Table 4. The mean area (mm2) of 10-week old H. lataniae adult armoured caps from insects settling on the stems, petioles and leaf nodes of potted A. deliciosa ‘Hayward’ plants subjected to three Acibenzolar-s-methyl (ASM) sprays and Psuedomonas syringae pathovar actinidiae (Psa) inoculation compared with those on untreated control plants.
Sample sizes in brackets. The mean size of the insects on ASM-treated plants was significantly smaller than the insects on control plants (Dunnett’s test with family error rate of 5%), but insects on Psa-treated plants were not different from those on stems of control plants.
