Growth inhibition of Spodoptera frugiperda larvae by camptothecin correlates with alteration of the structures and gene expression profiles of the midgut

Abstract: Background Spodoptera frugiperda is a serious pest that causes devastating losses to many major crops, including corn, rice, sugarcane, and peanut. Camptothecin (CPT) is a bioactive secondary metabolite of the woody plant Camptotheca acuminata, which has shown high toxicity to various pests. However, the effect of CPT against S. frugiperda remains unknown. Results In this study, bioassays have been conducted on the growth inhibition of CPT on S. fr… Show more

“…The laboratory population had been established without pesticide exposure for more than two years. The larvae were maintained with an artificial diet, and the recipe for a 1 kg diet contained 100 g corn flour, 80 g soy flour, 26 g yeast powder, 26 g agar, 8.0 g vitamin C, 2.0 g sorbic acid, 1.0 g choline chloride, 0.2 g inositol, and 0.2 g cholesterol 58 . The adults were fed with 10% honey water.…”

“…Among these were genes encoding detoxification-related proteins and components of the peritrophic membrane such as mucins and cuticle proteins. Pathway enrichment analyses indicated these DEGs were involved in DNA replication, digestion, immunity, endocrine system and metabolism [ 133 ].…”

“…Damage to the digestive organs can inhibit the food absorption process, so the larvae's energy needs are not fulfilled. As a result of this lack of energy, it can inhibit the process of larval development Changes in the digestive organs of Fall armyworms have an impact on larval development, interfere with the functioning of the digestive system, and disrupt the larval metabolic system [22].…”
