辽宁三种林业害螨生物学特性研究初报 总被引：1，自引：0，他引：1
本文报道了三种林业害螨，即棒毛小爪螨，柏小爪螨，云杉小爪螨的生物学特性。上述三种害螨均属蜱螨目叶螨科，是为害针叶树人工林的主要害螨之一。近年来在辽宁很多地区的油松、赤松、樟子松、落叶松人工林中大量发生，城市绿化的柏树也受到为害，造成针叶枯黄脱落，影响林木生长。三种害螨每年发生７￣９代不等，均以卵在树皮缝，芽鳞，果鳞等处越冬，适时采用４０％氧化乐果，５０％二溴磷乳剂或８０％敌敌畏喷洒，均可收到较好的 相似文献

A survey of insect pests of stored products in three main regions of Saudi Arabia was carried out during two successive years, 1978 und 1979. Randomized samples of different commodities were collected for inspection from 13 localities four times a year. Thirty six species of insect pests belonging to 12 families and 4 orders in addition to 2 hymenopterous parasites were recorded. 相似文献

From January 2001 to December 2004, the investigation on the species of insect pests and diseases in Torreya grandis Merrillii was conducted and integrated control technologies of the main insect pests and diseases were studied in Zhuji,
Shaoxin, Shenzhou, Dongyang, and Jiande counties of Zhejiang Province. Via field survey, a system of regular observations,
55 species of insect pests belonging to 9 orders and 29 families, and 4 species of diseases were recorded. Among them, Lepteucosma torreyae and Macrolygus torreyae were found to be new species. The biological characteristics of the major insect pests and diseases, such as Rhyncaphytoptus abiesis, Helicobasidium compacum, Erwinia carotovora, Chlorella sp., Macrolygus torreyae, and Lepteucosma torreyae, were primarily recorded, and their outbreaks and epidemics were researched. The forecasting method for Lepteucosma torreyae was established. Based on strengthening cultivation and management, integrated control measures were put forward including
physical, biologic and chemical methods. Medications with higher effect and lower toxicity were screened by comparing the
effect of different pesticide treatments.

2015年3月—2016年6月,每个月定期对杨叶肖槿（Thespesia populnea）虫害进行调查。结果表明,杨叶肖槿栽培过程中害虫种类主要有7种,隶属5目7科。其中棉卷叶野螟（Sylepta derogate）、瘤缘蝽（Acanthocoris scaber）和八点广翅蜡蝉（Ricania speculum）最常发生且为害最严重。在栽培过程中,可采取如下防治措施：（1）棉卷叶野螟可利用黑光灯诱杀成虫,在产卵盛期至卵孵化盛期喷菊酯类杀虫剂;（2）瘤缘蝽的防治应及时清除枯枝落叶及林边杂草,摘除有卵的叶片,在若虫孵化盛期选择高效、低毒、低残留农药施药;（3）八点广翅蜡蝉可采用化学药剂进行防治,也可悬挂诱虫灯诱杀成虫。 相似文献
