The fall armyworm (FAW), Spodoptera frugiperda (J. E. Smith) (Lepidoptera: Noctuidae), has become a major threat in maize cultivation since its invasion to India in 2018. The humpbacked fly, Megaselia scalaris (Loew) (Diptera: Phoridae), was recorded as a laboratory parasitoid of FAW, for the first time in India. Initially, 30–40 maggots of M. (M) scalaris emerged out from the dead pre-pupa and pupa of laboratory-reared FAW. The fly laid up to 15 eggs on the outer surface of 6th instar larva or pre-pupa of the FAW. The incubation period was 1–2 days. The fly had 3 larval instars which lasted 3–4 days and a pupal period of 10–11 days. The adults survived for 6–7 days.

来自印度的秋季粘虫，草地贪夜蛾（JE Smith）（鳞翅目：夜蛾科）的寄生蜂，Megaselia（M）scalaris（双翅目：Phoridae）的第一个记录

秋季粘虫（FAW）草地贪夜蛾（JE Smith）（鳞翅目：夜蛾科）自 2018 年入侵印度以来已成为玉米种植的主要威胁。 驼背蝇 Megaselia scalaris（Loew）（双翅目：Phoridae），在印度首次被记录为一汽的实验室寄生虫。最初，30-40 只 M. (M) scalaris 蛆从实验室饲养的秋粘虫的死前蛹和蛹中出现。苍蝇在 6 龄幼虫或一汽前蛹的外表面上产下多达 15 个卵。潜伏期为1-2天。苍蝇有3个幼虫龄期，持续3-4天，蛹期为10-11天。成虫存活6-7天。
