[Roles of olfaction and vision in orientation behavior of adult Campylomma chinensis Schuh (Hemiptera: Miridae) toward Lantana plants (Verbanaceae)].
Investigations were carried out on the orientation behavior of adult Campylomma chinensis Schuh (Hemiptera: Miridae) toward plant hosts Lantana camara, L. caniara cv. 'Flava', and L. montevidensis (Spreng. ) Briq. (Verbanaceae). Surveys on three Lantana plants showed that the distribution of C. chinensis in inflorescences was not related to floral color (partial correlation coefficient was 0.240, P = 0. 147, n = 40), but to the number of Thrips hawiiensis Morgan (partial correlation coefficient was 0.512, P < 0.0001, n = 40) and the flowers per inflorescence (partial correlation coefficient was 0.451, P < 0.0001, n = 40). In a colour preference experiment, no adult C. chinensis attracted to six different colour plates in longan field. The testing results of four-armed olfactometer indicated that adult C. chinensis had a significantly higher preference for L. camara. It was concluded that olfactory stimuli played an important role in searching for plant hosts of C. chinensis. Solid phase microextraction (SPME) and GC-MS were employed to analyze the volatiles compounds of Lantana, and seven same chemical constituents were detected from the volatiles of three Lantana plants inflorescence.
