Bactrocera zonata originates in South and South-East Asia. It attacks more than 50 host plants, several of which are commercial species-guava, mango, peach, apricot, fig and citrus. The probable risk of its introduction to a new country is aided by travel and trade, and is influenced by changes in climate and land use. The EPPO classified it as A1 Pests, suggesting for regulation as a quarantine pest. Zeugodacus tau is widespread in Asia and Australia. It attacks 34 hosts from 9 families, major commercial hosts-melon, cucumber, pumpkin, luffa, sapodilla, bitter gourd and guava. The aim of the study was to identify polytene chromosomes from the 3 rd instar larval salivary glands and to construct structural polytene maps based on the banding patterns of the polytene arms. In both species, five polytene chromosomes (10 polytene arms) corresponding to the five autosomes of the mitotic chromosomes and a heterochromatic mass were observed in polytene nuclei. Hetero-chromatic mass is a granular network and supposed that it corresponds to sex chromosomes. Poly-tene maps were constructed by dividing each of chromosome arms into twenty sections. The tips of each chromosome arm, prominent landmarks, characteristic banding patterns and puffs were recognized that reflected the fundamental differences in the chromosomes. The structural maps presented here allow future identification and location of chromosomal rearrangements or structural differences within other tephritid species.","PeriodicalId":109312,"journal":{"name":"Proceedings of The 1st International Electronic Conference on Entomology","volume":"72 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133864396","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}

Kiss","doi":"10.3390/iece-10488","DOIUrl":"https://doi.org/10.3390/iece-10488","url":null,"abstract":": The invasive spotted wing drosophila (SWD - Drosophila suzukii (Matsumura, 1931)) became an important pest in several parts of Europe in less than one decade. High variations are re-ported by geographical regions in the phenology of the species and thus in the damages in different soft-skinned fruits. Our study aimed to compare phenological patterns of SWD in various neighbouring habitats (cherry/sour cherry and blackberry plantations, forested and built-up areas) in a hilly berry production region of Hungary (Nógrád county). The investigation consisted of operating 16 bottle traps (with vinegar and red wine) on eight spots during four years (2017-2020). The traps in cherry/sour cherry plantations caught the highest number of SWD (n=21997), which was followed by forests (n=20616), built-up areas (n=10567) and blackberry plantations (n=5035). No substantial differences were found in phenological patterns between the habitat types in any year; the catches did not reflect the lack of ripening fruits. The highest numbers of SWD imagoes were caught in September and October, while virtually no SWD individuals were caught before July. The lack of SWD catches in the first half of the year suggests that long-distance migration may play an essential role in the population dynamic of SWD by re-establishing pest populations regularly in mid-sum-mer in Hungary.","PeriodicalId":109312,"journal":{"name":"Proceedings of The 1st International Electronic Conference on Entomology","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132637042","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}

Ahmed, Xutong Wei","doi":"10.3390/iece-10504","DOIUrl":"https://doi.org/10.3390/iece-10504","url":null,"abstract":": Mosquitoes are the vectors of numerous deadly diseases including Yellow Fever, Malaria, Dengue fever, Zika and Chikungunya. Numerous control measures are being implemented around the world to suppress this notorious insect. Mosquito systematics is essential to study the mosquito prevalence in a definite area, which helps entomologists to design and implement specific control measures for prevalent species. Traditional systematics methods are laborious and time-consuming, which can be overcome by different image-processing based machine-learning (ML) approaches. But due to small size and poor-quality images, ML approaches often fail to identify mosquitoes from images. Recently, wing beating sounds showed potential to be used as a classifier in mosquito systematics. The current study aims to develop an ML model to identify different genera and species of mosquitoes, based on wing-beating sounds and propose a computationally inexpensive and fast tool to be used in mosquito control programmes. Wing beating sounds of six mosquito species of three different genera were collected from publicly available sources, and several state-of-art ML models were implemented on raw sounds as well as in processed spectrograms. On raw sounds, the general neural network model with 3 dense layers perceptrons reached at 59% accuracy, whereas for processed spectrograms, Resnet-18 enhance the accuracy to 86.1%. The model also showed potential to enhance the accuracy for the identification of different mosquitoes' sexes. Our model has implications to be served as a mosquito prevalence monitoring tool and assist mosquito eradication program for specific mosquito genera, and finally will help medical practitioners to work on related pathogens.","PeriodicalId":109312,"journal":{"name":"Proceedings of The 1st International Electronic Conference on Entomology","volume":"301 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133532116","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}

As one of the main methods for controlling this pest, the overuse of broad-spectrum insecticides is applied. Population sampling methods are fundamental in the chemical control-based IPM system, minimizing the negative effects of insecticides on the environment. A tentative sampling method for LDM is recommended; however, conventional sampling schemes are complained due to the time-consuming. Alternatively, binomial sequential sampling plans are often more efficient and may allow samplers to fast classify pest infestations and make a control decision. The objectives of this study were to determine the spatial distribution and develop binomial sequential sampling for fast reliable estimation of LDM infestation on date palms. Throughout the province of Basra, Iraq, eighty-four 1 ha date palm orchards were sampled from 2017 to 2019. The results of spatial distribution pattern analyses by using TPL (a = 0.0695 and b = 1.4041) indicated that LDM on sampling units (date palm spikelets) were highly aggregated in date palm orchards. The mean vs. proportion infested (PT-m) (T= 0 to 5) models for LDM infesting sampling units (spikelets) revealed relatively strong fits for LDM. Binomial sequential sampling models for LDM infesting date palms were developed for action thresholds of 0.15, 0.25, and 0.35 proportions of spikelets with at least three infested fruit (T=3). Binomial sequential sampling plans were validated using RVSP software by the evaluation of operating characteristic functions and average sample number. We recommend a minimum sample size of 28 and sampling efforts should be terminated at 90 samples for these sampling plans.","PeriodicalId":109312,"journal":{"name":"Proceedings of The 1st International Electronic Conference on Entomology","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121203731","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}
