Pine wilt is a serious and fatal disease in pine forests. It is caused by the pine wood nematode, Bursaphelenchus xylophilus, transmitted by the Japanese saw beetle Monochamus alternatus. Control of this disease depends on reducing its vector population. The public is demanding environmentally friendly control methods and biological control has become increasingly seen as an important, safe and effective approach. Through our investigations both in the field and by breeding in our laboratory, a new predator of M. alternatus, Tetrigus lewisi (Coleoptera: Elateridae), was found for the first time in China. Given our continuous observations, we are assured that the predatory behavior of the elater can be separated into four parts, i.e., foraging and sensing, killing, eating and excretion. They always took several hours to eat the preys that have been killed momentarily. We finally found that most of the elaters preferably attacked in the stomach and abdomen of the larva of M. alternatus.

Brain asymmetry for processing visual information is widespread in ***,it is still unknown how the complexity of the underlying neural network activities represents this asymmetrical pattern in the *** the present study,we investigated this complexity using the approximate entropy(ApEn)protocol for electroencephalogram(EEG)recordings from the forebrain and midbrain while the music frogs(Nidirana daunchina)attacked prey *** results showed that(1)more significant prey responses were evoked by the prey stimulus presented in the right visual field than that in the left visual field,consistent with the idea that right-eye preferences for predatory behaviors exist in animals including anurans;(2)in general,the ApEn value of the left hemisphere(especially the left mesencephalon)was greatest under various stimulus conditions,suggesting that visual lateralization could be reflected by the dynamics of underlying neural network activities and that the stable left-hemisphere dominance of EEG ApEn may play an important role in maintaining this brain asymmetry.
