叶螨是重要的害虫,为害各种经济作物,花卉和树木。近年来,曲于化学农药的广泛使用,使叶螨的天敌大量死亡,因而导致叶螨的为害趣势上升,日益引起农业、林业、城市绿化和园林植保工作者的重视。因为叶螨的体型微小,种类鉴定存在一定困难,我国至今尚有许多地区,还未进行农业螨类调查,山西省关于叶螨种类的报导甚少,为此,我们对山西叶螨种类进行了调

Intermittent fasting(IF)is a type of dietary restriction that involves fasting periods in intervals,which has been used as a strategy to improve health and extend *** fasting is common during the process of biological invasions in ***,it is not clear how invasive animals adjust their resource allocations to survival and reproduction when periodical starvation ***,we used Tetranychus ludeni,a haplodiploid spider mite and an important invasive pest of horticultural crops around the world,to investigate the effects of IF on its life history *** show that IF increased the longevity in females but not in males probably because of differences in resource storage,metabolic rate,and mating cost between *** response to IF,females traded off fecundity and egg size but not the number of daughters for longevity gain,suggesting that *** females can adjust their life history strategies for population survival and growth during invasion *** produced by fasted females realized the same hatch rate and resultant young had the same survival rate as those by unfasted *** addition,IF had transgenerational maternal effects which prolonged offspring development *** suggest that the longer immature developmental period can increase the body size of resulting adults,compensating egg size loss for offspring *** findings provide insight into resource allocations as responses to fasting,knowledge of which can be used for evaluation of pest invasions and for management of animal survival and reproduction by dietary regulations.

Objective:To evaluate the acaricidal activity of extracts of three essential oils of chamomile,marjoram and Eucalyptwi against Tetranychus urtiaie(***.)***:Extracts of three essential oils of chamomile,marjoram and Eucalyptus with different concentrations(0.5%,1.0%,2.0%,3.0%and 4.0%)were used to control *** ***:The results showed that chamomile(Chamomilla recutita)represented the most potent efficient acaricidal agent against Tetranychus followed by marjoram(Marjorana hortensis)and *** LC_(50)values of chamomile,marjoram and Eucalyptus for adults were 0.65,1.84 and 2.18,respectively and for eggs 1.17,6.26 and 7.33,*** of enzymes including glutathione-Stxansferase,esterase(α-esterase andβ-esterase)and alkaline phosphatase in susceptible mites were determined and activities of enzymes involved in the resistance of acaricides were *** enzyme was significantly decreased at LC_(50)of both chamomile and marjoram compared with positive *** chromatography-mass spectrometer(CC-MS)proved that the major compositions of Chamomilla recutita areα-bisabolol oxide A(35.251%),and trans-3-farersene(7.758%),while the main components of Marjorana hortensis are terpincne-4-ol(23.860%),p-cymene(23.404%)and sabinene(10.904%).Conclusions:It can be concluded that extracts of three essential oils of chamomile,marjoram and Eucalyptus possess acaricidal activity against ***.
