Data in presence of live insects at field prototype conditions: (a) Sensing of pheromones by the functionalized devices in a box with eight of the female insects. Selectivity of the devices from the kairomones of (b) tomato seedlings and (c) tomato plants is represented. A mimic of the field condition with six of the tomato plants and four of each male and female insect is shown in (d). Schematic representation for the detection of female sex pheromone of Helicoverpa armigera, Scirphophaga incertulas and the like pests, prior infestation, by the use of covalently functionalized MEMS devices is demonstrated in (e).
