Arisemus atlanticus Vilarinho, Araújo, Bravo & dos Santos sp. nov. and Arisemus benignoi Vilarinho, Araújo & Bravo sp. nov. are described from the Central Corridor of the Atlantic Forest. Currently, thirty-three species of the genus has been described from the Neotropical Region and only one from Brazil.

In this article we present the historical records of the Brazilian hawkmoths deposited in the Entomological Collection of the Museu de História Natural da Bahia (MHNBA-UFBA), including the historical Lepidoptera collection donated by Dr. Pedro de Araújo to the MHNBA-UFBA. The Sphingidae collection is composed of 243 specimens and represents 24 genera and 66 species. The historical collection consists of specimens captured between the years 1924 and 1934, and we also included to the collection specimens that were captured more recently, between 1982 and 2014. The subfamily Macroglossinae presented the greatest species richness and Smerinthinae the presented the least species richness. Of all of specimens in the collection, 151 came from São Paulo State (Brazil), 41 from Santa Catarina State, 50 from Bahia State and only one from Pernambuco State. Three topotypes were identified in the collection, namely: Eumorpha translineatus (Rothschild, 1895), Xylophanes crenulata Vaglia & Haxaire, 2009 and Xylophanes alineae Haxaire & Mielke, 2018.

Radish is a short cycle horticultural product from family Brassicaceae. Between the insects found on radish leaves, potato green aphid (Myzus persicae Sulzer) is one of the main pests of this culture, causing economic damage. Synthetic fertilizers used in conventional crops can promote changes in the pattern of amino acids in plants, leading to a higher insect damage. The source of fertilization is one of the factors that could influence in the incidence of pests. The objective of the study was to evaluate the incidence of potato green aphid and other pests on radish plants grown with different doses of organic fertilizer. The experiment was carried under semi-field conditions, in Fortaleza (Ceará State). A completely randomized design was used, with six replicates. The treatments consisted of five doses of organic compost (0; 45; 60; 75; 90 t.ha-1). For the population survey of pests and natural enemies, counts were made in three evaluations (7, 14 and 21 days after sowing). The counting data were subjected to deviance analysis using a generalized linear model (GLM). It was observed significant differences in the number of adults M. persicae in the treatments of 75 and 90 t.ha-1. Presence of leafminer (Lyriomiza sp.) was observed on plants without and with the lower doses of organic fertilizer. Even using organic fertilizers that promote a slower liberation of nutrients, high incidence of pests (Mainly M. persicae) was observed on radish plants.

The knowledge of host plants, distribution and economic importance of Lonchaeidae is scarce in Latin America. We have recovered specimens of Lonchaeidae from most fruit samples containing specimens of Tephritidae. The compilation of information is essential to determine the diversity of species and the relationship with their hosts. In addition to the list of records based on early publications, we add unpublished data of Lonchaeids recovered from plant samples collected in the Instituto Biológico, São Paulo, Brazil. In total, 18 species of Lonchaeidae, belonging to the genera Dasiops, Lonchaea and Neosilba were registered in São Paulo, and associated with 111 host plant species and 27 botanical families. New records are listed and geographical distribution is available by specific maps.

Some conservation units in Brazil border urban areas, like the Catolé and Fernão Velho Environmental Protection Area (EPA) in the State of Alagoas. In urban areas, there is the habit of cultivating plants for landscape purposes, and Syagrus coronata (Martius) Beccari (Arecaceae), “Licuri” or “Ouricuri”, is a palm tree commonly used in ornamentation; a native species from Caatinga and Atlantic Forest biomes widely explored through time. Some insects have part of their development associated with plants, and Pachymerus nucleorum Fabricius (Coleoptera: Chrysomelidae: Bruchinae) has a close connection with some Arecaceae. Females usually lay eggs on the surface of fallen fruits and the immatures feed on the seed under the drupe endocarp; the larvae, even protected by the hard surface could be preyed by skilled parasitoid wasps. Here, the record of a tritrophic relationship between S. coronata, P. nucleorum, and a wasp of the genus Heterospilus (Hymenoptera: Braconidae) in an urbanized region of Alagoas, close to a remnant of Atlantic Forest of the Catolé and Fernão Velho EPA is communicated. Fruits were collected from the soil surface under the canopy of Licuri palms in the “Universidade Federal de Alagoas” A. C. Simões Campus and transported for laboratory monitoring. Either adults of Heterospilus parasitoid wasps and P. nucleorum beetles from some fruits were recorded. The specimens of S. coronata had seeds preyed upon by P. nucleorum close to a remnant of the Atlantic Forest. The record of a tritrophic relationship involving Heterospilus seems to indicate the tenacity of natural biological control.

The Mediterranean fruit fly Ceratitis capitata (Wiedemann) is a polyphagous pest adapted to tropical and subtropical climates, which are responsible for the highest share of fruit production. Fruit fly surveys are frequently done by installing traps at heights easily reached by the collector, between 1.5 and 2.5 meters. This study aims to inform fruit fly monitoring strategies by assessing two trap heights (around 2 m and 10 m) in four environments (agricultural and forest) at the “Luiz de Queiroz” Campus, Piracicaba, São Paulo state, Brazil. Each collection environment was considered a block, and eight multilure traps were installed at each of the two heights on four plants per block. A generalized linear model was used for non-normal data with negative binomial distribution to compare the abundance of C. capitata between trap heights and areas. The higher traps, positioned at around 10 m, collected significantly more specimens of C. capitata than those at approximately 2 m in height. The Mediterranean fruit fly was more frequent in the cultivated environments and areas with human activity than in natural areas.

Brazil is one of the most diverse countries in the world, hosting more than 250 known species of mantids (Mantodea). Studying natural history collections is crucial to identify, describe new taxa and solve taxonomic issues, improving the knowledge about the biodiversity. Here we document the transference of the mantids collection from the Entomological Collection of Instituto Butantan (São Paulo, Brazil) to the Museu Nacional (Rio de Janeiro, Brazil) and provide a morphological assessment on the 33 transferred mantids. We recognized 13 genera and 12 species, with diversified distribution in Brazil, although 6 specimens from 4 genera could not be identified at a specific level. The transference of this collection starts a new phase of restructuration and recognition of the Medical Entomology scope of the donor collection, aside from helping the rebuilt of the Entomological Collection of the Museu Nacional, lost in the 2018 fire, and allowing further researches within the group.

A new species of Euplocania belonging in the Marginata species group, collected in an area of the Atlantic Rainforest in Brazilian states of Bahia is described and illustrated. It differs from all the other species in the Marginata species group in details of the hypandrium and phallosome. This is the first record of a species in the Marginata species group for the Atlantic Rainforest biome and the first record of a Euplocania species for Brazilian states of Bahia.

We characterize the population dynamics of pests and beneficial organisms in strawberries to assess the impact of two meteorological factors (temperature and precipitation) and define the most appropriate method for monitoring insects in strawberries crop. Population dynamics were monitored weekly using the plant beat method and Möericke traps in Albion strawberries. Measurements were taken in organic strawberry farms over two growing seasons, from March 26, 2010 to August 23, 2010 (first season - 2009/2010) and from October 4, 2010 to March 21, 2011 (second season - 2009/2010) in the municipality of Pinhais, Paraná state, southern Brazil (25º25'S; 49º08'W). We collected a total of 7,971 pests and 1,987 beneficial organisms. The most abundant pests were Chaetosiphon fragaefolii (Cockerell) (Hemiptera: Aphididae) in the first growing season and Tetranychus urticae (Koch) (Acari: Tetranychidae) in the second. Beneficial organisms from Acari, Araneae, and Hymenoptera parasitoids predominated in both seasons. Temperature and precipitation were the the primary climatic factor associated with the population variation of aphids. Populations of C. fragaefolii grew when the temperature was between 16°C and 25ºC. We found that plant beat was the fastest and most suitable method for strawberry pests monitoring since it captured insects that were effectively colonizing the plants. This study contributes to a better understanding of the entomofauna associated with cultivation of organic strawberry.

There are different methodologies used to make an inventory of social wasps. In general, these methods are divided into active search and passive collections. Each method has a different performance, depending on the environment in which the collection is being carried out. Thus, the choice for the proper methodology according to the study area will impact the success of sampled species. This study aimed to evaluate the performance of sampling methodologies for social wasps (active search and bait traps) in different phytophysiognomies (Regenerating Cerrado, “Cerradão”, Restored Forest, Semideciduous Forest and Riparian Forest) in the state of São Paulo, Southeastern Brazil. The active search sampled a greater number of species, with the exception of the Regenerating Cerrado. Regarding abundance, the active search was also more efficient, except in “Cerradão”, where there was no difference between the methods, and in Regenerating Cerrado, where the traps sampled a higher number of individuals. The fact that none of the methods collected all the sampled species indicates that it is appropriate to use more than one collection method in order to obtain a sampling closer to the true richness of the studied sites.
