Flexible use of patch marks in an insect predator: effect of sex, hunger state, and patch quality OAK
Nakashima, Yoshitaka; Teshiba, Mayumi; Hirose, Yoshimi; 仲島, 義貴.
1. Patch marks that allow the subsequent avoidance of marked areas may be used by small animals to increase foraging efficiency. This study is the first to demonstrate the presence of a patch-marking system in insect predators. Furthermore, the marking system is found only in females, and factors such as hunger state and patch quality play a key role in determining whether a female will re-investigate a self-marked patch. 2. Females of the insect predator Orius sauteri avoided areas where the female itself had searched previously but did not avoid areas searched by conspecific females when deprived of prey for 24 h. There was no evidence that males use such a patch-marking system, indicating the presence of a sex difference in patch-mark use. 3. Females...

Sex differences in foraging behaviour and oviposition site preference in an insect predator, Orius sauteri OAK
Nakashima, Yoshitaka; Hirose, Yoshimi; 仲島, 義貴.
The effects of patch quality on the foraging behaviour of an anthocorid predator Orius sauteri (Poppius) were compared between sexes. Prior experience in patches was also studied to determine whether this was a factor affecting oviposition decisions. Patch quality affected patch residence time differently for the two sexes; females stayed much longer in a patch with prey (60 Thrips palmi larvae) than a patch without prey, while males did not remain in any patch for extended periods. Most of the females remained in or moved to patches with prey, whereas males dispersed, irrespective of patch quality. Both females released in patches with prey and females released in patches without prey deposited more eggs per hour in patches with prey than in patches...
