The behavior of Japanese cedar (Cryptomeria japonica) and Japanese cypress (Chamaecyparis obtusa) pollens in an urban area was examined through the measurements of the dispersion characteristics at the various sampling locations in both outdoor and indoor environments. Airborne pollens were counted continuously for three months during the Japanese cedar pollen and Japanese cypress seasons in 20...

the mealybug fauna of southern iran (systan & baluchestan, hormozgan, bushehr, khuzeztan and fars provinces) is unknown to many coccidologists. in this paper, 17 mealybug species from the south of iran with their host plants are reported.maconellicoccus hirsutus (green), nipaecoccus viridis (newstead) and planococcus ficus (signoret) are the important pests and ferrisia virgata (cockerell), dys...

Cypress canker caused by Seiridium cardinale was controlled by benomyl and chlorothalonil but not by tribasic copper sulfate. Cypress canker has been present in California since 1927 where it has caused considerable damage to planted Monterey cypress, Cupressus macrocarpa (6). The popularity of this California native range and usually canker disease appears, but some uninformed people still pla...

Leyland's cypress (xCupressocyparis leylandii) is a putative, spontaneous hybrid between Chamaecyparis nootkatensis and Cupressus macrocarpa. To investigate this putative origin, twenty five Leyland's cypresses were sampled, along with living, putative parents of Ch. nootkatensis and Cup. macrocarpa from gardens in the UK. The DNA was extracted and analyzed by DNA fingerprinting (RAPDs) and Int...

The Seminole Indians of Florida were studied on thek three reservations for blood types, red cell enzymes, serum proteins, physical measurements, and relationships. Both serologic and morphologic factors suggest their close similarity to other Indians and small amount of admixture. The Florida Seminoles are similar to Cherokee “full-bloods” in their absence of Rho and their incidence of 0 and M...

BACKGROUND : Cypress pollen is becoming an increasing cause of respiratory allergy in some regions worldwide. OBJECTIVE : The aim of this study was to determine some of the main allergens implicated in the common cypress (C. sempervirens) pollen allergy. METHODS : Pollen extracts were optimized by using some detergents and chaotropes in order to solubilize both water and non-water soluble p...

Stem diameter at breast height (DBH) and tree height (H) are commonly used measures of tree growth. We examined patterns of height growth and diameter growth along a stem using a 20-year record of an even-aged hinoki cypress (Chamaecyparis obtusa (Siebold & Zucc.) Endl.) stand. In the region of the stem below the crown (except for the butt swell), diameter growth rates (ΔD) at different heights...

Biological control or the use of natural enemies is an alternative pest management strategy for dealing with arthropods. However, natural enemies may not always provide adequate control of plant-feeding insects and mites in greenhouses. As a result, research has assessed the concept of using natural enemies in conjunction with pesticides and the potential compatibility when both pest management...

In this study, the effects of different flight altitudes on tree height estimates with a small-footprint scanning lidar were investigated and assessed in mountainous forests with poor laser penetration rates. The study area was closed-canopy evergreen coniferous plantations dominated by Japanese cedar (Cryptomeria japonica) and hinoki cypress (Chamaecyparis obtusa) in Japan. The stand age range...

The invasive polyphagous cotton mealybug, Phenacoccus solenopsis Tinsley has emerged as a serious sucking pest of cotton. laboratory and field bioassays seven selected insecticides belonging to five toxicant groups were evaluated against P. their most abundant natural predators, Chrysoperla carnea (Steph.) Hyperaspis vinciguerrae Capra. Based on the toxicity index toxic group under conditions w...
