Growth chamber and field studies were conducted to investigate the possibility of an interaction between the herbicides 4-(methylsulfonyl)-2,6-dinitro-N,N-dipropylaniline (nitralin), a,a,a-trifluoro-2,6-dinitro-N,N-dipropyl-p-toluidine (trifluralin), 3- (m-tri-fluromethylphenyl)-1,1-dimethylurea (fluometuron), and 2,4-bis(isopropylamino)-6-methylmercapto-s-triazine (prometryne), and the seedling disease organism Rhizoctonia solani Kuehn in cotton (Gossypium hirsutum L.). When high levels of trifluralin or prometryne were used in the growth chamber, an interaction with the pathogen that was injurious to the cotton occurred. Prometryne and fluometuron produced an antagonistic effect on R. solani.Under field conditions, R. solani usually caused cotton injury. Interactions injurious to the cotton occurred between trifluralin and a low level of R. solani and between nitralin and a high level R. solani infestation. No interactions occurred with fluometuron or prometryne. In all instances, the effect occurred only when the herbicides were being used at high rates.

Spruce Beetle

AbstractField studies were carried out on effect of attack by unmated spruce beetles, Dendroctonus obesus (Mann.) on log attractiveness. Test logs were screen-covered or sprayed with insecticide. Trays beneath logs, with glass-barrier traps beside them, were used to measure response of beetles from natural populations.About 89% of the beetles attracted at six replicate sites were taken at logs containing introduced females. Males always predominated in responses to these logs. After the initial flight, about equal numbers of each sex responded to logs without introduced females. Response to the latter dropped to a low level after the initial flight, but beetles continued to respond well to logs attacked by females throughout the flight period. Use of increased attractiveness to logs following introduction of female beetles shows promise as a means of studying, directing, or controlling infestations of the spruce beetle.

Descriptive Qualitative

The purpose of this study is to determine the extent of the condition of household financial literacy in community-based tourism which has continued to develop. Another thing that is also being studied knows the right way that households in the community-based tourism area are more empowered by increasing their financial literacy. In this research, the approach used is descriptive qualitative by conducting field studies to explore information from questionnaires given to respondents who are households in the community-based tourism area. Then conclude through purposive question to be able descripting real conclusions. The findings of this study indicate that not many households in community-based tourism are well literate with a low level of financial knowledge, so they are still unable to optimize the income they receive. There is a scheme from the government to help improve the welfare of the community in community-based tourism areas with financial assistance and financial knowledge. This research only conducts studies in certain areas in the area around Junrejo municipality, Batu, East Java. The location is an area that has community groups that mostly have livelihoods as provider of tourism good and services.

We investigated the change of tryptophan-niacin metabolism in rats with puromycin aminonucleoside PAN-induced nephrosis, the mechanisms responsible for their change of urinary excretion of nicotinamide and its metabolites, and the role of the kidney in tryptophan-niacin conversion. PAN-treated rats were intraperitoneally injected once with a 1.0% (w/v) solution of PAN at a dose of 100 mg/kg body weight. The collection of 24-hour urine was conducted 8 days after PAN injection. Daily urinary excretion of nicotinamide and its metabolites, liver and blood NAD, and key enzyme activities of tryptophan-niacin metabolism were determined. In PAN-treated rats, the sum of urinary excretion of nicotinamide and its metabolites was significantly lower compared with controls. The kidneyα-amino-β-carboxymuconate-ε-semialdehyde decarboxylase (ACMSD) activity in the PAN-treated group was significantly decreased by 50%, compared with the control group. Although kidney ACMSD activity was reduced, the conversion of tryptophan to niacin tended to be lower in the PAN-treated rats. A decrease in urinary excretion of niacin and the conversion of tryptophan to niacin in nephrotic rats may contribute to a low level of blood tryptophan. The role of kidney ACMSD activity may be minimal concerning tryptophan-niacin conversion under this experimental condition.
