Foraging bias benefits increased with increasing plant size and decreasing aphid density. It may be beneficial for individuals in highly complex branched environments to have a turning bias slightly lower than 100% in order to benefit from increased foraging efficiency without walking in circles. In general the benefits to foraging of implementing a turning bias increased with the degree of the bias.
COCCINELLA SEPTUMPUNCTATA PATCH
A modification of the model to investigate foraging efficiency, by calculating the mean time taken by individuals to find randomly distributed aphid patches, suggested that on four different sizes of plants, with a variety of aphid patch densities, implementing a turning bias was a significantly more efficient foraging strategy than no bias. septempunctata in dichotomous branched environments showed that model coccinellids with greater turning biases discovered a higher proportion of the plant for a given number of searches than those with no bias. A model of the searching efficiency of C.
In the maze right-handed individuals turned right at 84.4% of turns and the left-handed individuals turned left at 80.2% of turns. Approximately 45% of all individuals tested displayed significant turning biases, with a similar number of individuals biased to the left and right. Individuals were placed repeatedly in the maze. would exhibit a turning bias when walking along a branched linear wire in a Y-maze was tested.
