The major quarantine pests identified recently on cut flowers include bollworms (Helicoverpa armigera, Spodoptera spp.), leaf miner (Liriomyza sp.), white flies (mainly Bemisia tabaci), thrips (mainly western flower thrips – Frankliniella spp.), and fruit flies (Otieno, unpubl.). The greenhouse provides a modified environment which, in many ways, favours the proliferation of cut flower pests and diseases. During certain times of the year, day temperatures in the greenhouse may soar upto 26° -33°C which reduces the regeneration cycle for many pests.
