PREFACE: Proceedings of the XIV International Symposium of Neuropterology

ABSTRACT The XIV International Symposium of Neuropterology (ISN) was held online, between May 23rd and 27th of 2022, with the Universidade Federal de Lavras, Minas Gerais, Brazil as responsible for the event. This event was carried out for and by researchers with interest in any aspects of biology, systematics, taxonomy, natural history, evolution, and applied studies on the insects of the superorder Neuropterida (Neuroptera, Megaloptera and Raphidioptera). This was the first meeting organized by a South American country, and the first one held online. A total of 141 participants from 24 countries attended the meeting, which was considered the largest number of registered participants among all the versions of the ISN and resulted in 10 keynote lectures (including the Opening Lecture), 21 oral presentations, and 17 poster presentations. The papers in this volume are representative of the lectures, oral presentations, and posters presented at the meeting. We dedicate these proceedings to the memory of the Professor and entomologist Dr. César Carvalho, who was directly responsible for bringing this meeting to Brazil, but unfortunately passed away in September 2018.

First record of the genus Lainius Navás, 1913 (Neuroptera: Chrysopidae) in Mexico, with notes on the distribution of Apochrysinae

ABSTRACT The species Lainius constellatus Navás is recorded for the first time from Mexico; thus this report represents the northernmost record of the genus and species for the Americas. In addition, it provides data on the variation in color marks and a description of the hypandrium internum. A brief summary of the distribution of the species belonging to the subfamily Apochrysinae is provided, with emphasis on the three American genera, which share distribution mostly in the Pacific domain of the Brazilian subregion, ranging from the Mexican transition zone to possibly the Chacoan subregion.

Influência de diferentes cultivos e fatores climáticos na ocorrência de crisopídeos em sistema agroecológico / Influence of different crops and climate factors on the occurrence of green lacewings in agroecological system

Os insetos predadores da família Chrysopidae têm sido relatados tanto em ecossistemas naturais como nos agroecossistemas, sejam eles cultivos consorciados ou monocultivos. Porém, são escassas as informações sobre o comportamento das populações desses insetos nos agroecossistemas diversificados, como aqueles de base agroecológica. O presente trabalho teve o objetivo de determinar a riqueza de espécies de crisopídeos e avaliar a influência de diferentes cultivos agrícolas, assim como de fatores climáticos na abundância desses insetos em sistema de produção orgânica diversificada. O estudo foi conduzido de setembro de 2008 a agosto de 2009, por meio de amostragens semanais de adultos de Chrysopidae em áreas do Sistema Integrado de Produção Agroecológica, em Seropédica (RJ), cada qual com um tipo de sistema de cultivo (rotação milho-mucuna/olerícolas, cafeeiros sombreados e rotação cana-de-açúcar/pastagem de braquiária). Um total de 424 espécimes de crisopídeos foi coletado, sendo distribuídos em três espécies: Chrysoperla externa (98,1%), Ceraeochrysa cubana (1,7%) e Ceraeochrysa paraguaria (0,2%). Não houve diferença no número de adultos coletados em função dos diferentes cultivos, embora a análise de correlação evidencie que as rotações com poáceas favoreçam o aumento da sua abundância. A abundância dos crisopídeos foi influenciada pelo clima apenas no sistema de cafeeiros sombreados, sendo correlacionada negativamente com a temperatura média do ar e a com a precipitação pluvial acumulada.(AU)

The green lacewings (Chrysopidae) have been reported in natural ecosystems as well in agroecosystems, intercropping or monocropping. However, the knowledge on their behavior on different agroecosystems is scarce. The present work aimed to determine the diversity of green lacewing species and to evaluate the influence of different agricultural crops, as well as climate factors, on the abundance of these insects in an agroecologically-based organic production system. The study was conducted from September 2008 to August 2009, by performing weekly sampling of Chrysopidae adults in areas of the Integrated Production Agroecological System (SIPA) in Seropédica (RJ), each with one type of cropping system (corn-mucuna rotation/vegetable crops; shaded coffees and sugar cane/brachiaria pasture rotation). A total of 424 adult specimens were collected, belonging to three species: Chrysoperla externa (98.1%), Ceraeochrysa cubana (1.7%) and Ceraeochrysa paraguaria (0.2%). There were no differences on the number of green lacewing adults collected in the crops, although the correlation analysis showed that the crop rotations with grasses favor their abundance. The abundance of green lacewings was also influenced by the climate conditions only in the system of shaded coffees, being negatively correlated with mean air temperature and accumulated rainfall.(AU)
