The Sterile Insect Technique: Success and Perspectives in the Neotropics Neotrop. Entomol. (IF 1.33) Pub Date : 2020-10-28 D. Pérez-Staples, F. Díaz-Fleischer, P. Montoya
The sterile insect technique (SIT), an environmentally friendly means of control, is currently used against plant, animal, and human pests under the area-wide integrated pest management. It consists in the mass production, sterilization, and release of insects in an affected area where sterile males mate with wild females leading to no reproduction. Here, we review SIT in the Neotropics and focus on

How Habitat Filtering Can Affect Taxonomic and Functional Composition of Aquatic Insect Communities in Small Amazonian Streams. Neotrop. Entomol. (IF 1.33) Pub Date : 2020-05-21 G Nicacio,E J Cunha,N Hamada,L Juen
Responses in taxonomic and functional composition of communities were analysed in small Amazonian streams at the small and large scale (habitat patches, river segment scale, and catchment scale). We hypothesised that similar responses in community structure to local environmental factors were a correlation between taxonomic and functional composition. To evaluate the response of taxonomic composition

Two new species of Collembola (Arthropoda: Hexapoda) from Minas Gerais, Brazil. Neotrop. Entomol. (IF 1.33) Pub Date : 2020-05-12 J V L C Oliveira,A S Ferreira,D Zeppelini
Two new species of Collembola are described, full body chaetotaxy is given. Ptenothrix dalii sp. nov. and Seira pietata sp. nov. were originally found in metalogenic areas covered with transitional vegetation of savanna and forest in Minas Gerais, Southeastern Brazil. Ptenothrix dalii sp. nov. is part of the “gracilis-group” of species, with large, blunt macrochaetae on head and body. Seira pietata

Comments on the Classification of Neotropical Scionini (Tabanidae) with a Description of a New Genus. Neotrop. Entomol. (IF 1.33) Pub Date : 2020-05-12 T K Krolow,A L Henriques,C R González,S S Nihei
The classification of the Tabanidae had remained stable over the last 60 years after Mackerras proposed a great revolution in the arrangement of the family. Recently, some new proposals based on molecular data have once again changed the classification of the family, mainly with a focus on the tribe Scionini. The present paper introduces a critical analysis based on the taxonomical view of the recent

Urbanization Affects Composition but Not Richness of Flower Visitors in the Yungas of Argentina. Neotrop. Entomol. (IF 1.33) Pub Date : 2020-05-03 A A Amado De Santis,N P Chacoff
Urban areas represent a spatially small impact in relation to other land-uses such as livestock and agriculture, but they undergo rapid changes. Such changes involve their size, shape, interconnectivity, and composition of natural patches. Habitat loss generated by urbanization affects the diversity and abundance of bees and other flower visitors in many sites. In general, the presence of urban areas

Induced Tomato Resistance Against Bemisia tabaci Triggered by Salicylic Acid, β-Aminobutyric Acid, and Trichoderma. Neotrop. Entomol. (IF 1.33) Pub Date : 2020-05-02 F Jafarbeigi,M A Samih,H Alaei,H Shirani
Bemisia tabaci Gennadius (Hemiptera: Aleyrodidae) biotype B is a key pest of Solanum lycopersicum L. (Solanaceae) throughout the world. In this study, we examined the induction of resistance on tomato plants treated with SA, BABA, and Trichoderma either individually or in combination against B. tabaci biotype B through the assessment of some biological and behavioral aspects of this insect pest. Also

Entomopathogenic Viruses in the Neotropics: Current Status and Recently Discovered Species. Neotrop. Entomol. (IF 1.33) Pub Date : 2020-05-01 D R Sosa-Gómez,F S Morgado,R F T Corrêa,L A Silva,D M P Ardisson-Araújo,B M P Rodrigues,E E Oliveira,R W S Aguiar,B M Ribeiro
The market for biological control of insect pests in the world and in Brazil has grown in recent years due to the unwanted ecological and human health impacts of chemical insecticides. Therefore, research on biological control agents for pest management has also increased. For instance, insect viruses have been used to protect crops and forests around the world for decades. Among insect viruses, the

A New Species of Moth Lacewing from the Mesoamerican Genus Adamsiana Penny 1996 (Neuroptera: Ithonidae). Neotrop. Entomol. (IF 1.33) Pub Date : 2020-04-29 A Ardila-Camacho,R Castillo-Argaez,J I Martínez
The poorly studied Mesoamerican genus Adamsiana Penny, 1996 (Neuroptera: Ithonidae) was considered monotypic for more than 20 years, containing only Adamsiana curoei Penny. However, a second species was recently discovered in the southern region of Guatemala and is described here as Adamsiana alux Ardila-Camacho, Castillo-Argaez & Martinez, sp. nov. A key to the Adamsiana species and a list of the

A Spinosad-Based Formulation Reduces the Survival and Alters the Behavior of the Stingless Bee Plebeia lucii. Neotrop. Entomol. (IF 1.33) Pub Date : 2020-04-28 R D Marques,M A P Lima,R D Marques,R C Bernardes
The decline in bee populations worldwide has been associated with the use of pesticides in crop systems where these insects forage. The use of biopesticides, like spinosad, is preferred as an alternative method to control pests, because it is considered safer to non-target insects. In this study, we evaluated the lethal and sublethal effects of the spinosad-based formulation Tracer® on foragers of

Revisional Notes on the Cloud Forest Butterfly Genus Oxeoschistus Butler in Central America (Lepidoptera: Nymphalidae: Satyrinae). Neotrop. Entomol. (IF 1.33) Pub Date : 2020-03-14 T W Pyrcz,A Zubek,P Boyer,I Nakamura,B Wacławik,K Florczyk
So far, six species of Oxeoschistus Butler, including its junior synonym Dioriste Thieme, were listed from Central America, with five of them from Costa Rica alone, which appears to represent the highest regional diversity of this Neotropical montane butterfly genus. Our research based on field work, morphological studies and barcode analysis proved that one record is a misunderstanding perpetuated

Effects of Climate Variability on Queen Production and Pollen Preferences of Neotropical Bumblebee Bombus atratus in a High Andean Suburban Condition. Neotrop. Entomol. (IF 1.33) Pub Date : 2020-03-11 D Riaño-Jiménez,M Guerrero,P Alarcón,J R Cure
Bombus atratus Franklin is a widely distributed bumblebee of South America. In Colombia, this species is recognized for its ability to adapt to highly disturbed habitats. However, knowledge of its ecology is poorly known, in particular conditions to ensure the long-term conservation of its populations. Identification of pollen resources is an important issue that could be used as a tool to manage and

Diversity of Floral Visitors in Apple Orchards: Influence on Fruit Characteristics Depends on Apple Cultivar. Neotrop. Entomol. (IF 1.33) Pub Date : 2020-03-11 P Nunes-Silva,S Witter,J M da Rosa,R Halinski,L M Schlemmer,C J Arioli,J D Ramos,M Botton,B Blochtein
Most cultivars of apple trees are highly dependent on insects for successful pollination and fruit production. In this study, we evaluated the insect diversity in apple orchards of southern Brazil and verified whether or not there is a relationship between the diversity of insect visitors and the characteristics (weight, seed number, and symmetry) of the fruits of ‘Fuji’ and ‘Gala’ apples produced
