Gynandromorphism is a phenomenon in which an individual develops with sexual mosaic of male and female traits. It is a rare phenomenon that has been reported in certain group of organisms viz., arthropods, birds, reptiles, amphibians, mammals. Gynandromorphs are expressed generally in two ways, bilateral and non-bilateral (sexual mosaics). In insects, bilateral gynandromorphs are most …

Research Notes
Researchers from IARI serendipitously discovered a gynandromorph in a lab-reared fall armyworm. Gynandromorphism is a rare phenomenon wherein both male and female characteristics are expressed (Genetically and morphologically) in an individual. Individuals expressing both male and female characteristics are called Gynandromorphs. The occurrence of such an event is very very rare (1 in 8000). One such …

Successful pest management using parasitoids requires careful evaluation of host-parasitoid interactions. Here, we report the performance of larval ecto-parasitoid wasp, Bracon brevicornis (Wesmael) on important agricultural pests, Spodoptera litura (Fabricius) and S. frugiperda (J.E. Smith). Biology of B. brevicornis was studied on different host instars under laboratory and cage setup. In no-choice assay, the parasitoid development was highest on fifth instar S. litura larvae as …

Fall armyworm Spodoptera frugiperda is an invasive alien pest that attacks mainlymaize crop. Influence of weather parameter on the incidence of S. frugiperdalarva on maize was studied during 2019-2020 at Cauvery Delta Zone, Tamilnadu,India. Random survey was conducted in six maize growing areas and correlationbetween larval population and weather parameters like maximum temperature,minimum temperature and …

Research Notes
Maize (Zea mays; Poaceae) is an important stable food (17%) and fodder crop (61%) next to rice and wheat. To study the seasonal variations and spatial distributions of fall armyworm Spodoptera frugiperda (J. E. Smith) on maize in Cauvery Delta Zone, random survey was made during 2019 -2020 at kharif and rabi seasons at six …

Research Notes
Fall army worm Spodoptera frugiperda (J. E. Smith) (Lepidoptera: Noctuidae) is one of the importantinvasive pests causing economic losses to maize, sorghum and other millets. This study aims to developsuitable cost-effective crop based artificial diet for its rearing and evaluates the biology under laboratoryconditions. Study revealed that the least life cycle period (egg to adult) …
