Arthropod fauna and main insect pests of plane trees in Israel

Fifty-four insect and four mite species are included in a list of the entomofauna of plane trees in Israel. Only two species are monophagous:Phyllonorycter platani (Stgr.) (Lepidoptera: Gracillariidae) andEdwardsiana iranicola Zachv. (Heteroptera: Cicadellidae). Four species are noxious:P. platani, the main insect pest of the plane trees in Israel;Zeuzera pyrina L. (Lepidoptera: Cossidae);Kalotermes flavicollis F. (Isoptera: Kalotermitidae); andE. iranicola. Of much lesser importance areTargionia vitis Sign. (Homoptera: Diaspididae),Heliothrips haemorrhoidalis Bché. andRetithrips syriacus May. (Thysanoptera: Thripidae). About half of the listed species are natural enemies and many are parasites ofP. platani. Details are given on the noxious species, together with recommendations for prevention and control.

野生苎麻主要病虫害发生与防治技术

苎麻在我国长江以南地区广为栽培，其韧皮纤维为纺织原料中的天然纤维之上品，国际上称为“中国草（China Grass）”，而荨麻科苎麻属野生苎麻种是未被利用的种质资源，是苎麻遗传育种及相关基础研究的珍贵材料。在野生苎麻种质资源中蕴藏着很多栽培种所没有的优异基因，如抗寒、抗旱、抗虫、抗病、抗倒伏、无融合生殖等优异基因。这些优异基因，丰富了作物基因供体，对加速新品种选育，促进国民经济发展具有重大的战略意义。

泰安市核桃园主要病虫害发生情况及其化学防治用药流程

为明确山东省泰安市核桃园主要病虫害的发生情况及其化学防治的用药流程,于2017—2018年采用田间调查法进行主要病虫害的调查,于2019年采用常规喷雾法对不同防治对象进行化学防治,研究不同用药时间及用药次数下3种农药对核桃的保果效果及对主要病虫害的防治效果,确定用药流程。结果表明,2017年泰安市核桃园主要病虫害以核桃细菌性黑斑病、核桃炭疽病和核桃举肢蛾Atrijuglans aristata为主,造成的病虫果率达83.25%。5月中旬至6月下旬,以核桃细菌性黑斑病和核桃举肢蛾单独发生为主;7月上旬至8月上旬,以核桃细菌性黑斑病和核桃炭疽病单独发生为主;8月中旬至下旬,以核桃炭疽病单独发生和核桃炭疽病+核桃细菌性黑斑病共同发生为主。2018年3种病虫害造成核桃的总体落果率为79.84%,共出现2次落果高峰,即在6月下旬以核桃举肢蛾造成的落果和在8月下旬以核桃炭疽病单独发生和核桃炭疽病+核桃细菌性黑斑病共同发生造成的落果。针对以上3种主要病虫害,在核桃生长期应至少喷药6次,其总体的保果效果和防治效果分别达到96.58%和93.70%,分别显著高于喷药4次的83.72%和70.56%,与喷药8次处理差异不显著。在实际生产中,建议对核桃细菌性黑斑病自5月上旬至8月上旬,每15~20 d用药1次,至少用药6次;对核桃炭疽病自6月下旬至8月上旬,每15~20 d用药1次,至少用药4次;对核桃举肢蛾在5月下旬和7月下旬各用药1次。

Resistance of tomato accessions from the horticulture germplasm bank to red spider mites: exploring mite preference patterns and antixenosis mechanism

The red spider mite Tetranychus evansi can cause up to 90% yield losses to tomato crops. Mechanisms and causes of plant resistance to this pest could contribute to improved planning of plant breeding programs that prevent damage by this pest. It is known that the morphology and chemical compounds present in tomato plants are important to Tetranychus spp. success. This study aims at evaluating the resistance of 84 arbitrarily chosen tomato accessions – obtained from the Horticulture Germplasm of the Universidade Federal de Viçosa (HGB-UFV), Minas Gerais State, Brazil – to T. evansi. We evaluated the number of spider mites per leaf disk, number of trichomes/mm2, and the concentration of hydrocarbons of leaf disk. A significant difference in the number of T. evansi adults/leaf disk was found among accessions. The resistance mechanism of the HGB-UFV accessions was determined to be antixenosis. Accessions 2004, 2098, 2121, and 2100 had higher trichome density and the lowest adult T. evansi per tomato leaf disk. For this reason, these accessions should be chosen as sources of resistance in plant breeding programs. The hydrocarbons C₁₁, C₁₃, and C₂₂ had a negative correlation with T. evansi adults per leaf disk.

Status of pesticide resistance in arthropod pests in Israel

A complex of events and factors, pertinent to a specific insect and insecticide, governs the development of resistance to insecticides. In Israel, resistance to conventional and novel insecticides occurred in insect pests such asBemisia tabaci andSpodoptera littoralis (that damage agricultural crops),Tribolium castaneum and other flour beetles (that contaminate stored products), andPediculus humanus spp., house flies and mosquitoes (that threaten public health). In the mid-1980s an insecticide resistance management (IRM) strategy was established for all cotton grown in Israel and is being adjusted on a yearly basis as needed. At present, insect pest management and IRM strategies are being developed and implemented area-wide for three regions in Israel: Bet She’an Valley, western Galilee, and western Negev. There are several research groups now working in Israel on various aspects of resistance including occurrence, mechanisms, and management practices. This paper offers a tentative review of the status of insecticide and acaricide resistance in pests in Israel.
