abstract
Study on food selection in two grasshopper species i-e:namely Calliptamus barbarus (Costa, 1836). and Chorthippus biguttulus (Linnaeus, 1758) was carried out during the year 2016 from Pakistan. Specimens were collected and kept in jars in order to note their feeding behavior. In addition to this, survival rate of species on different host plants was observed. The survival rate of C. barbarus was observed as 4.11 ± 4.67 followed by C. biguttulus as 17 ± 4.38 on Cynodon dactylon, Paspalum notatum and Psidium guajava respectively. Furthermore, it was found that insects did not preferred Brassica oleracea var. capitata. The present study findings will be very helpful to future researchers concerned with rearing of C. barbarus and C. biguttulus
