“…A number of Kunitz-related inhibitors from plants were evaluated in vitro for their potential of decreasing the activity of Lepdopteran/Coleopteran larvae digestive enzymes. SKTI (soybean Kunitz trypsin inhibitor) showed a potent in vitro inhibitory activity against A. grandis gut proteinases [11]. SKTI and CpTI (cowpea trypsin inhibitor) were shown to be active against tomato moth larvae (L. oleracea).…”

“…The use of proteinaceous inhibitors in insect control strategies has good potential, because insect digestive proteinases are promising targets in the control of various insects, including lepidopterans such as Manduca sexta [3], Heliothis zea [4], Spodoptera litura [5], and Lucilia cuprina [6], and also various coleopterans [7][8][9][10][11]. Despite several suggested physiological functions in plants [12][13][14], the inhibitors are known for their role in response to abiotic [15,16] biotic stresses, especially in plant defense processes against insect pest attack [9,[17][18][19][20].…”

The roles of signaling pathways in the production of trypsin proteinase inhibitors (TrypPIs) in rice infested by the leaf folder (LF) Cnaphalocrocis medinalis were studied. Infestation by LF increased TrypPI levels in the leaves of rice plants at the tillering, booting and flowering stages but decreased TrypPI levels at the ripening stage; TrypPI levels in rice stems did not increase at any developmental stage. Infestation by LF at the tillering stage systemically increased TrypPI levels in leaves but not in stems; it also enhanced salicylic acid (SA) levels in leaves and stems, and the ethylene level released from plants. However, LF infestation did not increase JA concentrations. Exogenous application of SA or ethylene enhanced TrypPI levels in the leaves and stems of plants at the tillering stage, whereas treatment with both SA and ethylene induced lower levels of TrypPIs than treatment with SA or ethylene alone, suggesting an antagonistic effect of SA and ethylene on TrypPIs induction. The results suggest that both SA and ethylene signaling pathways are involved in the production of TrypPIs in rice induced by LF; moreover, the antagonistic effect of SA and ethylene may explain the changes in TrypPI levels seen at different plant developmental stages and in different organs.rice, Cnaphalocrocis medinalis, jasmonic acid, salicylic acid, ethylene, trypsin proteinase inhibitor, herbivore-induced defense response Citation:Wang X, Hu L C, Zhou G X, et al.
