Effectiveness of Biopesticide Derived FromCassia Spectabilis and Nicotiana Tabacum Leaves Against the Main Insect Pests of Coffee and Its Effect on Other Arthropods

An experiment on the effectiveness of biopesticide made of ramayana (Cassia spectabilis) and tobacco leaves (Nicotiana tabacum) it called as Casnic, on Hypothenemus hampeiand Planococcus citriand its effect on the arthropods population fauna in coffee plantation had been conducted in Pest Laboratory of Indonesian Coffee and Cocoa Researh Institute and Bangelan Plantation in Malang. The treatment consisted of three level concentrations of botanical pesticide(15 ml, 30 ml, and 60 ml/lof water), Beauveria bassiana(at a dose 100 g spore per ha), metidation spraying (2 ml formulation per litre of water) and two control treatments (with and without soap). The field experiment was arranged in randomized complete block design (RCBD) with four replications. The results showed that botanical pesticide at the concentration of 30.0 ml stock solution per litre of water and applied four times with monthly interval was effective in controlling coffee berry borer (Hypothenemus hampei) and coffee mealy bug (Planococcus citri). The effectiveness was not significantly different compared to metidation and Beauveria bassianaat the dose of 0.8 l and 100 g formulation per ha per application. Application of the botanical pesticide did not show negative effect on the usefull predatory insects and other arthropods population in coffee ecosystem

Distribution Pattern of Coffee Berry Borer (Hypothenemus Hampei) on Arabica and Robusta Coffee

Coffee berry borer [CBB, Hypothenemus hampei (Ferr.)] is the main pest on coffee causing a significant losses. Distribution pattern of the pest is not known deeply until now, especially in Indonesia. The data of distribution pattern of pest is very important in constructing the strategy of integrated pest management, especially to determine a sampling method for monitoring of the pest. This experiment aimed to reveal the distribution pattern of CBB both spatially and vertically. The experiment was conducted on Arabica and Robusta coffee, located in Kalibendo estate in Banyuwangi East Java. A plot with 400 (20 x 20) of coffee trees were observed for infestation and population of CBB, at four branches on south, north, east and west directions for each tree. Collected data were analyzed to obtain the value of mean, variance (=s2), variance/mean relationship (=I), index of Morisita (=Iδ), coefficient of Green (=Cx) and k exponent of Negative Binomial. Results of the experiment revealed that spatial distribution pattern of CBB, both on Arabica an Robusta coffee, as well as for infestation and population parameters, was fit with aggregated or clumped distribution. For vertical distribution, it inclined that CBB infestation and population in the lower part of coffee tree was higher than in central and upper part of coffee tree. Plenty of infested coffee berries leaved on soil surface may result in higher infestation and population in the lower part

Use of Trapping for Controlling of Coffee Berry Borer (Hypothenemus Hampei)

Studies on the field trapping of coffee berry borer (CBB, Hypothenemus hampei) have been conducted to evaluate trap color, trap design and lures (attractant substances). The trials were conducted in a Robusta coffee plantation in East Java during August to December 2004. The trap color evaluated were red, orange, yellow, green and blue, set up in the coffee plantation using a four funnels trap. The traps installed on wood poles at a height of 175 cm above ground and placed among coffee trees. Observations were conducted every day for a week. Result of the study showed that the red and blue color traps captured CBB significantly higher than the others. During a week, the red color captured 1694 CBB adults while the blue one captured 1619 CBB adults. Peak number of captured CBB of the red and blue trapping occurred on the third day with the number of CBB of 416 and 395, respectively. In the evaluation of trapping design, four types of trapping were tried at the same location. The types of trapping were single funnel red trapping, four funnel red trapping, bottle trap with two straight opposite holes, and bottle trapping with two-zigzag holes. Bottle trapping was made of plastic bottle of 1.5-litre capacity, provided with two holes at its opposite wall. Setting up of the trapping in the field and the observation time were in the same way with the trial in trapping color evaluation. Results obtained indicated that the bottle trapping with two straight opposite holes captured the highest number of CBB followed by four funnel red trapping i.e. 547 and 69 per week, respectively. The peak number of trapped CBB occurred at the third day, as at the color trials. Furthermore, four lures have been evaluated int order to obtain the most effective substances for CBB trapping. Substances of A, B, C and D were set up in a coffee plantation using two types of trapping, four funnel red trapping and bottle trapping with two straight opposite holes. The results showed that the substances of B, C and D captured higher CBB adult than A. Nevertheless, this results was not fully convincing since the number of CBB trapped was low, which was due to low population of the CBB during the last trial

Adaptation Strategies for Personalized Gait Neuroprosthetics

Personalization of gait neuroprosthetics is paramount to ensure their efficacy for users, who experience severe limitations in mobility without an assistive device. Our goal is to develop assistive devices that collaborate with and are tailored to their users, while allowing them to use as much of their existing capabilities as possible. Currently, personalization of devices is challenging, and technological advances are required to achieve this goal. Therefore, this paper presents an overview of challenges and research directions regarding an interface with the peripheral nervous system, an interface with the central nervous system, and the requirements of interface computing architectures. The interface should be modular and adaptable, such that it can provide assistance where it is needed. Novel data processing technology should be developed to allow for real-time processing while accounting for signal variations in the human. Personalized biomechanical models and simulation techniques should be developed to predict assisted walking motions and interactions between the user and the device. Furthermore, the advantages of interfacing with both the brain and the spinal cord or the periphery should be further explored. Technological advances of interface computing architecture should focus on learning on the chip to achieve further personalization. Furthermore, energy consumption should be low to allow for longer use of the neuroprosthesis. In-memory processing combined with resistive random access memory is a promising technology for both. This paper discusses the aforementioned aspects to highlight new directions for future research in gait neuroprosthetics.AK is funded by a faculty endowment by adidas AG.

Chronic Stroke Sensorimotor Impairment Is Related to Smaller Hippocampal Volumes: An ENIGMA Analysis

Background. Persistent sensorimotor impairments after stroke can negatively impact quality of life. The hippocampus is vulnerable to poststroke secondary degeneration and is involved in sensorimotor behavior but has not been widely studied within the context of poststroke upper‐limb sensorimotor impairment. We investigated associations between non‐lesioned hippocampal volume and upper limb sensorimotor impairment in people with chronic stroke, hypothesizing that smaller ipsilesional hippocampal volumes would be associated with greater sensorimotor impairment. Methods and Results. Cross‐sectional T1‐weighted magnetic resonance images of the brain were pooled from 357 participants with chronic stroke from 18 research cohorts of the ENIGMA (Enhancing NeuoImaging Genetics through Meta‐Analysis) Stroke Recovery Working Group. Sensorimotor impairment was estimated from the FMA‐UE (Fugl‐Meyer Assessment of Upper Extremity). Robust mixed‐effects linear models were used to test associations between poststroke sensorimotor impairment and hippocampal volumes (ipsilesional and contralesional separately; Bonferroni‐corrected, P<0.025), controlling for age, sex, lesion volume, and lesioned hemisphere. In exploratory analyses, we tested for a sensorimotor impairment and sex interaction and relationships between lesion volume, sensorimotor damage, and hippocampal volume. Greater sensorimotor impairment was significantly associated with ipsilesional (P=0.005; β=0.16) but not contralesional (P=0.96; β=0.003) hippocampal volume, independent of lesion volume and other covariates (P=0.001; β=0.26). Women showed progressively worsening sensorimotor impairment with smaller ipsilesional (P=0.008; β=−0.26) and contralesional (P=0.006; β=−0.27) hippocampal volumes compared with men. Hippocampal volume was associated with lesion size (P<0.001; β=−0.21) and extent of sensorimotor damage (P=0.003; β=−0.15). Conclusions. The present study identifies novel associations between chronic poststroke sensorimotor impairment and ipsilesional hippocampal volume that are not caused by lesion size and may be stronger in women.S.-L.L. is supported by NIH K01 HD091283; NIH R01 NS115845.

Smaller spared subcortical nuclei are associated with worse post-stroke sensorimotor outcomes in 28 cohorts worldwide

Up to two-thirds of stroke survivors experience persistent sensorimotor impairments. Recovery relies on the integrity of spared brain areas to compensate for damaged tissue. Deep grey matter structures play a critical role in the control and regulation of sensorimotor circuits. The goal of this work is to identify associations between volumes of spared subcortical nuclei and sensorimotor behaviour at different timepoints after stroke. We pooled high-resolution T1-weighted MRI brain scans and behavioural data in 828 individuals with unilateral stroke from 28 cohorts worldwide. Cross-sectional analyses using linear mixed-effects models related post-stroke sensorimotor behaviour to non-lesioned subcortical volumes (Bonferroni-corrected, P < 0.004). We tested subacute (≤90 days) and chronic (≥180 days) stroke subgroups separately, with exploratory analyses in early stroke (≤21 days) and across all time. Sub-analyses in chronic stroke were also performed based on class of sensorimotor deficits (impairment, activity limitations) and side of lesioned hemisphere. Worse sensorimotor behaviour was associated with a smaller ipsilesional thalamic volume in both early (n = 179; d = 0.68) and subacute (n = 274, d = 0.46) stroke. In chronic stroke (n = 404), worse sensorimotor behaviour was associated with smaller ipsilesional putamen (d = 0.52) and nucleus accumbens (d = 0.39) volumes, and a larger ipsilesional lateral ventricle (d = -0.42). Worse chronic sensorimotor impairment specifically (measured by the Fugl-Meyer Assessment; n = 256) was associated with smaller ipsilesional putamen (d = 0.72) and larger lateral ventricle (d = -0.41) volumes, while several measures of activity limitations (n = 116) showed no significant relationships. In the full cohort across all time (n = 828), sensorimotor behaviour was associated with the volumes of the ipsilesional nucleus accumbens (d = 0.23), putamen (d = 0.33), thalamus (d = 0.33) and lateral ventricle (d = -0.23). We demonstrate significant relationships between post-stroke sensorimotor behaviour and reduced volumes of deep grey matter structures that were spared by stroke, which differ by time and class of sensorimotor measure. These findings provide additional insight into how different cortico-thalamo-striatal circuits support post-stroke sensorimotor outcomes
