“…In herbivore species, these compounds inhibit digestion (Napoleão et al, 2019;Gómez et al, 2020), and can affect the reproductive capacity and organism development (Cui et al, 2019;Mikani, 2019;Riddick, 2021;Stec et al, 2021), among other biological interferences. Furthermore, it represents a chemical defense barrier, enhancing plant's resistance to microorganisms, insects, and other herbivore animals (Yao et al, 2019;Marcucci, et al, 2021;Ramaroson et al, 2022;Vengateswari et al, 2022).…”

The coffee red spider mite, Oligonychus ilicis, stands out as one of the main pests of Conilon coffee. The use of synthetic chemical control has led to an increase in the population of this mite and a reduction in its natural enemies. Aiming to find viable alternatives, this study aimed to evaluate the acaricidal potential of “abricó” peel extract, Mammea americana, in the management of O. ilicis. Each treatment consisted of 7 repetitions, with 10 individuals per repetition. They were placed in Petri dishes (10.0 x 1.2 cm), containing coffee leaf disks (4 cm diameter) inside, and moistened cotton at the bottom of the dish and around the disks. The peels of M. americana were dried, crushed, and diluted in aqueous solution to obtain extracts at concentrations of 2; 2.57; 3.30; 4.24; 5.45; and 7 %. The application was done by spraying, using an Alfa 2 model airbrush connected to a compressor calibrated with a constant pressure of 1.3 psi. 1 mL of solution of each concentration was applied for each repetition. Distilled water and the surfactant Tween® 80 (0.05 % v/v) were used as control treatments. The acaricidal effect was evaluated 24, 48, and 72 hours after spraying, and the lethal concentrations LC50 and LC90 were calculated. The results of the toxicity tests indicated an increase in the mortality of O. ilicis with the increase in the concentrations of aqueous extracts of M. americana, resulting in 100 % mortality. The LC90 was estimated at 3.83 %. In the chemical analysis of the M. americana extract, the presence of phenolic acids, tannins, and flavonoids was observed at concentrations of 39.150, 40.783, and 0.0349 mg-1, respectively. We conclude that the aqueous extract of M. americana peels demonstrated acaricidal potential in a controlled environment for the coffee red spider mite.

“…To induce the release of 12.8 nmol Z -3-HAL (the accumulation of 4.2 nmol Z -3-HAL in Arabidopsis leaves) and Ca 2+ signals under our experimental conditions, approximately 148.8 (992.3 mm 2 ) and 662.1 (4409.0 mm 2 ) mg of leaves need to be injured in tomatoes and Arabidopsis , respectively. This size of agricultural damage might be realistic in nature 53 .…”

Plants perceive volatile organic compounds (VOCs) released by mechanically- or herbivore-damaged neighboring plants and induce various defense responses. Such interplant communication protects plants from environmental threats. However, the spatiotemporal dynamics of VOC sensory transduction in plants remain largely unknown. Using a wide-field real-time imaging method, we visualize an increase in cytosolic Ca2+ concentration ([Ca2+]cyt) in Arabidopsis leaves following exposure to VOCs emitted by injured plants. We identify two green leaf volatiles (GLVs), (Z)-3-hexenal (Z-3-HAL) and (E)-2-hexenal (E-2-HAL), which increase [Ca2+]cyt in Arabidopsis. These volatiles trigger the expression of biotic and abiotic stress-responsive genes in a Ca2+-dependent manner. Tissue-specific high-resolution Ca2+ imaging and stomatal mutant analysis reveal that [Ca2+]cyt increases instantly in guard cells and subsequently in mesophyll cells upon Z-3-HAL exposure. These results suggest that GLVs in the atmosphere are rapidly taken up by the inner tissues via stomata, leading to [Ca2+]cyt increases and subsequent defense responses in Arabidopsis leaves.

“…Interestingly, treatment with digestive enzyme inhibitors attenuated differences in larval adaptation between high- and low-preference host plant groups, as shown by the fact that the AI and TI treatment reduced the difference in larval body weight from 65.77–135.17 mg to 38.66–74.14 mg between high and low feeding groups. A large number of studies have shown that compared with low-preference host plants, high-preference host plants have higher nutrient content and lower endogenous digestive enzyme inhibitor content [ 38 , 39 , 40 ]. After treatment with exogenous enzyme inhibitors, the H. cunea larvae could not effectively absorb nutrients from plants with high preference.…”

Digestive physiology mediates the adaptation of phytophagous insects to host plants. In this study, the digestive characteristics of Hyphantria cunea larvae feeding preferences on different host plants were investigated. The results showed that the body weight, food utilization, and nutrient contents of H. cunea larvae feeding on the high-preference host plants were significantly higher than those feeding on the low-preference host plants. However, the activity of larval digestive enzymes in different host plants presented an opposite trend, as higher α-amylase or trypsin activity was observed in the group feeding on the low-preference host plants than that feeding on the high-preference host plants. Upon treatment of leaves with α-amylase and trypsin inhibitors, the body weight, food intake, food utilization rate, and food conversion rate of H. cunea larvae significantly decreased in all host plant groups. Furthermore, the H. cunea comprised highly adaptable compensatory mechanisms of digestion involving digestive enzymes and nutrient metabolism in response to digestive enzyme inhibitors. Taken together, digestive physiology mediates the adaptation of H. cunea to multiple host plants, and the compensatory effect of digestive physiology is an important counter-defense strategy implemented by H. cunea to resist plant defense factors, especially the insect digestive enzyme inhibitors.
