Curative and Preventive Control of Aceria aloinis (Acari: Eriophyidae) in Southern California.

The aloe mite, Aceria aloinis Keifer, causes physiological and morphological alterations in species of Aloe L. We conducted three trials to evaluate the potential of various miticides for curative and preventive control of damage caused by A. aloinis. In the first trial, the efficacy of nine miticides against aloe mite damage was assessed without the removal of infected tissue in Aloe reitziiae Reynolds. Although significant reductions in the number of mites and eggs were found due to the treatments, miticide application did not reduce the amount of plant area damaged or damage severity. Once the plants are infected, the irreversible damage by aloe mite progresses. The second trial analyzed the effects of seven miticides on aloe mite damage on Aloe 'Goliath' plants in which the damaged tissue was removed. Reduced damage severity and mite number was observed in all treated plants. To determine if aloe mite damage could be prevented, the effects of six miticides with and without surfactant were tested on uninfected plants of Aloe spinosissima A. Berger in a third trial. Except for chlorfenapyr and fenazaquin, all treatments reduced plant damaged area, damage severity, and the number of mites 60 wk following three miticide applications. The severity index in the second and third trials suggested that all treated plants would be marketable. Our study demonstrated that there were miticides that were effective by contact (carbaryl), translaminar (spiromesifen), and systemic (spirotetramat) action, which can be used to cure and to prevent aloe mite plant damage alone or in combination with cultural practices.

Coemployed spouses: differences, strategies, and discrimination.

PIP: The authors explore linkages between family and work roles. They examine patterns of apparent economic strategies of spouses working at a southern university located in a rural area. Their research focuses on spousal economic behavior and specifically addresses the effects of spouses' dual employment on the job status of women, differences between spouses in the timing of education and 1st hire at the university, status consistencies in husband and wife employment levels, and sexual discrimination in job levels and income of coemployed spouses. The study uses data extracted from a personnel data set. Cases from a computerized file were identified in 1980-1981, analyzed with 1981-1982 data, and compared with total work force data for 1982-1983. Slightly more than 1/2, or 123 identified cases, were analyzed. Some study findings follow. 1) Marriage to a coemployed spouse is associated with high occupational levels for female employees. 2) It is the husband's career that generally dictates the entry of a couple into the university's internal labor market. 3) There seems to be a strain toward consistency in the status levels of married pairs. 4) Collaborative strategies are being used to secure economic advances for the family unit. Major efforts regarding education and job selection are directed toward advancing the husband's career preference. However, some exceptions suggest that the pattern is flexible and that economic factors will take precedence over stereotyped sex roles when family needs come into consideration. 5) There is employment discrimination by sex at all levels of the internal labor market being studied. Status and income differentials still exist between males and females. Males in the same occupational statuses are paid more than their female counterparts. Females are concentrated at the lower levels of occupational ranks, males toward the top. Although this study is preliminary, it provides partial support for previous research on coemployed spouses' patterns of educational and occupational attainment, and the persistence of sex discrimination in earnings and occupational prestige.^ieng

The sexual victimization of male children: a review of previous research.

The evidence available at this time indicates that male children are more likely to be abused by nonfamily rather than family members. Residing in a neglectful home or a mother-headed household and having previous homosexual contact tend to heighten risk for sexual abuse by nonfamily members. Familial sexual abuse appears related to residence in a home where other siblings are being abused, where the father was a victim of sexual abuse as a child, and where parents suffer myriad personal and social adjustment difficulties. Effects of male child sexual abuse appear to be serious and long lasting. The scant writings available at this time imply that the sexually abused male child experiences a range of adjustment and self-esteem problems as an adult and may be at heightened risk to become a child sexual abuser.

Adult-child incest: a review of research and treatment.

Although of long-standing theoretical interest in the social sciences, it is only in recent years that researchers and the helping professions have begun to address the reality of incest as a social problem. This paper reviews the literature which addresses adult-child incest as a form of child abuse. Twenty-six independent empirical studies are examined. Related treatment and theoretical literature is also discussed. The following are highlighted: problems of definition; current reporting statistics; obstacles to reporting; incest as a class phenomenon; characteristics of perpetrators, victims, and the other parent; dynamics and circumstances of the incest family; short- and long-term effects of incest on the victim; treating and preventing incest; and legal requirements regarding incest reporting. Finally, attention is directed to methodological problems--small samples, convenience samples, measurement issues, proper evaluation designs for treatment programs, etc.--which very few of the published studies adequately address. Suggestions are made.
