The geometrid Apocheima sp.is one of the worst pest of the locust tree in Mei County.It apparently prefers the locust tree,but also devastates the near-by apple and pear trees.This paper reports the results of our studies on the bionomics and control measures of this insect from 1971 to 1974.This insect has only one generation a year in Shensi Province and overwinters.as a pupa encased in a thick cocoon under the ground.The adult emerges in late February the next year and lays eggs on the top of the locust tree.Larvae hatch in early April and they have the habit of spinning silk threads hanging down from the tree and spreading to another tree by wind.The full-grown larvae move downward to dig into the ground in late May and after 40 days of pre-pupal stage they pupate under ground in thick cocoons in late July.The results of our study show that the most effective control measure is to dust BHC over the ground surface at the beginning of emerging stage of the adults.

刺槐尺蠖是陕西省眉县地区刺槐林的主要害虫。经初步调查,其寄主植物包括林木、农作物和果树等34种,其中刺槐、苹果和梨受害最重。该虫一年发生一代,以结茧蛹在土中过冬。翌年2月下旬开始羽化,3月中旬至4月上旬为盛期,末期于4月中旬。成虫雌雄异型。雄蛾有翅善飞,有趋光性。雌蛾无翅,仅能缓慢爬行。雌蛾一般羽化、交尾和产卵一日内完成。卵多产于一年生枝梢端部阴面,卵粒排列成行,数行或数十行成一卵块,卵块平均有卵462粒。初孵幼虫有吐丝下垂、随风飘荡扩散的习性。幼虫为害期在4月上旬至5月上旬,老熟幼虫于5月中旬开始下树。 根据此虫生物学特性,以地面喷、撒六六六粉消灭成虫效果最好,幼虫幼龄阶段实行树上喷六六六粉也是可行的防治措施。

Lampra limbata Gebler is a destructive insect species of pear trees. Its larva and pupa stage is closely related to temperature.This stage begins in the third decade of April, and flourishes in the second decade of May, and finishes in the third decade of June. Hot and wet wheather is good for eclosion of its adults; and rain fall has much to do with their action.The adult stage begins in the second decade of May,flourishes in the third decade of the same month,and finishes in the second decade of June....

Lampra limbata Gebler is a destructive insect species of pear trees. Its larva and pupa stage is closely related to temperature.This stage begins in the third decade of April, and flourishes in the second decade of May, and finishes in the third decade of June. Hot and wet wheather is good for eclosion of its adults; and rain fall has much to do with their action.The adult stage begins in the second decade of May,flourishes in the third decade of the same month,and finishes in the second decade of June. The adult has a habit of pretending to be dead; and the life-span of the male adults is shorter than that of the female ones.It is in this stage that the insects do damage to pear and black locust trees. The population density of female iasects is 7.9-12.9 times higher than that of male ones.The better the tree grows,the less the trees suffers from the pest. The measures, spraying insecticide over the trees and collecting abult insects in adult period fumigating trunks or daubing their damaged parts with insecticide in larva period and improving the tree management,can all be used to control the pest effectively.

金缘吉丁虫是梨树的毁灭性蛀干害虫。虫蛹发生期主要与温度相关,4月下旬为始期,5月中旬为盛期,6月初为末期;成虫羽化喜温暖、高湿天气,与降雨关系密切,5月中旬为始期,5月下旬为盛期,6月中旬为末期;成虫具假死性,雄成虫寿命比雌成虫短;为害梨树和死刺槐,后者比前者虫口密度高7.9~12.9倍;梨树树势越强,受害越低,反之就高。成虫期树上喷药、捕捉成虫,幼虫期药剂熏蒸主干、涂刷虫部枝干以及加强管理、增强树势等措施,均能取得良好的防治效果。

This paper reports a research result of technology development system of fuel forest resources at the places where are both lower level hills and arid areas. Retaining the natural precipitation with the special filling and soil preparation technologies, the survival rate of afforestation on barren mountains can reach 93.4%. Adopting an artificial promotion technology and brushwood production method to transform low output locust trees, the quantity of overground organisms can increase 21.5% and 69.1% respectively....

This paper reports a research result of technology development system of fuel forest resources at the places where are both lower level hills and arid areas. Retaining the natural precipitation with the special filling and soil preparation technologies, the survival rate of afforestation on barren mountains can reach 93.4%. Adopting an artificial promotion technology and brushwood production method to transform low output locust trees, the quantity of overground organisms can increase 21.5% and 69.1% respectively. Transforming Chinese pine forest on a hill into the mixed forest, the annual forest output can be obtained 190 kg/mu Planting mixedly sallow thorns, a nitrogen-fixing bush, among the rows of poplars on the flood land, the annual forest output can be obtained 325 kg / mu. Topdressing phosphate fertilizer, the organic quantity of three-year locust can increase 29.8%. Using an artificial inoculation against nodule bacteria or both of nodule bacteria and vaccine, the organic quantity of young locust can increase 29.8 -48.6%.

本文报道了我国北方低山丘陵易旱区薪材资源开发技术体系的研究结果。采用水平槽回填土工程整地技术,可拦蓄天然降水,使荒山造林成活率达到93.4%;采用人工断根促萌技术和实施矮林作业经营方式改造低产刺槐林,可分别增加地上部生物量21.5%和69.1%;改造山地油松纯林为复层混交林,可获薪材190kg/(亩·年);在河滩地杨树用材纯林行间混栽固氮灌木——沙棘,可获薪材325kg/(亩·年);追施磷肥可使三年生刺槐薪炭林生物量增加29.8%;实施人工接种根瘤菌及根瘤菌与菌根菌(VA)联合接种技术,可使刺槐幼林生物量增加29.8~48.6%。
