扑灭实蝇之战

前言日本奄美、冲蝇的西南诸岛上发生柑桔小突蝇和瓜实蝇;小笠原诸岛上发生了柑桔小实蝇。这些地区实蝇寄主上的鲜果实等禁止向日本本土末发生的地区携带。实蝇的发生,已成为这两诸岛上农业振兴的大障碍,因此扑灭实蝇乃是发生地区农业从业人员的长期梦想。日本农林水产省为了捕灭实蝇,制定了防除计划,根据这个计划,从1968年开始,在奄美群岛的喜界岛采用诱杀雄虫的方法扑灭柑桔小实蝇;从1974年开始,在久米岛上采取饲养释放雄性不育虫的方法,来扑灭瓜

Field performance of Lynfield and McPhail traps for monitoring male and female sterile Bactrocera tryoni (Froggatt) and wild Dacus newmani (Perkins)

BACKGROUND: McPhail traps, baited with protein food lure, are used worldwide for surveillance of many species of fruit flies. Queensland fruit fly (Qfly) Bactrocera tryoni (Froggatt) (Diptera: Tephritidae) is a native Australian fruit fly and normally monitored using Lynfield traps baited with cuelure. On some occasions, McPhail traps with wet food lures are deployed to detect female flies or to find the incursion epicentre. This paper reviews field results on the merits of Lynfield and McPhail traps for detection of male and female Qfly. RESULTS: Following release of equal numbers of sterile males and females, Lynfield traps baited with cuelure captured more Qfly males than protein autolysate or orange concentrate in McPhail traps. Significantly more male than female Qfly were captured in McPhail traps baited with protein autolysate or orange. There was no significant difference between orange concentrate lure and protein autolysate lure in attracting either males or females. Another Australian native fruit fly, Dacus newmani (Perkins), was attracted to cuelure in Lynfield traps but not to either lure in McPhail traps. CONCLUSIONS: The data obtained run counter to the reputation of McPhail traps baited with protein autolysate or orange concentrate as a specialist lure/trap combination for female Qfly.

Aerial Application of Chemicals at Low and Ultra-low Volume Against Main Pests of Citrus and Olive Trees in Tunisia and Libya

Encouraging results were obtained in low and ultra-low volume aerial applications against Ceratitis capitata Wied. in Tunisia (Malathion LV 96%) and against this pest and against Dacus oleae Gmel. in Libya (with Malathion LV, phosphamidon 50 and 100% a.i. and dicrotophos 100%). The mixture rates of insecticide and bait were also considered.

Report on Olive Fly Control with Ultra-low Volume Concentrate Bait Air Sprays

In the 1968 olive fly control season the effectiveness of an ultra-low volume concentrate bait consisting of 87% protein hydrolysate and 13% insecticide Malathion ULV 96% and of a standard type bait, consisting of 12% protein hydrolysate Atropaz, 1,57% malathion 57% (0.9% active ingredient) and 86.43% water, applied by air against the Dacus fly were compared. Both baits resulted in very good olive fly control and the olive fruit at the end of the season was completely free of any infestation. No differences in the effectiveness of the two baits tried could be established, however.

The Use of Cidial and Rogor Formulations in Ultra-low Volume Treatments from Helicopters

When various technical problems connected with ULV spraying from helicopters had been solved the practical application of insecticides was started. Rogor L 30 (dimethoate) was successfully used against Dacus oleae Gmel. and Cidial 50 L (phenthoate) against mosquitoes. The results of the use of Cidial against Thaumetopoea pityocampa Schiff. are being analysed, and the possibilities of applying fungicides at ULV rates in vineyards and on poplars, tobacco and beet crops are being investigated.

饲喂吖啶橙对玉米螟赤眼蜂生物学的影响及标记效果

吖啶橙是一种可对昆虫进行标记的染料。本文通过饲喂,考察了吖啶橙对玉米螟赤眼蜂的寿命、产卵量及子代发育情况的影响。结果发现,饲喂吖啶橙延长了蜂的寿命,雌蜂寿命从对照的4.8d显著延长到饲喂低浓度吖啶橙的5.7d,而雄蜂的寿命以饲喂20mg/L吖啶橙的最长,为5.5d。饲喂5和10mg/L吖啶橙溶液的雌蜂6h内的产卵量分别为29.9和30.1粒,略低于对照的34.9粒,饲喂20mg/L的为35.1粒,但各处理与对照间产卵量无显著差异。饲喂吖啶橙对蜂的寄生率、子代羽化率及子代数量均有负面影响。饲喂10mg/L吖啶橙的蜂的寄生率为73.67%,显著低于对照87.83%;饲喂5mg/L吖啶橙的蜂的子代羽化率为96.46%,显著低于对照的99.50%。饲喂5和10mg/L吖啶橙的玉米螟赤眼蜂子代数量分别为(17.1±0.8)和(17.1±1.2)头,显著低于对照的(21.4±0.7)头,饲喂吖啶橙对子代雌性比无显著影响。饲喂吖啶橙24h后,在荧光显微镜下可以观察到吖啶橙的荧光,但由于蜂具有自发荧光,部分饲喂过吖啶橙的蜂不能完全区别于未饲喂的个体。综合考虑吖啶橙对玉米螟赤眼蜂寿命、产卵量和寄生能力的影响以及标记效果,应对吖啶橙进行修饰,或改变观察的理化条件,消除生物自发荧光的干扰,然后用于对赤眼蜂的标记。     

Detection and characterization of <Emphasis Type="Italic">Citrus tristeza virus</Emphasis> stem pitting isolates in Jamaica

An island wide survey for Citrus tristeza virus (CTV) in citrus orchards across Jamaica (13 regions) was conducted over 2 years. Trees (1, 885) showing virus-like symptoms as well as asymptomatic trees were randomly sampled for testing by ELISA and 55 samples from the 6 major citrus growing regions were graft inoculated on indicator plants. Most samples (74%) reacted to polyclonal antibodies against CTV in ELISA, while 20% were positive in tests using monoclonal antibodies specific to severe CTV strains. Samples collected from the 6 major citrus growing regions produced vein clearing and stem pitting symptoms on Mexican lime indicator plants (87%). In addition, stem pitting symptoms were induced on Duncan grapefruit, sweet orange, sour orange or sweet orange grafted on sour orange. Nucleotide sequencing of the coat protein gene sequences isolated from these samples indicated high identities (88 to 95.5%) among the Jamaican isolates and previously reported stem pitting strains from Central and North America and Eurasia (88 to 100%). The results suggest a shared ancestry with isolates from other geographical locations, rather than geographical speciation, and presumably separate CTV introductions into Jamaica.
