The tomato leaf miner, Tuta absoluta (Meyrick), is the most important pest for tomato production in Iran. The effect of flubendiamide and thiocyclam hydrogen oxalate insecticides was assessed on cellular energy allocation (CEA) of the third instar larvae of T. absoluta ingesting six different tomato cultivars. Plant leaves were treated with LC₅₀ concentration of both insecticides and their energy available (E_a), energy consumption (E_c), and CEA were calculated. The results showed that total energy reserves (protein, carbohydrate, and lipid budgets) were significantly reduced after exposure to insecticides and tomato secondary metabolites. The larvae fed on Riogrande and Super Chief cultivars showed the least amount of energy available after treatment with both insecticides. The highest rate of oxygen consumption was observed in larvae fed on Calj, Super Luna, and Super strain B after treatment with flubendiamide. The amount of CEA decreased in treated larvae compared to untreated larvae. This reduction was statistically higher in treated larvae that fed on Riogrande and Super strain B cultivars. Reduction in CEA is probably due to the expenses of dealing with detoxification of insecticides and plant metabolites. CEA is a suitable and primary biomarker for the effects of cultivars and insecticides as integrate and summarizes insect energy allocation in variable situations.

番茄潜叶虫Tuta absoluta (Meyrick) 是伊朗番茄生产中最重要的害虫。评估了氟虫双酰胺和硫环菌素草酸氢杀虫剂对T. absoluta三龄幼虫摄取六种不同番茄品种的细胞能量分配 (CEA) 的影响。用 LC ₅₀浓度的杀虫剂及其可用能量 (E _a )、能量消耗 (E _c)，并计算 CEA。结果表明，暴露于杀虫剂和番茄次生代谢物后，总能量储备（蛋白质、碳水化合物和脂质预算）显着减少。以 Riogrande 和 Super Chief 品种为食的幼虫在用两种杀虫剂处理后表现出的能量最少。在用氟虫双酰胺处理后，在以 Calj、Super Luna 和 Super 菌株 B 为食的幼虫中观察到最高的耗氧率。与未经处理的幼虫相比，经处理的幼虫中 CEA 的量减少。在以 Riogrande 和 Super B 品种为食的处理过的幼虫中，这种减少在统计学上更高。CEA 的减少可能是由于处理杀虫剂和植物代谢物的解毒费用。
