“…[7][8][9][10] Furthermore, excessive use of pesticides leads to environmental pollution and induces insecticide resistance. [11][12][13] Therefore, alternative integrated control methods including host plant resistance, 14 mass trapping, 15 mating disruption, 16 biological control and biorational pesticides 17 are needed. According to Blazhevski et al 18 combining biological control, cultural methods, and cultivar resistance can provide effective integrated control for this pest.…”

BACKGROUNDDue to the considerable damage of tomato leafminer in tomato crop, the use of integrated methods is essentially recommended. In this study, the effect of three different elicitors, i.e., methyl jasmonate (MJ), salicylic acid (SA) and ascorbic acid (AA) on the life table parameters of Tuta absoluta were evaluated. The paired bootstrap test and the different bootstrap percentiles were used to compare the projected population sizes on specific date. The survival probabilities were calculated by innovatively linking of life table and multinomial theorem.RESULTSThe preadult duration and mortality significantly increased, and the net reproductive rate (R0), intrinsic rate of increase (r), and finite rate of increase (λ) significantly decreased in all elicitor treatments. The lowest fecundity (F = 71.89 eggs/female) was observed in SA treatment, with R0 of 13.48 offspring/individual, r of 0.0932 d‐1, and λ of 1.0977 d‐1. The population projection revealed the stage structure of T. absoluta during population growth and the elicitor treatments significantly reduced the population growth of T. absoluta. The survival probability of bootstrap samples significantly lowered; whereas, the extinction probabilities increased in elicitor treatments than control when the survival criterion is set to two fertile pairs.CONCLUSIONOur results demonstrated that the application of elicitors could reduce the risks of the T. absoluta damage. Furthermore, population projection based on life tables is applicable to obtain the frequency distribution of population size at different times. The joined application of life table and multinomial theorem can be used to calculate the risk of pest emergence.This article is protected by copyright. All rights reserved.

“…Resources, such as water, nutrients, and light, are important for the growth and development of plants ( Kozlowski and Pallardy, 1997 ; Kozlowski and Pallardy, 2002 ; Salazar-Mendoza et al., 2023 ). With changes in resources availability, plants exhibit morphological, physiological, and biochemical changes, consequent changes in metabolites, enzymes, and behaviors, and ultimately adaptive changes in phenotype and genotype ( Vierling and Kimpel, 1992 ; Salazar-Mendoza et al., 2023 ). The physiological and biochemical changes in host plants can induce ecologically important responses of parasitic plants ( Evans and Borowicz, 2015 ; Zhang et al., 2023 ) and result in indirect effects of host plants on the growth of parasitic plants ( Zagorchev et al., 2021 ).…”

IntroductionParasitic plants can damage crop plants and consequently cause yield losses and thus threaten food security. Resource availability (e.g., phosphorus, water) has an important role in the response of crop plants to biotic attacks. However, how the growth of crop plants under parasitism are affected by environmental resource fluctuation is poorly understood.MethodsWe conducted a pot experiment to test the effects of the intensity of Cuscuta australis parasitism and the availability of water and phosphorus (P) on soybean shoot and root biomass.Results and discussionWe found that low-intensity parasitism caused ~6% biomass reduction, while high-intensity parasitism caused ~26% biomass reduction in soybean. Under 5–15% water holding capacity (WHC), the deleterious effect of parasitism on soybean hosts was ~60% and ~115% higher than that under 45–55% WHC and 85–95% WHC, respectively. When the P supply was 0 μM, the deleterious effect of parasitism on soybean was 67% lower than that when the P supply was 20 μM. Besides, the biomass of C. australis was highest when both the water and the P availability were lowest. Cuscuta australis caused the highest damage to soybean hosts under 5 μM P supply, 5–15% WHC, and high-intensity parasitism. Additionally, C. australis biomass was significantly and negatively related to the deleterious effect of parasitism on soybean hosts and to the total biomass of soybean hosts under high-intensity parasitism, but not under low-intensity parasitism. Although high resource availability can promote soybean growth, the two resources have different impacts on the response of hosts to parasitism. Higher P availability decreased host tolerance to parasites, while higher water availability increased host tolerance. These results indicate that crop management, specifically water and phosphorus supply, can efficiently control C. australis in soybean. To our best knowledge, this appears to be the first study to test the interactive effect of different resources on the growth and response of host plants under parasitism.
