Yanlin Tian. M.S., Purdue University, May 2015. Potential of ozone technology for german cockroach (Blattella germanica (L.)) management. Major Professors: Linda J Mason and Ameya D Gondhalekar. German cockroaches (Blattella germanica (L.)) are important urban pests that adversely impact human health. Previous studies indicated that ozone technology (ozone gas) can be used as a management tool ...

By the year 2025 about 61% of the world’s population will be living in urban areas, especially in developing countries. The urban population will double from 2.4 billion in 1995 to 5 billion in 2025. The world’s urban population is growing 2.5 times faster than the rural population. The impact on health in the urban conglomerations is visible with a significant spread of communicable diseases o...

Anticoagulant rodenticides are widely used in urban areas to control rodent pests and are responsible for secondary poisoning in many nontarget wildlife species. We tested the livers of five coyotes (Canis latrans) in the Denver Metropolitan Area, Colorado, US, for anticoagulant rodenticides. All five livers were positive for brodifacoum, with values ranging from 95 ppb to 320 ppb, and one live...

The ghost ant Tapinoma melanocephalum is a common household pest worldwide. The present study examined the occurrence of the species in urban homes in Korea. During the period of September 2014 to January 2016, T. melanocephalum workers were collected from 58 homes at 29 different localities using bait traps with 10% sugar solution. The species was widely distributed throughout urban homes at 2...

Of the many factors which affect animal production, wildlife is one of the few which has rarely been considered by the Australian Society of Animal Production. A variety of non-domesticated mammals are closely associated with the livestock industries and those which cause production losses are referred to as vertebrate pests in this contract. In some States this definition is carried further by...

The production and use of chemicals is an important source of economic welfare in Ghana. However, many chemicals also enter the environment and chemical pollution remains a major environmental issue in Ghana. In Ghana, mining and agriculture remain the major contributors to chemical pollution. For mining; mercury, cyanide and arsenic are normally the reported cases of contamination. Studies hav...

Trees are essential to urban habitats because they provide services that benefit the environment and improve human health. Unfortunately, urban trees often have more herbivorous insect pests than rural trees but the mechanisms and consequences of these infestations are not well documented. Here, we examine how temperature affects the abundance of a scale insect, Melanaspis tenebricosa (Comstock...

Pesticide use has been the mainstay control of disease vectors and pests of importance to public health [1–3]. However, three recent developments have raised concern over how pesticides used for public health (which include vector-control pesticides, household insecticides, and professional pest-management pesticides [4]), are being regulated, managed, and monitored in affected countries. Distu...

Climate warming is predicted to cause many changes in ectotherm communities, one of which is phenological mismatch, wherein one species' development advances relative to an associated species or community. Phenological mismatches already lead to loss of pollination services, and we predict that they also cause loss of biological control. Here, we provide evidence that a pest develops earlier du...
