Abstract:

Objective To examine the effect of Masson pine pollen and Zea pollinium as food attractant to Reticulitermes chinensis. Methods The treatments were designed with Masson pine pollen, and Zea pollinium at 5%, 10%, 15%, 20%, 25%, and 30%. The olfactory response and selectivity of R. chinensis were determined with a four-arm olfactometer, and food consumption of during 10 d was measured. Results The results showed that 15% and 25% Masson pine pollen, and 5%, 10%, and 15% Zea pollinium had a repellency to R. chinensis, but other concentrations with an attractant effect; food consumption of R. chinensis to untreated control(52-54 mg)was significantly more than the baits containing Masson pine pollen(5-24 mg); between untreated control(11-57 mg)and 5%, 10%, 15%, 20%, and 25% Zea pollinium(15-43 mg), there was no significant difference,but significant at 30% Zea pollinium(108 mg)obviously more than to control check (12 mg). Conclusion 20% Masson pine pollen and 15% Zea pollinium were attractive to R. chinensis. Termite didn't like food containing Masson pine pollen, but preferred food containing Zea pollinium and food consumption gradually increased with concentration increasing. Therefore, researchers suggested that olfactory response and food consumption had no correspondence, and should research and analyze separately.
