华北大黑鳃金龟成虫周年发生动态及影响因素分析

华北大黑鳃金龟[Holotrichia oblita(Faldermann)]是一种为害多种作物的重要地下害虫,为了解其近年的发生动态以便针对性防治,于2010-2013年对其成虫出土规律进行了周年系统研究,并对其发生期和发生量影响因素进行了初步分析。结果表明,2010-2013年华北大黑鳃金龟的出土盛期仍在5月份,与文献相比总体一致,但出土期略滞后并且时间有所延长;而2013年始发期明显晚于其他年份,对其气象因素分析发现,2013年春季干旱,首次降雨在5月26日,明显晚于其他年份,其始发期也较其他年份偏晚,说明土壤湿度可能影响成虫出土始期。出土盛期成虫出土量与气象因素的灰色关联度分析表明,成虫日出土量与平均相对湿度关联最密切,其次是日均温和降雨量。研究结果为华北大黑鳃金龟的预测预报以及针对性防治提供了基础。     

铜绿丽金龟对寄主植物挥发物的触角电生理及行为反应

为深入了解铜绿丽金龟的取食行为,探索开发安全高效的植物源引诱剂,应用昆虫触角电位反应仪和Y型嗅觉仪测试其对不同寄主植物挥发物的趋向行为差异,并根据室内行为结果配制诱剂进行大田试验。结果表明:铜绿丽金龟雄虫对水杨酸甲酯和(1,1’-联环戊基)-2-酮的触角电位反应(electroantennography,EAG)值显著高于其它试剂;石竹烯和水杨酸甲酯能引起雌虫触角较强的电位反应;乙酸顺式-3-己烯酯和石竹烯分别对雄虫和雌虫有较高的嗅觉选择反应率,分别达0.95和0.94。综合EAG和嗅觉试验结果,选择对雌、雄虫均有较好引诱效果的反式-2-己烯醛、乙酸顺式-3-己烯酯、石竹烯、(1,1’-联环戊基)-2-酮和水杨酸甲酯进行田间试验,最终筛选到铜绿丽金龟雄虫的最适引诱剂为每诱芯360 mg乙酸顺式-3-己烯酯,雌虫的最适引诱剂为每诱芯360 mg石竹烯,日诱虫量分别可达33.00±1.53头和29.33±1.45头。     

(Z)-3-hexenyl acetate and 1-undecanol increase male attraction to sex pheromone trap in Grapholita molesta (Busck) (Lepidoptera: Tortricidae)

The effects of host-plant volatiles (HPVs) on male oriental fruit moth, Grapholita molesta (Busck) (Lepidoptera: Tortricidae), and response to sex pheromone trap were studied in a pear orchard. Two HPVs compounds, (Z)-3-hexenyl acetate and 1-undecanol, combined with sex pheromone of G. molesta in traps were tested. The results showed that most of the male moths were captured in the traps baited with the sex pheromone combined with these two HPVs compounds than by the pheromone alone. Also, more males were captured by the trap containing pheromone plus (Z)-3-hexenyl acetate than by the one containing 1-undecanol. It appeared that these HPVs act as sex pheromone synergists to enhance the attraction of male G. molestato pheromone traps, since males were not captured in the traps baited only with (Z)-3-hexenyl acetate and/or 1-undecanol.     

Contact and fumigant toxicity of Armoracia rusticana essential oil, allyl isothiocyanate and related compounds to Dermatophagoides farinae

BACKGROUND: The toxicity to adult Dermatophagoides farinae of allyl isothiocyanate identified in horseradish, Armoracia rusticana, oil and another 27 organic isothiocyanates was evaluated using contact + fumigant and vapour‐phase mortality bioassays. Results were compared with those of two conventional acaricides, benzyl benzoate and dibutyl phthalate. RESULTS: Horseradish oil (24 h LC₅₀, 1.54 µg cm^?2) and allyl isothiocyanate (2.52 µg cm^?2) were highly toxic. Benzyl isothiocyanate (LC₅₀, 0.62 µg cm^?2) was the most toxic compound, followed by 4‐chlorophenyl, 3‐bromophenyl, 3,5‐bis(trifluoromethyl)phenyl, cyclohexyl, 2‐chlorophenyl, 4‐bromophenyl and 2‐bromophenyl isothiocyanates (0.93–1.41 µg cm^?2). All were more effective than either benzyl benzoate (LC₅₀, 4.58 µg cm^?2) or dibutyl phthalate (24.49 µg cm^?2). The structure‐activity relationship indicates that types of functional group and chemical structure appear to play a role in determining the isothiocyanate toxicities to adult D. farinae. In the vapour‐phase mortality bioassay, these isothiocyanates were consistently more toxic in closed versus open containers, indicating that their mode of delivery was, in part, a result of vapour action. CONCLUSION: In the light of global efforts to reduce the level of highly toxic synthetic acaricides in indoor environments, the horseradish oil‐derived compounds and the isothiocyanates described herein merit further study as potential acaricides for the control of house dust mite populations as fumigants with contact action.

对大黑鳃金龟甲幼虫高效的苏云金芽胞杆菌筛选及cry基因鉴定

为获得对大黑鳃金龟甲幼虫具有较高杀虫活性的菌株,利用拌土法测定了本实验室分离的500株苏云金芽胞杆菌(Bacillus thuringiensis,Bt)对大黑鳃金龟甲的杀虫活性,建立Bt菌株比较鉴别技术来进行多样性分析,并对菌株的晶体形态及幼虫感染Bt后的中肠组织切片进行观察。结果显示,从500株Bt菌株中筛选到42株对大黑鳃金龟甲幼虫具有不同程度活性的菌株,分属于14个菌株类型;其中有10株校正死亡率大于60%,261-1菌株杀虫活性最高,7 d校正死亡率达100%。从14个菌株类型中各选取1个代表菌株进行基因鉴定,仅P65-1、1126-1、FCD114和78-2菌株分别含有cry8Ma、cry8Ca、cry8Ab、cry8Ga、cry8Ea共5个cry8类新基因,其它10个菌株均不含cry3、cry8、cry18、cry23、cry37、cry43等对鞘翅目害虫有效的杀虫基因。14个菌株中,78-3、127-2和1198-1菌株能产生双锥体型晶体,261-1、FCD114、P65-1、FTL84、78-2和1126-1菌株能产生球形晶体。幼虫感染261-1、1198-1、FCD114、1126-1、QDL40-2菌株后,中肠组织发生明显的病理变化:2 d时肠壁细胞明显出现空洞化,排列疏松,4 d时受到严重破坏并脱离底膜。表明筛选到的Bt菌株具有防治大黑鳃金龟甲幼虫的潜力。     

淮北地区农田金龟子三种优势种在土壤中垂直活动规律观察

在安徽省淮北地区,暗黑金龟子Holotrichia parallela Motsehulsky和铜绿金龟子Anomala corpulenta MotschuIsky 1年发生1代,一般以三龄幼虫越冬;大黑金龟子Holotrichia oblita Faldermann两年发生1代,以成虫和三龄幼虫交替越冬。三种金龟子相同虫态(龄、期)在地下的垂直分布基本一致。3月下旬至4月上旬,铜绿、大黑金龟子越冬幼虫上升为害,而暗黑金龟子越冬幼虫则停留在越冬土室内直至化蛹。大黑金龟子成虫羽化后蛰伏至翌年4月,然后出土;另两种成虫羽化后于当年5月下旬开始出土。从成虫出土后至三龄幼虫下蛰前,群体分布在浅土层。幼虫为害夏季作物,并在下蛰前为害秋播小麦。土温决定了幼、成虫春季的上升和秋季的下蛰。群体在浅土层活动期,土壤湿度是群体升降的主要因素。土壤结构、寄主植物成熟期和幼虫龄期均能影响群体的垂直分布。暗黑金龟子从三龄幼虫下蛰至羽化成虫上升,这期间群体垂直分布不变,呈正态分布。     

7种林木植物对华北大黑鳃金龟取食和繁殖的影响

为明确华北大黑鳃金龟Holotrichia oblita(Faldermann)的嗜食植物,优化其室内人工饲养技术及为诱虫植物提供候选材料,以花生叶片为对照,研究了7种林木植物叶片对华北大黑鳃金龟取食和繁殖的影响。结果表明,华北大黑鳃金龟对8种植物日均取食量由高到低依次为金叶女贞、刺槐、核桃、榆树、花生、柳树、香椿、毛白杨,其中金叶女贞、香椿和毛白杨与花生间有极显著差异,金叶女贞与刺槐、核桃、榆树间无显著差异;单雌产卵量由高到低依次为金叶女贞、柳树、核桃、香椿、花生、榆树、毛白杨、刺槐,其中金叶女贞、柳树、核桃、刺槐与花生间有极显著差异,而金叶女贞与柳树间无显著差异。研究表明,饲养华北大黑鳃金龟成虫适宜饲料植物为金叶女贞,日均取食量最高为4.70 g,产卵期最长为56.00 d,单雌产卵量最多为58.88个,其次为核桃和柳树。     

Acaricidal activities of paeonol and benzoic acid from Paeonia suffruticosa root bark and monoterpenoids against Tyrophagus putrescentiae (Acari: Acaridae)

The acaricidal activities of paeonol (2'-hydroxy-4'-methoxyacetophenone) and benzoic acid identified in the root bark of tree peony, Paeonia suffruticosa Andrews, against copra mite, Tyrophagus putrescentiae (Schrank), adults were examined using direct contact and vapour phase toxicity bioassays and compared with those of cinnamyl acetate, cinnamyl alcohol and 37 monoterpenoids as well as the acaricides benzyl benzoate, dibutyl phthalate and N,N-diethyl-m-toluamide (DEET). Based on LD(50) values in fabric piece contact toxicity bioassays, the acaricidal activities of benzoic acid (4.80 microg cm(-2)) and paeonol (5.29 microg cm(-2)) were comparable to that of benzyl benzoate (4.46 microg cm(-2)) but more pronounced than those of DEET (30.03 microg cm(-2)) and dibutyl phthalate (25.23 microg cm(-2)). In vapour phase toxicity bioassays, paeonol and benzoic acid were much more effective in closed containers than in open ones, indicating that the effects of these compounds were largely due to action in the vapour phase. As judged by 24 h LD(50) values, (1S)-(-)-verbenone (7.42 mg per disc) was the most toxic fumigant, followed by (1S)-(-)-camphor, (S)-(+)-carvone, (R)-(-)-linalool and (+/-)-camphor (10.45-18.18 mg). Potent fumigant toxicity was also observed with paeonol, (2S,5R)-(-)-menthone, (+/-)-citronellal, benzoic acid, (1S,4R)-(-)-alpha-thujone and (R)-(+)-pulegone (25.10-34.63 mg). Neither benzyl benzoate, DEET nor dibutyl phthalate caused fumigant toxicity. Paeonia root bark-derived materials, particularly paeonol and benzoic acid, as well as the monoterpenoids described, merit further study as potential acaricides or as leads for the control of T. putrescentiae.

Attraction of <Emphasis Type="Italic">Parastethorus nigripes</Emphasis> and other insect species to methyl salicylate and (<Emphasis Type="Italic">Z</Emphasis>)-3-hexenyl acetate dispensers in a citrus grove and vineyard in south-eastern Australia

Herbivore-induced plant volatiles (HIPVs) play an important role in tritrophic interactions, and have the potential to attract beneficial arthropods into crops to enhance biological control of target pests. We conducted field trials in citrus and grapes to evaluate the response of abundant insect species to two HIPVs, methyl salicylate (MeSa) and (Z)-3-hexenyl acetate. Micromus tasmaniae (Hemerobiidae) showed significant attraction to MeSa, but only in the vineyard trial. Parastethorus nigripes (Coccinellidae) was also attracted to MeSa in the vineyard, but in the second citrus trial the treatment response was just outside the nominal 5% significance level. In the first citrus trial where P. nigripes was not separated taxonomically from the closely related coccinellid Stethorus vagans, a combined analysis was undertaken and significant attraction of both coccinellid species to MeSa was also observed. There was also a significant positive combined response of P. nigripes and S. vagans to (Z)-3-hexenyl acetate in the first citrus trial. Other predatory insect species did not respond to MeSa or (Z)-3-hexenyl acetate. As compared with the vineyard trial, weaker attraction of some insect species in the citrus trials may reflect high levels of background odour in the citrus orchard that could have interfered with normal insect olfactory responses. Our results support previous studies demonstrating coccinellids in the tribe Stethorini are often strongly attracted to MeSa. Deploying MeSa dispensers in vulnerable crops could attract increased numbers of P. nigripes, enhancing the biological control of pest tetranychid mites in Australian horticultural systems and reducing or eliminating the need for miticide applications.     

Volatile organic compounds (VOCs) from cereal plants infested with crown rot: their identity and their capacity for inducing production of VOCs in uninfested plants

When infested with Fusarium sp., the cereals Triticum aestivum L. emend. Fiori et Paol. cv. ‘Bombona’, Avena sativa L. cv. ‘Deresz’, and Hordeum vulgare L. cv. ‘Rastik’ can emit volatile organic compounds (VOCs). The VOCs differ both qualitatively and quantitatively from those emitted by non-infested wheat, oat, and barley plants. We detected increased amounts of VOCs released by green leaves (green leaf volatiles – GLVs): (Z)-3-hexenal, (E)-2-hexenal, (Z)-3-hexen-1-ol, (E)-2-hexen-1-ol, (Z)-3-hexen-1-yl acetate, 1-hexyl acetate as well as the other VOCs like (Z)-ocimen, linalol, linaloloxide, benzyl acetate, indole, and β-caryophyllene. The lipoxygenase pathway resulted in the highest release of GLVs in comparison to the other biochemical pathways of volatile production. As a result of Fusarium infestation, the amounts of VOCs varied between tested cereals. We also subjected uninfested wheat, barley, and oat plants to infested wheat plants, and found that these cereals released larger amounts of VOCs compared to control plants. Emitted amounts of VOCs were significantly higher the shorter the distance between uninfested and infested plants.
