Biologia de montandoniola confusa streito & matocq (hemiptera: Anthocoridae) em presa natural e alternativa.

O percevejo Montandoniola confusa Streito & Matocq tem sido citado como sendo o principal predador de Gynaikothrips ficorum Marchal, espécie monófaga que induz galhas em plantas de Ficus, como a espécie Ficus microcarpa L.f. (Moraceae). Estas espécies de fícus têm sido introduzidas em diversas partes do mundo, incluindo o Brasil, para utilização no paisagismo. Assim, este trabalho estudou o desenvolvimento e a reprodução do percevejo-predador usando o tripes, sua presa natural, comparado com ovos de Anagasta kuehniella (Zeller) e de Sitotroga cerealella Oliver, empregados como presas alternativas para a sua multiplicação. Título em inglês: Biology of montandoniola confusa streito & matocq (hemiptera: Anthocoridae) using natural and alternative prey

First record of Tenuipalpus uvae De Leon, 1962 (Acari: Tenuipalpidae) in Brazil.

This is the first record of Tenuipalpus uvae De Leon (Tenuipalpidae) in Brazil. Specimens were collected from Spondias mombin L. (Anacardiaceae) in the states of Amapá (northern Brazil) and Pernambuco (northeast)

Detection of coffee ringspot virus (CoRSV) in the mite vector by RT-qPCR.

The mite Brevipalpus phoenicis (Geijskes, 1939) (Acari: Tenuipalpidae) is responsible for the transmission of coffee ringspot. There is a great interest in the study of Brevipalpus transmitted viruses (BrTVs), and the interaction between them, their vectors and hosts. Electron microscopy analyses suggest that CoRSV replicates in the mite tissue, what would characterize a persistent propagative virus-vector relationship. This study aimed to establish a transcriptase quantitative polymerase chain reaction (RT-qPCR) method to evaluate and compare the replication capacity of the virus in the vector. Total RNA was extracted from a sample of 100 mites reared in symptomatic plants for CoRSV using two different methods: CTAB and Nucleo Spin RNA XS Kit (Macherey-Nagel) and quantified in a NanoDrop 8000 (Thermo Scientific).Abstract 10

Bacilli rhizobacteria as biostimulants of growth and production of sesame cultivars under water deficit.

A strategy using bacilli was adopted aiming to investigate the mitigation of the effects of water deficit in sesame. An experiment was carried out in a greenhouse with 2 sesame cultivars (BRS Seda and BRS Anahí) and 4 inoculants (pant001, ESA 13, ESA 402, and ESA 441). On the 30th day of the cycle, irrigation was suspended for eight days, and the plants were subjected to physiological analysis using an infrared gas analyzer (IRGA). On the 8th day of water suspension, leaves were collected for analysis: superoxide dismutase, catalase, ascorbate peroxidase, proline, nitrogen, chlorophyll, and carotenoids. At the end of the crop cycle, data on biomass and vegetative growth characteristics were collected. Data were submitted for variance analysis and comparison of means by the Tukey and Shapiro–Wilk tests. A positive effect of inoculants was observed for all characteristics evaluated, contributing to improvements in plant physiology, induction of biochemical responses, vegetative development, and productivity. ESA 13 established better interaction with the BRS Anahí cultivar and ESA 402 with BRS Seda, with an increase of 49% and 34%, respectively, for the mass of one thousand seeds. Thus, biological indicators are identified regarding the potential of inoculants for application in sesame cultivation
