RESUMEN
Investigation of the diversity of lacewings (Neuroptera: Chrysopidae) is crucial in agricultural systems, as these insects are important predators of many pest species. Recent studies have shown that height influences the abundance and richness of insects. Information on these factors is scarce for species of Chrysopidae at different heights in agricultural and forest environments. This study aimed to evaluate the influence of height on the abundance and richness of green lacewings in an anthropically modified environment. Multilure traps baited with putrescine and ammonium acetate were placed in four areas of the "Luiz de Queiroz" Campus (Piracicaba, São Paulo State, Brazil) at two heights (2 and 10 m) from April 2019 to March 2020. Species captured in traps hung at 2 and 10 m above the ground surface were studied with the faunistic analysis ANAFAU, using ecological parameters and diversity indices. The similarity between the species was measured using the Morisita-Horn coefficient. Thirteen species of Chrysopidae were captured, and more species and specimens of green lacewings were collected with the traps at 2 m than at 10 m, that is, height influenced the abundance and richness of the lacewing species. Leucochrysa (Nodita) cruentata (Schneider) was predominant in most areas studied. The highest diversity and abundance of green lacewings was observed on Areão farm in trap at 2 m height. However, Ceraeochrysa claveri (Navás) and Ce. everes (Banks) showed a more similar ecological pattern. Multilure traps baited with putrescine and ammonium acetate were effective in sampling green lacewings, mainly at 2 m height.

Studies on the diversity of Anastrepha species have been conducted mainly in agricultural orchards due to the economic importance of this insect group, consequently, research on fruit flies in undisturbed environments is scarce. Moreover, very few studies have investigated the diversity of fruit flies in urban areas, where fruit flies survive under native or exotic hosts. Thus, to understand the diversity of Anastrepha species in an environment with different anthropization degrees, surveys were carried out in four areas of the "Luiz de Queiroz" campus, in Piracicaba, São Paulo State (Brazil), using Multilure traps with putrescine and ammonium acetate for 12 months. The software R 3.6.3 was used to characterize the fruit fly community and the faunistic analysis was carried out using the ANAFAU program. The analysis of species richness and total abundance of fruit flies among the sites was carried out using the rarefaction method and adjustment to the generalized linear model (GLM) using the Poisson distribution, respectively. We collected 1,080 females and 14 species of Anastrepha in the four sampled sites. Anastrepha fraterculus and A. obliqua were the predominant species (behavioral patterns). Similar to agricultural sites, A. fraterculus and A. obliqua also show a predominant occurrence in urban environments.

This is the first record of Melanoloma viatrix Hendel as well as in its host (pineapple) in Brazil. Previously, M. viatrix had been found in pineapple plantations in Peru, Colombia, Venezuela, and Ecuador. In Brazil, this fly was initially reported in pineapple purchased from a commercial establishment in the municipality of Porto Grande, Amapá State, in 2020. Subsequently, M. viatrix was found in a commercial pineapple plantation, Ananas comosus (L.) Merr. cv. Pérola, also in Porto Grande, Amapá State. In the pineapple samples, 2,320 specimens of M. viatrix were collected on a single day on that rural property (approximately 2 ha). The larvae open galleries in the pulp that cause the pineapple to rot, making it unviable for consumption and commercial sale. This communication aims to alert phytosanitary authorities of the need to establish control strategies to prevent the spread of the pineapple fly to other states in Brazil.

The history of the taxonomy of Trichogramma parasitoid wasps can be divided into two phases. In the first phase, species identifications were based on external morphological characters; however, these identifications proved to be confusing and inaccurate. In the second phase, starting in the 1970s, taxa were identified based on charcteristics of the male genital capsule , leading to a major advance in Trichogramma taxonomy. The history of Trichogramma taxonomy in Brazil is recent and mainly related to species that parasitize agricultural pests. In Brazil, the first phase of Trichogramma taxonomy occurred in the 1960s, while the second phase occurred from the 1980s onward. In this second phase, Trichogramma taxonomy progressed significantly and knowledge of Trichogramma diversity as well as associations with lepidopteran pests improved markedly in Brazil as well as worldwide. The last five decades have seen significant progress in studies in Brazil, with taxonomy evolving from identifications based exclusively on morphological characters to integrative taxonomy, encompassing biology (crosses) and morphometry. This historical outline presents the phases of Trichogramma taxonomy in Brazil, addressing the hurdles encountered in the first descriptions, erroneous records of the species, and species descriptions since the 1980s. We highlight the importance of accurately identifying Trichogramma taxa for their use in biological control, as well as species diversity and associations with lepidopteran hosts.

Damage from Sinoxylon anale Lesne, a woodboring beetle not previously known to be established in Brazil, was observed in young jabuticaba trees (Plinia cauliflora, Myrtaceae) in a nursery in the municipality of Laranjal Paulista, state of São Paulo. We immediately advised MAPA ("Ministério da Agricultura, Pecuária e Abastecimento") and collected samples from the nursery and from different hosts in nearby areas, to identify the specimens and investigate the dynamics of the infestation in the jabuticaba trees. Sinoxylon anale was also collected in ethanol-baited and ultraviolet-light traps and in dry branches of the native species pau-jacaré (Piptadenia gonoacantha, Fabaceae) and inga (Inga vera, Fabaceae), and the exotic pau-d'água (Dracaena fragrans, Asparagaceae) in the municipality of Piracicaba, state of São Paulo. These collections established that S. anale larvae and adults develop in dead branches of four new host plants. Taxonomic studies using morphological parameters and DNA barcoding confirmed the identification of S. anale. An illustrated key to the three Sinoxylon species now recorded in Brazil is provided, and the COI gene sequences have been made available in a public database. Sinoxylon anale probably attacked the young jabuticaba trees after they were killed by larvae of long-horned beetles (Cerambycidae). So far, S. anale has been found established only in two locations in the same area of the state of São Paulo.

Biological control and taxonomy are continuously developing fields with remarkable impacts on society. At least 80 years of literature have documented this relationship, which remains essentially the same in its mutualistic nature, as well as in its major challenges. From the perspective of Brazilian taxonomists, we discuss the impacts of important scientific and social developments that directly affect research in these areas, posing new challenges for this lasting relationship. The increasing restrictions and concerns regarding the international transit of organisms require improvements in research related to risk assessment for exotic biological control agents and also stimulate prospecting within the native biota. In our view, this is a positive situation that can foster a closer relationship between taxonomists and applied entomologists, as well as local surveys and taxonomic studies that are necessary before new programs and agents can be implemented. We discuss the essential role of molecular biology in this context, as an iconic example of the synergy between applied sciences and natural history. As our society comes to need safer and more sustainable solutions for food security and the biodiversity crisis, scientific progress will build upon this integration, where biological control and taxonomy play an essential role.

The hymenopteran parasitoids of pest species of Tephritidae in Brazil are best known by their most prominent species, members of Braconidae and Figitidae. Species in the less-studied families Diapriidae, Eulophidae and Pteromalidae, which are mostly pupal parasitoids, have been largely neglected and the literature on these groups is sparse and scattered. Therefore, their importance as natural enemies of fruit flies is likely underestimated. Here, we present a parasitoid-host-plant checklist of all diapriids, eulophids and pteromalids that parasitize fruit flies of economic importance in Brazil, namely Anastrepha species and Ceratitis capitata. A compilation of information of the seven species of these parasitoids occurring in Brazil-Coptera haywardi Loiácono and Trichopria anastrephae Lima (Diapriidae), Tetrastichus giffardianus Silvestri (Eulophidae), Pachycrepoideus vindemmiae (Rondani), Spalangia endius Walker, S. gemina Boucek and S. simplex Perkins (Pteromalidae)-including their taxonomic status, general biology, and potential as biocontrol agents, is presented. Additionally, we provide an illustrated key to species, aiming to highlight key morphological features and facilitate identification at species level, stimulating future research on these groups.

This study aimed to know the species of frugivorous flies (Tephritidae and Lonchaeidae) and their parasitoids associated with fruits in home orchards. It was conducted in the Gurgueia Valley, municipality of Bom Jesus, Piauí, Brazil. Fruit collection was carried out from April to December 2016. A total of 959 fruits (12 kg) belonging to seven fruit species were sampled, such as acerola (Malpighia glabra), carambola (Averrhoa carambola), lime (Citrus aurantifolia), balsam pear (Momordica charantia), cherry of the Rio Grande (Eugenia involucrata), umbu-cajá (Spondias bahiensis), and purple mombin (Spondias purpurea). Only three among these species (acerola, umbu-cajá, and purple mombin) were host, with 2,770 frugivorous flies. Umbu-cajá hosted 316 specimens of Anastrepha obliqua, from which puparia have emerged 84 specimens of Opius bellus and four of Pachycrepoideus vindemmiae. Purple mombin hosted Ceratitis capitata (2,384 specimens), Neosilba pendula (69 specimens), and Anastrepha sp. (one male). Eleven specimens of Tetrastichus giffardianus emerged from the puparia of C. capitata. Acerola hosted only one female of C. capitata and six specimens of N. pendula. Ceratitis capitata and N. pendula were recorded for the first-time infesting fruits of purple mombin in Piauí. Tetrastichus giffardianus parasitizing C. capitata in purple mombin was first recorded in the state of Piauí. Pachycrepoideus vindemmiae is a new record in A. obliqua in umbu-cajá in Brazil.
