Pollination and gene flow in chillies with Scirtothrips dorsalis as pollen vectors

The time of production of viable pollen, stigmatic exudates and nectar, alongwith the prevailing environmental conditions, play an important role in attracting the thrips to the chilly flowers for food. Foraging activities of thrips within the same flower cause self-pollination. Larger populations of thrips creates competition for food, leading to their migration to other flowers and thus ensure cross-pollination. Scirtothrips dorsalis Hood especially helps in pollen transfer between two varieties of chillies, namely, Capsicum annuum L. var. Pusa Jwala with solitary and C. frutescens L. var. Pusa Sadabahar with clustered fruits. [AS]
