Pests
Chrysanthemum indicum L.
Thrips infestation on Chrysanthemum indicum manifests as deformation of buds and leaves, the appearance of silvery streaks, and the presence of pest excrement. The main pest species for this crop are Frankliniella occidentalis, Thrips tabaci, Thrips nigropilosus, and Thrips parvispinus.
In the reference 3 varieties crop Indian chrysanthemum, where this is mentioned in the description.
A number of species of the order Thysanoptera have been recorded on Chrysanthemum indicum, among which the western flower thrips is the most significant for commercial plantings. The crop is also infested by the onion thrips, chrysanthemum thrips, and other representatives that cause damage to vegetative and generative organs.
External signs of damage include the appearance of light streaks, spots, and 'scars' on leaf blades, their yellowing and deformation, as well as stunted and discolored flowers. The presence of black excrement on the leaf surface is a characteristic indicator of insect activity, leading to a slowdown in the overall growth of the plant.
Specific resistance genes to thrips in Chrysanthemum indicum have not been described at present. Despite the proven genetic variability of cultivars in terms of susceptibility, reliable resistance to pests remains a subject of active study, while sources of breeding material continue to be sought among wild relatives of the genus Chrysanthemum.
