Tsetse flies transmit trypanosomes that cause nagana in cattle, and sleeping sickness in humans. Therefore, optimising visual baits to control tsetse is an important priority. Tsetse are intercepted at visual baits due to their initial attraction to the bait, and their subsequent contact with it due to landing or accidental collision. Attraction is proposed to be driven in part by a chromatic m...

A better understanding of the visual attraction of house ßies to colors and patterns is needed to improve ßy trap performance. This study combined physiological responsesmeasuredwith electroretinogram studies of the house ßyÕs compound eyes and ocelli with behavioral attraction of ßies to reßective colors and patterns in light tunnel assays. Compound eye and ocellar electroretinogram responses ...

When a target is presented near a leading cue stimulus, the perceived location of the target is displaced from the cue (attentional repulsion). On the other hand, a memorized target is sometimes mislocalized toward the cue (attentional attraction). The present study aimed at clarifying the temporal relationship between attentional repulsion and attentional attraction. We used a relative judgmen...

The Asian citrus psyllid, Diaphorina citri, vectors huanglongbing (HLB), the most serious disease affecting citrus globally. D. citri and HLB have spread to the major citrus growing regions of North America causing billions of dollars of damage in Florida alone. The visual behavior of D. citri is not well characterized and more knowledge is needed to improve attractive traps for monitoring and ...

BACKGROUND For a fruit fly, locating fermenting fruit where it can feed, find mates, and lay eggs is an essential and difficult task requiring the integration of olfactory and visual cues. Here, we develop an approach to correlate flies' free-flight behavior with their olfactory experience under different wind and visual conditions, yielding new insight into plume tracking based on over 70 hr o...

Our branch predictor proposed for the Championship Branch Prediction (CBP) contest is a hybrid/mutation of many different ideas previously proposed in the literature, combined with a few new techniques. The mix of traces requires the predictor to handle both capacity (large tables) and deep correlation extraction (long branch histories), both made difficult by the relatively small hardware budg...
