    Evaluation of cinnamic aldehyde as antifeedant against lesser bandicoot rat, Bandicota bengalensis
    (Punjab Agricultural University, Ludhiana, 2014) Ajooni; Babbar, B.K.
    Four different concentrations of cinnamic aldehyde (1, 2.5, 5, 7.5%) were tested against bandicoot rat Bandicota bengalensis in bi-choice feeding tests. Results revealed that 5% cinnamic aldehyde treated bait has an antifeedant/secondary repellent effect against B. bengalensis which retained both at a gap of 7 (treatment period 2) and 14 (treatment period 3) days of treatment. Rats were not habituated to effective concentration of cinnamic aldehyde upto experimental period of 27 days. There was a non-significant difference between average consumption of untreated and treated bait during first two hours indicating absence of primary repellent effect of cinnamic aldehyde in both the sexes under bi-choice conditions. Formulation II containing 5% cinnamic aldehyde, 1% sodium bicarbonate as emulsifier and 1% tert-butyl hydroxyquionone as photostabilizer prevented rodent damage upto 14 days in summer squash, 12 days in tomato and also reduces the damage in black mash upto 16 days indicating that photostabilizer present in formulation prevented photodegradation of cinnamic aldehyde and thus increased effectiveness of cinnamic aldehyde to prevent rodent attack to field crops. Whereas formulations I and (III-X) could not prevent the damage caused by the rodents. Study of rat behavior in I-maze under Ethovision Video Tracking System confirmed the absence of primary repellent effect and study of feeding behavior in Food Scale Consumption Monitor (FSCM) confirmed the existence of secondary repellent/ antifeedant effect of cinnamic aldehyde against bandicoot rat B.bengalensis.
