An outbreak of the sweetpotato whitefly, Bemisia tabaci （Gennadius）, biotype B occurred in the Imperial Valley, California in 1991. The insects destroyed melon crops and seriously damaged other vegetables, ornamentals and row crops. As a result of the need for sampling technology, we developed a whitefly trap （named the CC trap） that could be left in the field for extended time periods. We used the traps to monitor populations ofB. tabaci adults during year-round samplings from 1996 to 2002 to study variations in the weekly trap catches of the insect. The greatest number ofB. tabaci adults was recorded in 1996, followed by a continuing annual decrease in trap catches each year through 2002. The overall decline of B. tabaci is attributed in part to the adoption of an integrated pest management （IPM） program initiated in 1992 and reduced melon hectares from 1996 to 2002. Other factors may also have contributed to the population reductions. Seasonally, B. tabaci trap catches decreased during the late summer and fall concurrent with decreasing minimum tempera- tares that are suggested to be a significant factor affecting seasonal activity and reproduction.

The effects of adrenalectomy and corticosterone supplementation on the neurotoxicity of trimethyltin (TMT) were tested. CD-1 mice with or without adrenalectomy were injected with TMT at a dose of 3.0mg/kg body wt. At 48h post-TMT administration, the animals were killed for pathological examination. It was found that the adrenalectomized animals developed even more severe lesions in the hippocampal formation (fascia dentata granule cells) than the intact animals. When animals were given a supplement of corticosterone pellets at doses of 0.15, 1.5, and 7.5mg, there was a reduction of lesion development. Total alleviation of pathology was seen at the two higher doses of supplementation. Our present investigation strongly indicates that there may be a close and important interrelationship between TMT-induced neurotoxicity and adrenal function. 1989 Academic Press, Inc.

Aphanomyces root rot(ARR) of field pea(Pisum sativum), caused by Aphanomyces euteiches, can cause severe root damage, wilting, and large yield losses under wet soil conditions. To identify ways to manage this disease, the effect of A. euteiches inoculum density on field pea was studied under greenhouse and field conditions in 2015 and 2016. Increases in inoculum density reduced seedling emergence, root nodulation, and plant vigor, and resulted in increased root rot severity in both field and greenhouse tests. Seed treatments with the fungicides Apron Advance(thiabendazole + fludioxonil + metalaxyl) + Vibrance(difenoconazole + metalaxylM + sedaxane), INTEGO Solo(ethaboxam), BAS 516F(boscalid + pyraclostrobin), BAS 720F(metalaxyl + pyraclostrobin + fluxapyroxad), and BAS 516F + BAS 720F(3:1) were evaluated for their efficacy against ARR. All seed treatments except Apron Advance + Vibrance reduced root rot severity under controlled conditions. BAS 516F, BAS 720F and INTEGO Solo improved plant vigor and all treatments reduced seedling blight to varying degrees under greenhouse conditions, but not in the field. A collection of 22 pea genotypes was evaluated for resistance to root rot in field plot experiments. Line 00–2067 showed the least severe root rot symptoms,whereas ‘Spring D' showed the lowest reduction in yield. The results suggest that there may be an opportunity to combine partial host resistance and fungicidal seed treatments to adequately manage ARR of field pea.

Chemical ecology of the spruce bark beetle lps typographus （L.） was reviewed. The outbreak of *** in central Europe triggered extensive research on chemical ecology, Males initiate host location and produce semiochemicals which attract both males and females, A successful mass attack must first overcome the resistance of the host tree. Pioneer I. typographus evolved to use the resin flow of host trees as kairomones in host location, and synthesized semiochemicals initially to detoxify the resin. If small bark beetle populations infest healthy trees, mass attack is prevented by host resistance, Nine monoterpene alcohols were found in male hind-guts, including cis-verbenol （cV） and 2-methyl-3-buten-2-ol （MB） which are regarded as primary aggregation pheromones, and a low proportion of lpsdienol （ld） which increases attractiveness of cV and MB, Verbenone （Vn） and Ipsenol （le） are anti-aggregation pheromones, that play important roles in adjusting attack density and insect density under the bark. Non-host volatiles are repellent to L typographus, so that beetles do not waste energy boring into non-host trees. The relationship between host resistance, pheromone compounds and behavior, non-host volatiles, bioassays and mass trapping are reviewed, Results of field bioassays stressed that traps baited with specific pheromones could be used as a reasonable protection measure.

"Evolutionary psychology is an approach to psychology, in which knowledge and principles from evolutionary biology are put to use in research on the structure of the human mind" (Cosmides & Tooby, 2001, p。1)。The approach can be used to study and to provide broad theoretical framing of nearly all of the issues and topics within the traditionally defined fields of psychology。The 19 papers included in this special issue on evolutionary psychology are written by leading scholars in the field and address topics that can be organized by the familiar divisions of cognitive, developmental, and social psychology。
