An annotated list of 83 scale insect species (Hemiptera: Sterorrhyncha: Coccoidea) recorded from Saint Lucia is presented, based on data gathered from UK quarantine interceptions, samples collected in an urban coastal habitat in the North West of the Island in 2013, and published records. Thirty-three species (40%) are recorded for the first time for the country, including Dysmicoccus joannesia...

In the laboratory, Argentine ant, Linepithema humile (Mayr), mortality was positively correlated to the length of an aromatic cedar mulch section that had to be crossed before food could be reached. When ants could access food without crossing the mulch, mortality was not correlated to mulch section length. In the field, Argentine ants showed a tendency to avoid aromatic cedar mulch as a nestin...

Cereal Chem. 85(3):276–282 Rice quality can vary inexplicably from one lot to another and from year to year. One cause could be the variable temperatures experienced during the nighttime hours of rice kernel development. During the fall of 2004, a controlled temperature study was conducted using large growth chambers, testing nighttime temperatures of 18, 22, 26, and 30°C from 12 a.m. until 5 a...

(2012), http://dx.doi.org/1 Swamps, peatlands, and other wetland ecosystems can store vast amounts of carbon in organicallyderived peat soils. Wildfires during severe droughts can produce smoldering combustion in these soils, releasing large quantities of carbon to the atmosphere and causing dramatic changes at the local ...

Foreign exploration for natural enemies of pink hibiscus mealybug, Maconellicoccus hirsutus , was conducted in Australia from 2000 to 2002. In Queensland, the predaceous beetle Cryptolaemus montrouzieri , the predaceous drosophilid fly, Cacoxenus perspicax and the encrytid parasitoid Gyranusoidea indica were recovered. In Western Australia and the Northern Territory a predatory noctuid , Mataeo...

Weed control is an important aspect during the first few years of Christmas tree establishment, as weed competition directly relates to rate growth this time. The objectives study were evaluate efficacy organic mulch and herbicide combinations determine their phytotoxic effects on four different species trees establishment stage: Fraser fir (Abies fraseri (Pursh) Poir), blue spruce (Picea punge...

of field-grown hinoki cypress (Chamaecyparis obtusa (Sieb. et Zucc.) Endl.) was nondestructively measured at monthly intervals over 1 year with an enclosed standing tree method. The relationship between monthly specific respiration rate and monthly mean relative growth rate at the individual tree level was described by a linear equation. During the dormant season, respiration was used mainly fo...

Introduction: Lichen diversity, community structure, composition and species abundance have been used as indicators of the integrity ecological continuity tropical forest ecosystems. Objectives: To assess corticolous lichen composition, importance three forested stands differing in time abandonment how passive restoration influences assemblage. Methods: We surveyed individual lichens on tree st...
