Diel Behavioral Activity Patterns in Adult Solitarious Desert Locust, Schistocerca gregaria (Forskål)

Table 2

Comparison of the distance traversed and numbers that reached the host plant (Heliotropium sp.) stimulus in photophase and scotophase. 𝑁 = 80 insects used for each of the three behaviors.

x Means with the same superscript letter are not significantly different (LSD test, 𝑃 < . 0 5 ).
y Difference between photophase and scotophase activity for each sex in a group of locusts: significant at 𝑃 < . 0 5 ( 𝑡 -test).
