Abstract
New strategies for protecting crops from aphid attacks must be developed. The present study aimed to examine the effect of cis-Jasmone (CJ), an activator of plant defense, on potato plants. Plants were sprayed with an exogenous application of CJ at 12, 24, and 48 h; and the green peach aphid, Myzus persicae Sulzer, and its parasitoid, Aphidius gifuensis, were used to evaluate the tri-trophic interactions of the aphids, parasitoids, and plants. In this work, we examined that the adult M. persicae produced fewer nymphs on CJ-treated plants at 12, 24, and 48 h than on control plants. Furthermore, M. persicae nymphs that fed on CJ-treated plants at 48 h had a lower mean relative growth rate (MRGR). Moreover, the intrinsic rate of population increase (r) was significantly lowered in CJ-treated plants at 12, 24, and 48 h. CJ-treated plants at all time durations showed considerably less settlement of aphid than control plants. In the olfactometer bioassay, the parasitoid exhibited a prolonged duration in the arm treated with volatiles from CJ-treated plants at 12, 24, and 48 h in comparison to the control. Moreover, the salicylic acid and jasmonic acid marker gene expression levels were significantly upregulated by CJ-treatment. Surprisingly, aphids raised on CJ-treated potato plants showed higher transcriptional levels of detoxifying enzymes. The findings of this research will provide new insights into the possible applications of important volatile components like cis-jasmone in integrated pest management systems, in addition to enhancing our comprehension of the ways in which plant volatiles affect the crop community.
期刊介绍:
The Editors of Crop Protection especially welcome papers describing an interdisciplinary approach showing how different control strategies can be integrated into practical pest management programs, covering high and low input agricultural systems worldwide. Crop Protection particularly emphasizes the practical aspects of control in the field and for protected crops, and includes work which may lead in the near future to more effective control. The journal does not duplicate the many existing excellent biological science journals, which deal mainly with the more fundamental aspects of plant pathology, applied zoology and weed science. Crop Protection covers all practical aspects of pest, disease and weed control, including the following topics:
-Abiotic damage-
Agronomic control methods-
Assessment of pest and disease damage-
Molecular methods for the detection and assessment of pests and diseases-
Biological control-
Biorational pesticides-
Control of animal pests of world crops-
Control of diseases of crop plants caused by microorganisms-
Control of weeds and integrated management-
Economic considerations-
Effects of plant growth regulators-
Environmental benefits of reduced pesticide use-
Environmental effects of pesticides-
Epidemiology of pests and diseases in relation to control-
GM Crops, and genetic engineering applications-
Importance and control of postharvest crop losses-
Integrated control-
Interrelationships and compatibility among different control strategies-
Invasive species as they relate to implications for crop protection-
Pesticide application methods-
Pest management-
Phytobiomes for pest and disease control-
Resistance management-
Sampling and monitoring schemes for diseases, nematodes, pests and weeds.
