Global sustainability rests on a myriad of benefits provided by natural ecosystems that support human livelihoods and well-being, from biodiversity persistence to climate regulation. The undeniable importance conserving tropical forests has drawn most the conservation spotlight towards it. However, open such as Brazilian Campo Rupestre (rupestrian grassland), have been historically overlooked despite their high diversity key associated ecosystem services. We highlight major current threats...
The potential of the synthetic major component T. absoluta (Meyrick) sex pheromone for mating disruption was studied in small plots (0.01 hectares) with fresh-market tomato crop. effects application 3E,8Z,11Z-14:Ac (from 0 to 80 g a.i./ha) were assessed on male orientation baited traps, cages and plant damage. highest levels interruption (60-90%) found treated 35 50 g/ha pheromone. However, no treatment capable significantly reducing percentage mined leaflets or bored fruits frequency...
Atta nest densities in six undisturbed primary rain forest ecosystems the Orinoco-Amazon basin have been estimated. The only species encountered was cephalotes which occurred at a maximal density of 0.045 nests per ha. Three possible explanations for these low contrast to those found disturbed habitats are discussed. number clearings is proposed be limiting factor colonization new sites by A. cephalotes.
Abstract Sampling techniques currently used to determine control measures for the Coffee Berry-borer (CBB) are time-consuming and allow grower only a small window of opportunity select other options. Experiments were conducted in four coffee fields between 2005 2007 using IAPAR® traps that baited with ethanol methanol (1 : 3 ratio) benzaldehyde at 1% volume, test correlation number captured adults infestation levels CBB, action threshold level. For this study, density 20 traps/ha was each...
Summary The egg parasitoid, Telenomus podisi , was shown to recognize its host, Euschistus heros through both chemical and physical cues. These were determined in short‐range bioassays. cues comprised fertile infertile host eggs, extracts, crude extracts of adult males females successive dilutions the synthetic racemic mixture methyl 2,6,10‐trimethyltridecanoate, a male‐produced pheromone E. . Some treatments used induced selection process T. recognition behaviour, indicating consistent...
Estudou-se a biologia de Euschistus heros (F.) (Heteroptera: Pentatomidae) em laboratório sob 24±0,5ºC, 70±10% UR e fotofase 14 h. O tempo médio desenvolvimento até adulto foi 38,6 d, sendo o 2º estádio ninfal, maior índice mortalidade (10,4%). A longevidade E. variou acordo com sexo atividade sexual. Machos fêmeas atingiram maturidade sexual 11,4 11,2 respectivamente. para colocação posturas, após primeiro acasalamento, 9,1 d fêmeas, que acasalaram uma única vez, 13,9 dias várias vezes...
The major sex attractant emitted by Scrobipalpuloides absoluta females is shown to be (3E,8Z,11Z)-3,8,11-tetradecatrien-1-yl acetate a novel strategy involving the random reduction of double bonds, followed methylthiolation reduced products. Each female gland contains ca. 1-5 ng this pheromone. This triene ester, synthesized stereospecific procedure, shows spectral and gas chromatographic properties identical those natural substance. In field tests wind tunnel bioassays, synthetic ester was...
This study determined the effects of gallium-aluminum-arsenide laser (GaAlAs), gallium-arsenide (GaAs) and Dersani healing ointment on skin wounds in Wistar rats. The parameters analyzed were: type I III collagen fiber concentrations as well rate wound closure. Five wounds, 12 mm diameter, were made animals' backs. depth surgical incision was controlled by removing epithelial tissue until dorsal muscular fascia exposed. animals anesthetized with ketamine xylazine via intraperitoneal...
Summary The responses of the grass‐cutting ants Atta bisphaerica (Forel) and capiguara (Gonçalves) to main components their alarm pheromones were examined in simple field bioassays. Both species react most strongly 4‐methyl‐3‐heptanone, which causes full range behaviour a large increase number individuals near sources. In later experiments with A. , this was found be due primarily attraction, some arrestment also occurring. ant response 4‐methyl‐3‐heptanone compared that crushed heads whole...
Abstract 1 Despite the importance of Leucoptera coffeella (Guérin‐Mèneville) in coffee production worldwide, there is a lack information on its reproduction. This knowledge will help mass rearing, and support development behavioural control techniques for this insect. The present study determined effects delayed mating previous matings male L. fecundity, egg viability frequency female remating. 2 highest levels fecundity were obtained from 1–3‐day‐old females. When females mated at 5 days...
