“…Kawai et al (1993) reported that S. exigua could invade the leaf blades and the infestation was contagious among the onion hills. Similarly, several subsequent studies reporting the infestation incidents of S. exigua on onions confirmed that onion is a host plant for this notorious pest ( Zheng et al, 2000 ; Ueno, 2015 ; Ilmi et al, 2022 ). These reports of the host shifting suggest the strong polyphagous and well-diverse host adaptability of the Spodoptera spp.…”

Plant-endophyte symbiosis influences plant defense and growth. Serendipita indica is a root endophyte that promotes growth and induces tolerance against biotic and abiotic stress in plants. In this study, we examined the effect of S. indica colonization on herbivore (Spodoptera exigua) resistance of onion (Allium cepa L.). We found that colonization of S. indica in the roots of onion significantly reduced the feeding damage of leaves by S. exigua larvae, and also resulted in a reduction in weight gain of the larvae when fed on S. indica plants. This enhanced resistance is a result of modulation of antioxidant and defense enzymes/genes in the host by S. indica mutualism. Specifically, the activities of enzymes such as Superoxide dismutase, peroxidase, polyphenol oxidase, phenylalanine ammonia-lyase, and H2O2 content were significantly higher in the early stages of S. exigua feeding in the S. indica colonized plants compared to the non-colonized counterparts. Similarly, defense genes also showed modulation in response to this tripartite interaction of onion -S. indica mutualism and S. exigua herbivory. The hierarchical cluster analysis and principal component analysis indicated a clear difference in the onion biochemical responses, which is due to the S. indica symbiosis. Our investigation demonstrates that onion-S. indica symbiosis significantly decreases chewing injury by efficiently modulating antioxidant and defense enzyme activities and gene expression in response to S. exigua herbivory. Therefore, S. indica can be used as a potential biocontrol agent for sustainable management of this important pest of Alliums.

“…et Kir. [49]. The prospect of using A. roylei as a source of resistance to T. tabaci in onion breeding is promising, but further research is needed to determine how many larvae can complete their development, how quickly they will develop, and what the final condition and fertility of the next generation of females will be.…”

Thrips tabaci Lind. (Thysanoptera: Thripidae) is a key pest of onions worldwide. It causes both direct and indirect damage to onion crops, resulting in high yield losses. Today, the Integrated System of Production and Plant Protection requires onion growers to use onion- thrips-resistant cultivars. It has become apparent that the improvement of existing onion cultivars may not be a sufficient, so it is necessary to search for desirable plant traits related to disease and pest resistance among existing and wild cultivars. For this purpose, we conducted bioassays on the possible preference of T. tabaci for three different cultivars of Allium cepa L., namely, Alibaba, Bila, Tęcza, one cultivar Kroll of Welsh onion, Allium fistulosum L., and the wild species Allium roylei Stearn. The settling preference and the oviposition rate of female onion thrips were evaluated using choice and no-choice laboratory tests, respectively. During the bioassay, on leaf sections of the A. roylei species, a significantly higher number of T. tabaci females was recorded compared to the cv. Tęcza of the A. cepa species and the cv. Kroll of the A. fistulosum species in each observation period. Significantly more thrips settled on cv. Kroll compared to Alibaba and Bila. Regarding the results obtained on A. cepa, significantly fewer females were found on cv. Bila compared to cv. Tęcza. Opposite results were observed in a combination of cvs. Tęcza–Alibaba, where significantly more insects settled on the leaves of cv. Alibaba. Statistically significant differences between cultivars/species were found in the number of hatched larvae on the leaves of the tested cultivars/species of onion. The lowest number of larvae hatched from eggs laid on A. roylei, as compared to A. fistulosum and the cultivars of A. cepa, except for Bila.

“…The beet armyworm, Spodoptera exigua (Hübner) (Lepidoptera: Noctuidae), is a polyphagous insect pest that can damage many plants, such as wheat, cotton, pea, cauliflower, tomato, onion, and soybean (Adamczyk et al, 2008;Saeed et al, 2010;Taylor & Riley, 2008;Zheng et al, 2000;Zhou et al, 2011). The larvae can feed on leaves and attack flowers, buds, and fruits, causing slow growth and a decrease quantity and quality of the crops (Khattab, 2013).…”

Effectiveness of Samia cynthia ricini Boisduval (Lepidoptera: Saturniidae) Cocoon Extract as UV Protectant of Bacillus thuringiensis kurstaki in Controlling Beet Armyworm Spodoptera exigua (Hübner) (Lepidoptera: Noctuidae) under Sunl

Bacillus thuringiensis (Bt) is a biological agent for insect pest management. Its toxins effectively control Spodoptera exigua Hübner (Lepidoptera: Noctuidae) larvae, but it is sensitive to ultraviolet (UV) radiation from the sunlight. This study aimed to investigate the effect of sericin extract from Samia ricini Boisduval (Lepidoptera: Saturniidae) cocoons as a UV protectant for Bt after exposure under direct sunlight for 1, 2, 3, and 4 weeks. After being exposed to sunlight, the Bt formulae were tested against 20 larvae of 24 hr old, the first larval instar in the laboratory. The larval mortality was observed 72 hr after the treatment. The results indicated that the mortality of S. exigua in Bt + sericin extract treatment was significantly different compared with Bt alone. For the first week, the mortality of S. exigua in exposed Bt + sericin exposed Bt alone, unexposed (Bt + sericin, and unexposed Bt alone were 80, 61, 85, and 97%, respectively. Scanning electron microscopy analysis revealed that Bt + sericin, after being exposed to sunlight, still showed the presence of spore and crystal protein comparable to the unexposed Bt. Based on the results, sericin provides good protection against sunlight and prevents the Bt spores from light-induced damage.
