and compare the effect of water and acetone plants extracts and essential oils using free choice tests of feeding site of larvae and oviposition of females. The following species were examined: Achillea millefolium, Cymbopogon citratus, Nepeta cataria, Origanum vulgare, Satureja hortensis, Tagetes patula nana, Tanacetum vulgare and Thymus vulgaris. The results showed that plant species had a significant influence on the choice of oviposition and feeding site of A. advenella. Moreover, the type of formulation affected the number of laid eggs. Females did not lay eggs on infructescences treated with acetone extracts. Among the test preparations, the highest percentage larvae and adults of A. advenella was recorded for plants soaked in C. citratus, and therefore it can be a potential attractant for this pest species. The lowest number of eggs and larvae was observed for T. vulgare.
Highlights
The introduction of chemical plant protection products into the natural environment results in the disruption of biological balance, and poses a great threat to human health, animals and the environment
Statistical analysis of the results did not confirm a significant difference in the number of laid eggs in relation to the diluent (Table: Supplementary data)
The highest number of eggs was laid by females on fruits treated with C. citratus (32.36%) (Fig. 1)
Summary
The introduction of chemical plant protection products into the natural environment results in the disruption of biological balance, and poses a great threat to human health, animals and the environment. They cause major damage to ecosystems and groundwater. Chemical methods contribute to the destruction of useful fauna as well as contamination of agricultural products (Nicolopoulou-Stamati et al 2016; Carvalho 2017). Due to the unfavorable effect of pesticides, non-chemical methods play an increasingly important role in pest control. The use of natural compounds in place of synthetic insecticides can reduce environmental pollution, and they are safe for human and animals health (Liao et al 2017; Kunbhar et al 2018).
