Relationship Between Performance of Carob Moth, Ectomyelois ceratoniae Zeller (Lepidoptera: Pyralidae) and Phytochemical Metabolites in Various Pomegranate Cultivars

Abstract

The carob moth, Ectomyelois ceratoniae Zeller (Lepidoptera: Pyralidae), is the main pest of pomegranate, Punica granatum L., in Iran and many parts of the world. In this study, the effects of 11 commercial cultivars of pomegranate (Aban-Mahi, Esfahani-Daneghermez, Gabri, Gorche-Tafti, Malase-Danesyah, Malase-Yazdi, Shahvare-Daneghermez, Shahvare-Danesefid, Tabolarze-Mehrmahi, Tafti, and Toghe-Gardan) were evaluated on life history variables, nutritional performance, and energy reserves of E. ceratoniae under the following laboratory conditions: 30 ± 1°C, 60 ± 5% RH, and a photoperiod of 14:10 (L:D) hours. In addition, biochemical characteristics of the tested cultivars were assessed in order to understand any possible correlation between important demographic parameters and nutritional properties with biochemical features of pomegranate juice. Our research showed that various pomegranate cultivars have significant effects on life history, demographical parameters, nutritional indices, and energy reserves of E. ceratoniae. The shortest development time was observed on Shahvare-Danesefid cultivar and the longest was on Esfahani-Daneghermez and Malase-Danesyah cultivars. The highest intrinsic rate of increase (rm) was observed on Shahvare-Danesefid and the lowest was on Esfahani-Daneghermez. Six major anthocyanin compounds were detected in juice of various pomegranate cultivars. Significant positive or negative correlations were observed between life history variables and nutritional characteristics with biochemical traits of pomegranate cultivars. The results indicated that Shahvare-Danesefid was a relatively susceptible pomegranate cultivar and Esfahani-Daneghermez was the least appropriate (most resistant) cultivar for feeding of E. ceratoniae, which could be useful in the development of integrated pest management strategies for this pest.

Interaction between biological parameters of Panonychus citri (Acari: Tetranychidae) and some phytochemical metabolites in different citrus species

“…(2018), and Abedi et al . (2019) are in agreement with this result. Increasing growth period of immature stages can be detrimental to CRM.…”

“…The current research reveals the presence of interactions between phytochemical metabolites of various citrus host plants with development rate, fecundity, and life table parameters of CRM. Complex interactions of nutrients with other nutritional features can influence life cycle and reproductive rate of herbivore (Chen et al ., 2009; Abedi et al ., 2019). Host plant phytochemical metabolites can be an effective factor for the feeding and development of herbivores (Soufbaf et al ., 2012; Golizadeh and Abedi, 2017).…”

“…Host plant resistance is an environmentally and economically acceptable method in pest management and can be accompanied by other non-toxic approaches such as cultural, mechanical, or biological control methods in IPM (Golizadeh et al ., 2009; Soufbaf et al ., 2010; Abedi et al ., 2019). The use of resistant host plants is the most effective component of IPM (Vieira et al ., 2011).…”

“…The host plant quality directly affects the life table traits of pests that are of high importance in ecological studies. Life table parameters such as net reproductive rate ( R 0 ) and intrinsic rate of increase ( r ) determine the potential of a stable population to grow and reproduce in different circumstances, which help us determine the resistant citrus species and varieties against herbivores (Golizadeh et al ., 2017; Abedi et al ., 2019; Heidari et al ., 2020). Therefore, the determination of pest-resistant host plants is a basic need in pest management.…”

Physicochemical Properties of Sugarcane Cultivars Affected Life History and Population Growth Parameters of Sesamia nonagrioides (Lefebvre) (Lepidoptera: Noctuidae)

“…Plant physicochemical properties including primary and secondary metabolites, as well as trichome density, tissue hardness, and moisture content can determine the oviposition behavior and population performance of insect pests [ 24 , 25 , 26 , 27 , 28 ]. Therefore, study of these parameters, as resistance indices, could be useful in the identification of resistant cultivars for use in IPM programs [ 29 , 30 , 31 , 32 ].…”
