Osier weevil started emergence in the last ten days in July and peaked in the tirst and second ten days in August. Emergence on the susceptible species, such as Populus berolinensis, is 5 to 10 days earlier than that on the species of pest-resistance such as P. xiaohei. The adult move slowly, and it spreads or distributes mainly by crawling or by carrying of human beings. Osier weevil has a selection on host species tbr intake nourishment. According to the degree of being addicted, the series can be arranged as Populus berolinensis. Populus staline, Populus pesudo simonii× nigra,Populus xiaohei, Populus pachermis. The adult is likely to dwell on trunks and likely to eat slender and tender branches. Osier weevil makes a choice of host plants to lay eggs. The adult laid more eggs on the P.berolinensis than on P. xiaohei or willow. Most of the eggs laid on the young trees were distributed blow 2 m height. As tree’s age increase, the eggs’ spots get higher and higher. The eggs laid on the eastern and the southern sides of ti1e trunk are more than that laid on the West and the North. P.berolinensis and P. staline are the source trees of osier weevil in artificial Stands in Western Heilongjiang. Cutting the pest source tree, planting pest-resistance species, strengthening the quarantine of the forest plants, and controlling of the diseases and pests timely have very important significance to prevent the occtirrence and damage of this pest.展开更多

Results discovered that the time of emergense of male adults was 24h to 36h earlier than that of female adults. The peak of sex pheromone secretion of the female adults appeared of 24h to 42h after the emergence. The reaction of male adults on the sex pheromone was most sensitive during 30h to 48h after emerged, so the earlier emergence of the male adults was favorable to mating. The phenomenon of repeated mating did not exist in female adults, but the male adults could mate for several times, with maximum of 4 times. There was a definite behavioral reaction during the mating period of male and female adults, and the certain period of feeding and mating times could affect the adults longervity to a certain degree.展开更多

Evidence suggests that infrequent adopting healthy behaviors correlated with many chronic diseases. Healthy behaviors can lead to a marked reduction of morbidity and mortality. Life satisfaction is an important parameter of well-being. Few studies have focused on the association between healthy behaviors and life satisfaction among adults in rural areas. Aim: To establish the determinant and modifiable lifestyle factors associated with life satisfaction among rural adults. Methods: We analyzed our previous health promotion program in a rural area in 2013 obtained from 27 villages (n = 8024) in Yunlin County, Taiwan. The assessment comprised one question assessing self-reported life satisfaction on a 5-point scale (dichotomous: low satisfaction/high satisfaction) and four domain-specific items of health-related behaviors (smoking, oral hygiene, exercise, healthy diet). Logistic regression was used to examine the association between health-related behaviors and life satisfaction adjusted for age, sex, and education. Findings: The mean age was 47.6 years (SD = 16.2), and 56.7% (n = 4551) of the participants were female. Participants with lower life satisfaction reported frequently perceived dissatisfaction with sleep quality (p < 0.001) and health status (p < 0.001). After adjusting for potential confounding variables, the associated risk factors for lower life satisfaction were smoking (OR = 1.20, p = 0.006), less frequently adopted healthy behaviors including dental check (OR = 1.23, p < 0.001), infrequent teeth brushing (OR = 1.12, p = 0.022), infrequent use of dental floss (OR = 1.12, p = 0.028), infrequent consumption of a balanced diet (OR = 1.64, p < 0.001), insufficient vegetable intake (OR = 1.19, p = 0.001), insufficient water intake (OR = 1.14, p = 0.009), and infrequent regular exercise (OR = 1.26, p < 0.001). Conclusions: The findings showed that many adults did not adopt healthy habits in their life. This study identified significant unhealthy behaviors associated with lower life satisfaction, including cigarette smoking, unhealthy diet, poor oral hygiene, and physical inactivity. The enhancement of health promotion programs to improve life satisfaction through decreasing unhealthy habits is necessary for rural adults.展开更多

Here it was investigated the effect of fatty acid or cholesterol rich diets with the possible acceleration of the biological decline in adult hippocampal neurogenesis associated with aging in middle-age rats, and its impact on anxiety and memory function. It was found that a diet of 10 weeks with saturated fatty acids and cholesterol has a detrimental effect on memory function, exerts like-anxiety behavior and diminishes the presence of new generated neurons in the hippocampus in six months old rats.展开更多

Furthermore, previous findings have described a practice in which forensic examiners use the DSM SCID axis II for APD to confirm an ICD 10 diagnosis of DPD. Clinical investigation supported by the use of SCID Axis II for quality assurance was performed on almost half the population of inmates (46.4%) in preventive detention at a high security prison. The inmates had all committed severe violent acts including murder. All the information obtained by applying the DSM IV-TR criteria was tested against the ICD-10 Research Criteria (ICD-10-RC) for Dissocial Personality Disorder (ICD-10, DPD). It was found that all inmates met the ICD-10-RC for (DPD) and the DSM-IV-TR definition for Adult Antisocial Behavior (AAB). On the other hand, none met the DSM-IV-TR criteria for (APD). The SCID Axis II failed to identify inmates with APD because the DSM-IV-TR C-criteria, referring to symptoms of childhood Conduct Disorder (CD), were not met. These findings raise important questions since the choice of diagnostic system may influence whether a person’s clinically described antisocial behaviour should be classified as a personality disorder or not. For the inmates, a diagnosis of APD or DPD may compromise their legal rights and affect decisions on prolongation of the preventive detention. Studies have shown that combining the DSM and the ICD diagnostic systems may have consequences for the reliability of the diagnosis.展开更多

The most abundant species was Psychomyia acutipennis in Trichoptera (95.7%). There was a significant difference between the number of P.acutipennis in the all vegetation area (especially, Salix subfragilis) and the control area (no vegetation) during the investigation periods (P<0.05, Mann-Whitney U-test). Other taxa did not show a significant difference between the all vegetation area and the control. Moreover, the numbers of adult P. acutipennis showed a significant difference in height on each vegetation. In the case of Vicia villosa varia and V. villosa varia plus dead Phragmites australis, the highest number was caught in the traps set in the boundary between one plant and the plant above (P<0.05, Steel-Dwass Test) in May.On the other hand, in the case of almost all vegetation during the investigation periods (except of S.subfragilis in May, Melilotus officinalis plus dead P.australis in June), the highest number was caught in the traps set up within the vegetation (P<0.05, Steel-Dwass Test).As a result, a significant difference was observed in the number of trapped P.acutipennis according to the vegetation and its height.It is suggested that the existence of multiple types of vegetation in the floodplain plays an important role for maintaining the diversity of the fauna there.展开更多
