The ability of these isolates to kill D. citri , two Cacopsylla species ( Hemiptera: Psyllidae ) , and the brown citrus aphid, Toxoptera citricida ( Kirkaldy ) and the effect of temperature in vitro on their growth were investigated. Infection with all three isolates resulted in high mortality for D. citri . In the Cacopsylla spp. and T. citricida , some isolates caused consistent mortality, but this varied among isolates. Mycelial growth of the three isolates was vigor- ous at 20–30 (cid:155) C. The two isolates of B. bassiana grew well at 25 (cid:155) C, while the I. fumosorosea isolate grew well at 25–30 (cid:155) C, indicating that the optimal growth temperature varied among the isolates.","PeriodicalId":14568,"journal":{"name":"Japanese Journal of Applied Entomology and Zoology","volume":null,"pages":null},"PeriodicalIF":0.5,"publicationDate":"2020-08-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85212714","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A decision tree analysis was performed on the non-treated data. The tree-model had four terminal nodes and was split by three factors: soybean continuous cropping year, damage rate in the previous year, and distance to the nearest field where soybeans were cropped in the previous year. The four terminal nodes were ordered from low to high according to the damage level of the fields classified to each node. The order of nodes did not differ between the modeling data and test data, which were data from other uncontrolled fields. As the number of insecticide treatments increased, the ratio of low-damage-level fields increased to > 90% in all terminal nodes except the highest-damage-level node. These results indicate that the order of the four terminal nodes may represent the order of damage risk. The tree-model may enable rational selection of the number of insecticide treatments or rotation of soybean to rice before planting.","PeriodicalId":14568,"journal":{"name":"Japanese Journal of Applied Entomology and Zoology","volume":null,"pages":null},"PeriodicalIF":0.5,"publicationDate":"2020-08-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87567052","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Today, 12 years have passed, and the use of IPM with biological control agents(BCA)has spread to many agricultural production sites. Dissemination and extension activities of IPM were promoted not only in the greenhouse cultivation of tomatoes, strawberries, sweet peppers, cucumbers, eggplants, melons, watermelons, ornamentals, and citruses, but also spreading to eggplants in the open field from 2015. As a result, in strawberries, sweet peppers, eggplants, cucumbers, and citruses grown in greenhouse, IPMs, which are mainly used by natural enemies as the main BCA, are considered to have increased dramatically due to the following three major contributions. 1)For a stable and successful IPM program, it was important to let the natural enemy density grow before increasing pest insects by using generalist predatory mites, such as Neoseiulus californicus and Amblyseius swirskii. 2)Demonstration tests were conducted in which extension officers planned, verified, and evaluated with the growers, which led to an improvement in their knowledge and skills. 3)As we conducted multifaceted demonstration tests in Japan, the sharing of information on the techniques of using IPM programs has progressed in a short period of time. However, for tomatoes, ornamentals, melons, and watermelons, a lack of solution tools against disease control and the cost performance of control programs have been issues, and the use of IPM programs is becoming less popular. In order to establish IPM techniques, we think it is important to conduct dissemination activities for showing the benefits of IPM leading to problem-solving for each region and grower, and for growers to recognize the merit of selecting IPM.","PeriodicalId":14568,"journal":{"name":"Japanese Journal of Applied Entomology and Zoology","volume":null,"pages":null},"PeriodicalIF":0.5,"publicationDate":"2020-08-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79190114","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
