| 中文摘要: |
| 为弄清澳洲坚果园斑点广翅蜡蝉的发生为害规律及对不同品种枝的产卵趋性，采用五点取样法调查该虫种群消长规律、成虫产卵对澳洲坚果枝的为害情况及对不同品种枝的产卵嗜好。结果表明，在南宁该虫1年发生1代，以卵越冬，3月中旬若虫开始孵化，4月上旬至5月中旬为若虫盛发期；4月下旬始见成虫，5月中旬至6月上旬为成虫盛发期。雌成虫偏好在直径为2.00~2.99 mm，距芽梢6.00~30.00 mm的新梢上产卵。枝条着卵量与产卵刻痕长度、产卵排数均极显著正相关；受害枝条直径与产卵排数显著正相关，与同梢产卵刻痕数量显著负相关。雌成虫对桂热1号和HASE695新梢均具有很高产卵偏好，且均显著高于A16和JW。因此，3月中下旬和4月中下旬是防治该虫若虫和成虫的关键时期；剪除距芽梢约30.00 mm，直径为2.00~2.99 mm受为害较重的枝条，可有效降低越冬虫源。 |

| In order to understand the occurrence and damage regularity of R. guttata in macadamia nut orchard and its oviposition preference to branches of different varieties, the five-point sampling method was used to investigate the population dynamics, the damage of oviposition on macadamia branches and the oviposition preference of different varieties of macadamia branches. The results showed that R. guttata completed one generation per year in macadamia orchards of Nanning and overwinter with eggs. The nymph hatched in mid-march, the peak period of nymph was from early April to mid-May. The adult was emergence late April, the peak period of the adult was from mid-may to early June. Female adults prefer to lay eggs on new shoots with a diameter of 2.00~2.99 mm and a distance of 6.00~30.00 mm from buds. There was a significant positive correlation between the number of eggs laid on branches and the length of oviposition scar and the row number of oviposition. The diameter of injured branch was positively correlated with the row number of oviposition and negatively correlated with the number of oviposition scars on the same branch. The female adult had high oviposition preference for the shoots of Gui re No.1 and HASE695, which was significantly higher than that of A16 and JW. Therefore, the critical period of controlling nymphs and adults is mid-late march and mid-late April. It is effective to reduce the overwintering insect source by cutting off the seriously damaged branches about 30.00 mm from bud tip and 2.00~2.99 mm in diameter. |
