  Several plant bug species (Miridae) are important pests of crops and vegetables, thus monitoring them is of essential importance for effective pest control. During the current, preliminary study synthetic plant volatile combinations were tested in field conditions in Hungary in alfalfa fields. Beside semiochemical baited traps, sweep-netting was also performed. In the experiments three plant bug species were found in higher numbers: Adelphocoris lineolatus, Lygus rugulipennis and L. pratensis. As a novel, interesting finding L. pratensis was attracted to phenylacetaldehyde baited traps. For all species, both males and females were trapped in all combinations. Sweep-netting and semiochemical baited traps showed different efficacy in case of the three species, as sweep-netting catches were highly biased for A. lineolatus, which indicates the higher efficacy of this method as compared to the tested semiochemical-baited traps. On the other hand, semiochemical baited showed better performance for L. rugulipennis and L. pratensis. For these species none of the tested combinations performed better than phenylacetaldehyde baited traps. The potential implication of results in view of monitoring are discussed.

  The cultivated plant climate association in agricultural yields is getting expanded consideration with regards to changing climatic conditions. Abiotic stressors can lead to morpho-anatomical, physiological, and biochemical alterations in harvests, resulting in a significant loss of profit. A comprehension of ecological elements and their communication with physiological cycles is critical for improving agricultural practices. Drought stress is among the main natural factor affecting plant development, growth, and yield measures. Assessing the impact of environmental change and atmospheric variability on tomato crop output will require a thorough understanding of this stress element. The physiology, development, improvement, yield, and quality of the tomato crop are all affected by dry season stress. This mini-review essay presents the most prominent features about the effects of drought stress on tomato crop plant physiology and production, with specific highlighting for the complex relationship between drought stress, and nutrients uptake.
