Anastrepha grandis (Macquart) (Diptera: Tephritidae) is endemic to the lowland Andean region of South America and considered a quarantine pest of cucurbits by most tropical and subtropical countries outside of the infested region.
LIKE all cucurbit seeds, courgette seeds are a flat oval shape and should normally be sown in a heated environment in mid-late April, ready for planting outdoors in early June.
In Pakistan, various economically important cucurbit crops are produced annually during summer, and of these, watermelon assumes to be highly significant with enriched protein, carotenoids and lycopean with an antioxidant potential (Edwards et al., 2003; Melger et al., 2008).
Area growers and other experts say recent steady rains have left some pumpkin vines, as well as other species of the Cucurbit family, covered in powdery mildew.
Wayadande is using the monitor to study how squash bugs transmit Serratia marcescens, the bacterium that causes cucurbit yellow vine disease, to watermelon and other cucurbits.
