Experiments on a mealybug infesting apple and a mealybug infesting catalpa
1. The developing time of the mealybug from catalpa exceeded that of the mealybug from apple. 2. In no experiment did cross-breeding of the mealybug from apple and from catalpa take place. 3. Each mealybug was able to live successfully on both hosts. 4. The parasites, Clausenua purpurea Ishii, from …

Biodiversity and systematics of parasitic Crustacea infesting southern African freshwater fishes
Crustaceans (Arthropoda: Crustacea) are regarded as the most morphologically diverse group in the phylum Arthropoda, and they have the greatest diversity of parasitic forms. Parasitic crustaceans have adapted several morphological and physiological characteristics that enable them to thrive in an …

Surveying house-infesting ants after 87 years: species identity and economic impact in central Illinois
… R. Smith conducted a 3-year survey of house-infesting ants in Urbana, Illinois. He reported species diversity, relative abundance, and the economic impact of control measures. I replicated this study in 2012-2013 to examine how the house-infesting ant fauna and measures used for their control …

Molecular Detection of Tick-Borne Pathogens Associated With Ixodid Tick Species Infesting Migratory Songbirds and Ruminants
… of tick-borne pathogens was examined in ticks infesting migratory songbirds and Pakistani ruminants. During spring migration seasons, ticks were removed from northward-migrating songbirds in Louisiana and identified as Amblyomma Jongirostre, Amblyomma nodosum, Amb/yomma ca/caratum, Amblyomma …

Chionodes mediofuscella (Clemens) (Lepidoptera:Gelechiidae), an indigenous insect infesting the seeds of giant ragweed (Ambrosia trifida L.) (Compositae)
… Chionodes mediofuscella (Clemens), a seed-infesting gelechiid, may provide this control in areas where giant ragweed has escaped its natural enemies. The biology and immature stages of this species are poorly known. The egg, last instar, and pupal stadium are described. Egg: .4-.5 mm in …

Bionomics and Sampling of the Imported Crucifer Weevil, Baris Lepidii Germar
… In May of 1977 this insect was discovered infesting commercial horseradish fields in Illinois. A research program composed of several subsections was designed to obtain useful information on the bionomics of the imported crucifer weevil. The intent of the research was to obtain data which …

Effects of intertidal height and infestation by Fabia Subquadrata Dana on glycogen, lipid and body component indices of Mytilus Californianus Conrad
… of bivalve parasites have been devoted to groups infesting commercially important mollusks, notably trematodes and copepods. Another group of bivalve symbionts which has been known since the early nineteenth century is the brachyuran genus Pinnotheres Latreille, 1802 (commonly known as pea crabs). …

Inline disinfestation of canola seeds from red flour beetles using a 50-ohm RF technology
… thermal mortalities of adult red flour beetles infesting canola seeds at 9% moisture content (MC) were determined treated using a 50-ohm radio frequency (RF) heating system. The infested seeds were treated between 297 K and 338 K at RF heating power of 3 kW, 5 kW, and 7 kW. The survival rate of …

Investigations into the nature of the potato psyllid toxin
… were studied under greenhouse conditions by infesting the plants with potato psyllids. Dramatic yield losses occurred in four cultivars of potato studied. Varietal responses showed that early maturing cultivars had less damage, as measured by loss of tuber yield, than later cultivars. Another …
