Knowledge on biodiversity is fundamental for conservation strategies. The Brazilian Pampa region, located in subtropical southern Brazil, neglected terms of conservation, and knowledge its fragmented. We aim to answer the question: how many, which, species occur Pampa? In a collaborative effort, we built lists plants, animals, bacteria, fungi that Pampa. included information distribution patterns, main habitat types, status. Our study resulted referenced totaling 12,503 (12,854 taxa, when...
Three Cosmolaelaps species were found in surveys recently conducted the Pampa biome southern Brazil. One of these is a new here described as pampaensis sp. nov. In same surveys, heteromorphic male specimens guttulatus (Karg, 1978) collected. A key for identification reported from Brazil provided.
ABSTRACT Two-spotted spider mite, Tetranychus urticae Koch, is considered the main pest in strawberry crop. The control of this species hampered by low efficiency products currently used, occurrence populations resistant to acaricides and high reproductive potential pest. This leads use pesticides increased agrochemical residues fruits. cultivars ideal method because they maintain mite below levels economic damage, minimize environmental impact at no extra cost farmer, serve as an auxiliary...
O objetivo deste trabalho foi avaliar a eficiência de controle e os efeitos adversos dois produtos à base nim Azamax® (Azadiractina A/B 12g/L) Neemseto® A/B, Nimbina Salanina 2,389 g/L) sobre o ácaro-rajado Tetranychus urticae predadores Phytoseiulus macropilis Neoseiulus californicus em laboratório. Para ácaro-rajado, foram consideradas as variáveis mortalidade, fecundidade, efeito ovicida persistência biológica, enquanto para fitoseídeos consideraram-se mortalidade fecundidade. A máxima...
A new species of Binodacarus Castilho & Moraes, aceguensis sp. nov., is described based on morphology adult females and males collected from soil in a survey carried out the southern Brazil 2012–2013, raising to two number known this genus. The genus rediagnosed accommodate morphological features species.
ABSTRACT: The spotted spider mite, Tetranychus urticae (Koch, 1836), is one of the most important pests strawberry production systems worldwide. Because plant resistance an integrated management strategy, present study investigated effects 12 genotypes on biological characteristics this pest under laboratory conditions (25 ± 2 °C and RH 60 10%; 12:12-hour photophase). experiment was carried using treatments (genotypes), divided into 20 replications each, in a completely randomized design....
Bradysia species are major insect pests of protected production systems, including strawberry crops in semi-hydroponic systems. In Brazil, its management is difficult due to the absence available effective pesticides. The aim this study was evaluate predatory efficiency two mites (Stratiolaelaps scimitus and Cosmolaelaps brevistilis) under laboratory conditions. experiments were conducted at 25 ± 1ºC, 75 10% RH, dark. first bioassay predation potential each mite species, one female per...
ABSTRACT: The diversity of edaphic mites in Brazilian natural environments is little known, especially the Pampa biome, southern region Brazil. objective this study was to evaluate and abundance fauna mesostigmatid a biome state Rio Grande do Sul. Soil samples were collected municipality Aceguá, 2012 2013. Mites extracted using Berlese-Tullgren modified funnels. In total, 1900 collected, representing 44 species from 23 genera 10 families. most abundant families Rhodacaridae, Ologamasidae...
ABSTRACT: The use of plant resistance acts by intervening in the herbivore-host relationship, through morphological, physical or chemical factors plant. This study evaluated oviposition and foliar consumption Chrysodeixis includens (Walker [1858]) soybean genotypes, free- no-choice tests, correlating them with factors, density size trichomes. experiments were carried out laboratory (25 ± 2 °C; RH= 70 10%; photoperiod 14h) using five cultivars (BRS 391, BRS 6203 RR, BMX Valente Tec Irga 6070...
ABSTRACT: Soilless cultivation of strawberry is in expansion Brazil due to factors like the reduction phytosanitary problems and possibility extending crop period, as well ergonometric facility for management culture. However, black fungus gnats (Sciaridae, Diptera) are ubiquitous pests greenhouse production system, causing direct indirect damage plants. ThIS study evaluated occurrence species semi-hydroponic identify species, describe symptoms infested The research was developed commercial...
Lycoriella species (Sciaridae) are responsible for significant economic losses in greenhouse production (e.g. mushrooms, strawberry, and nurseries). Current distributions of the genus restricted to cold-climate countries. Three particular concern view their ability invade across Northern Hemisphere. We used ecological niche models determine potential range expansion under climate change future scenarios (RCP 4.5 RCP 8.5) these Lycoriella. Stable suitability was a dominant theme species;...
Bacillus thuringiensis (Bt) Berliner has potential for use in insect management. Its can be an alternative the management of Bradysia aff. ocellaris (Comstock), considered one main strawberry pests a soilless system. Therefore, objective this work was to evaluate toxicity different bacteria on B. laboratory and greenhouse bioassays. The following isolates were used experiments: circulans (Bc), var. oswaldo cruzi (Bto) or israelensis (Bti) kurstaki (Btk) In laboratory, larvae showed high...
Laelaspis loeckii Duarte Moreira sp. nov. is described based on the morphology of adult females and males collected from soil in a survey carried out southern Brazil, temperate Pampa biome. This first species this genus country. A key to that have so far been reported Western Hemisphere provided.
Black fungus gnat larvae are one of the primary insect pests in greenhouse and nursery crops, Bradysia ocellaris (Comstock) (Diptera: Sciaridae) is common pest species. This difficult to control Brazil because absence registered insecticides. The aim this work was evaluate effects some insecticides on B. larvae. We also verified that growth regulator novaluron caused deformation ocellaris. Of evaluated, malationa, thiamethoxam showed high mortality rate (96 86 % respectively). Further,...
