The longest development durations were recorded when larvae reared on corn flour without bran followed by bran only (31.1±0.28 and 31.5±0.34 days, respectively). The highest larval survival rate was 95% when larvae reared on whole wheat flour, whereas the lowest one was 94% when larval reared on both of flour without bran and bran only. Meanwhile the lowest survival rates were 84% and 83% when larvae reared on corn flour without bran and bran only, respectively. The longest oviposition period was recorded on wheat flour without bran (280.5±5.70 days). The adult longevity was the longest on wheat flour without bran. The number of progeny produced by the first generation was higher on whole flour than flour without bran. The large differences between the various flour types suggest varying levels of risk by insect infestation.

Grey mould disease, which caused mainly by Botrytis cinerea , is a serious disease significantly reduces strawberry production globally. Protective fungicides considered essential tool in management strategies. Recently, fungicides ineffectiveness observed widely in many countries. Therefore, this investigation carried out to test the sensitivity of 311 isolates of Botrytis cinerea collected between 2019 and 2021 from strawberry open fields in Egypt's major strawberry-producing governorates (Beheira, Ismailia, Qalyubie, and Dakahlia) to diethofencarb, iprodione and carbendazim. The isolates were tested to distinguish resistant isolates and determine the EC 50 values for sensitive and resistant isolates. The results showed that 7.4, 37.94 and 93.77% of the isolates found to be resistant to diethofencarb, iprodione and carbendazim, respectively. During the 2019 and 2021, resistance frequencies among B. cinerea isolates significantly increased, rising from 91.91% to 96% for carbendazim, from 10.29% to 16% for diethofencarb, and from 22.79% to 59% for iprodione. The mean EC 50 values for the sensitive isolates were 0.021, 0.027 and 0.0548µg/ml, while the mean EC 50 values for the resistant isolates were 141.06, 24.94 and 0.7161 µg/ml for carbendazim, diethofencarb and iprodione, respectively. There were little variations in osmotic sensitivity to NaCl between iprodione sensitive and resistant isolates. All carbendazim resistant isolates detected were sensitive to diethofencarb except three isolates showed dual resistance to diethofencarb and carbendazim.","PeriodicalId":16820,"journal":{"name":"Journal of Plant Protection and Pathology","volume":"22 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-08-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77273145","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

More than five thousand hectares of land in Egypt are used to grow strawberries. Fusarium wilt in strawberries caused by Fusarium oxysporum can severely decrease production. The essential strategy to control the disease is the application of protective fungicides. Recently, the fungicides commonly used to control the disease lost their efficiency due to the emergency of resistant populations. The current study aims to detect resistance frequency to QoI fungicides azoxystrobin and trifloxystrobin in addition to finding an appropriate control strategy. 113 F. oxysporum isolates were collected from four main strawberry-producing governorates (Beheira, Ismailia, Dakahlia and Qalyubia) and subjected to bioassay assessment. The results showed that among 113 isolates collected, only 42 (37.2%) isolates were resistant to azoxystrobin while 36 (31.9%) isolates were resistant to trifloxystrobin. EC 50 of azoxystrobin and trifloxystrobin were determined for a set of sensitive and resistant isolates using the mycelial growth inhibition technique. The EC 50 mean value for azoxystrobin-sensitive isolates was 0.0209 µg/ml while, the EC 50 mean value for azoxystrobin-resistant isolates was 0.4544 µg/ml. For trifloxystrobin, the EC 50 mean value for sensitive isolates was 0.0174 µg/ml, while the EC 50 mean value for resistant isolates was 0.2232 µg/ml. The combination of tebuconazole 50% and trifloxystrobin 25% tested with two concentrations 10 and 100 µg/ml showed high ability in the management of azoxystrobin and trifloxystrobin-resistant isolates and exhibited 100% mycelial growth inhibition.","PeriodicalId":16820,"journal":{"name":"Journal of Plant Protection and Pathology","volume":"39 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85678770","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is the largest viroid of citrus with 371 nucleotides. The disease causes distinguished symptoms of bark scaling on rootstocks of citrus trees grafted onto trifoliate rootstocks causing severe stunting of trees grafted on these rootstocks. The use of indicator host plants for CEVd detection had been successful using clean matured fresh cuttings of specific indicators (Etrog lemon, Volkameriana lemon), which were grafted with the infected plants and cultured in plastic bags after a short dipping in IBA solution for 10 sec. Ideal clear symptoms were observed 18 days after grafted inoculation on new growing leaves of unique indicators. The obtained results of the biological indexing trail were confirmed using RT-PCR and transmission assays using some hosts such as Solanum melongena, Piper nigrum , Gynura auranisa and Solanum esculentum (Castel rock) with infectious sap. Results showed that cold treatment at 4 °C for 6 months companies with chemotherapy with 10, 20 and 30 mg/L Virazol and thiouracil gave plants free-viroid. viroid infection was reduced by using the highest concentrations of Virazol and thiouracil at 30 mg/L reaching 80 and 55%, respectively. The recovered plants were examined by RT-PCR. Cold therapy treatment and chemotherapy are effective and attractive techniques for eradicating CEVd from citrus trees in Egypt. Virazol has the greatest effect on the elimination of viroid because the viroid-free percentages by Virazol were higher than those obtained using thiouracil.","PeriodicalId":16820,"journal":{"name":"Journal of Plant Protection and Pathology","volume":"78 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-06-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77426286","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Obtained results showed that mean incubation period of egg were 2.75 and 3.06 days, while larval durations were 16.26 and 22.03 days and pupal duration lasted 9.93 and 10.40 days, respectively, after rearing on maize and castor bean leaves, respectively. Means of total egg production were 1836.67 and 1562.33 eggs/female by rearing on these two hosts, respectively. Pre-oviposition; oviposition and post-oviposition periods were 3.36, 6.77 and 2.20 days, for females fed during larval stage on maize leaves, opposed to 4.97, 5.80 and 2.50 days when reared on castor bean leaves. Adult longevities were longer by feeding larvae on castor bean leaves than on maize leaves. Also, results indicated that FAW growth indices were higher by feeding on maize leaves than on castor bean leaves. So for rearing S. frugiperda , maize leaves may be used as preferred, but castor bean leaves can be also, successfully used in case of the absence of the former host plant.","PeriodicalId":16820,"journal":{"name":"Journal of Plant Protection and Pathology","volume":"10 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-06-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84219445","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
