Smith) (Lepidoptera: Noctuidae) is a highly destructive polyphagous pest that primarily damages maize. Maize is considered a most versatile crop for growing intercrops due to the wide row it needs. Maize-pea intercropping is preferred by small and marginal farmers worldwide due to various advantages including higher yield and improved economic benefits. However, the success of this intercropping system may be hampered if pea could sustain the FAW population. Thus, to clarify the fitness and potential effect of <i>S. frugiperda</i> on pea, we analysed the survival and development of <i>S. frugiperda</i> fed on pea leaves in the laboratory and constructed age-stage and two-sex life tables. Results showed that FAW successfully completed its life cycle when fed on pea and produced fertile offspring. The pre-adult duration was significantly higher on pea than maize. The net reproductive rate, intrinsic and finite rate of population increase on pea (135.06 offspring per individual, 0.12 offspring per individual per day and 1.13 times per day) were all significantly different from those on maize (417.64 offspring per individual, 0.19 offspring per individual per day and 1.21 times per day). The probability of survival of <i>S. frugiperda</i> at each stage was lower when fed on pea leaves than that of maize-fed larvae. Due to the overlapping growth periods of the maize and pea, <i>S. frugiperda</i> can easily proliferate throughout the year by shifting between adjacent crops.

{"title":"Predicting the current and future suitable distribution range of Trilocha varians (Walker, 1855) (Lepidoptera: Bombycidae) in China","authors":"Qianqian Qian, Danping Xu, Wenkai Liao, Zhihang Zhuo","doi":"10.1017/s0007485324000117","DOIUrl":"https://doi.org/10.1017/s0007485324000117","url":null,"abstract":"<jats:italic>Trilocha varians</jats:italic> is one of the major pests of <jats:italic>Ficus</jats:italic> spp. Based on 19 bioclimatic variables provided by the Worldclim, our study analysed the suitable distribution areas of <jats:italic>T. varians</jats:italic> under current and future climate changes (SSP1-2.6, SSP2-4.5, SSP5-8.5) for two periods (the 2050s and 2090s) using the maximum entropy algorithm (MaxEnt) model. Key environmental variables affecting the geographic distribution of <jats:italic>T. varians</jats:italic> were also identified, and the changes in the area of suitable range under current and future climate changes were compared. The results showed that the key environmental variables affecting the distribution of <jats:italic>T. varians</jats:italic> were temperature and precipitation, comprising annual mean temperature (bio1), temperature seasonality (standard deviation × 100) (bio4), precipitation of driest month (bio14), and precipitation of driest quarter (bio17). Under the current climatic conditions, the suitable distribution area of <jats:italic>T. varians</jats:italic> is within the range of 92°13′E–122°08′E, 18°17′N–31°55′N. The current high, medium, and low suitable areas for <jats:italic>T. varians</jats:italic> predicted by the MaxEnt model are 14.00 × 10<jats:sup>4</jats:sup>, 21.50 × 10<jats:sup>4</jats:sup>, and 71.95 × 10<jats:sup>4</jats:sup> km<jats:sup>2</jats:sup>, of which the high suitable areas are mainly distributed in southern Guangdong, southwestern Guangxi, western Taiwan, Hong Kong, and Hainan. Under different future climatic conditions, some of the high, medium, and low suitability zones for <jats:italic>T. varians</jats:italic> increased and some decreased, but the mass centre did not migrate significantly. The Pearl River Basin is predicted to remain the main distribution area of <jats:italic>T. varians</jats:italic>.","PeriodicalId":9370,"journal":{"name":"Bulletin of Entomological Research","volume":"22 1","pages":""},"PeriodicalIF":1.9,"publicationDate":"2024-05-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140831396","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
