For the colonial cliff swallow, Petrochelidon pyrrhonota, which occupies colonies of widely different sizes, we used a 30-year field study in western Nebraska to investigate how the extent of infestation by ectoparasites and colony size affected breeders' colony site fidelity between years.
The details of location of pest incidence and extent of infestation were later transferred to the field map in order to understand the spatial pattern of infestation (Fig 5).
The questionnaire included items on time course, manifestations, and extent of the infestation; control measures undertaken; and effects of the infestation on shelter residents and staff.
The dive Friday morning was one of a series this week to gauge the extent of the infestation of the non-native fish on the region's reefs, using a vessel donated by OceanGate Inc., which operates submersibles for oil and gas exploration, scientific research, marine engineering and other uses.
Economically, with double treatment regime of Ecotix® a pour-on preparation, the farmer can save up to 2.5 USD per animal per each six months of dry season when the extent of tick infestation is relatively high.
This project is leading to high-tech efforts to monitor the extent of these infestations, predict their spread, and thereby develop new containment and control strategies.
There are few studies that report the extent of rodent infestations still occurring on ships.
This study aimed at determining the extent of tick infestations in extensively grazed cattle and assess the efficacy of Ecotix® acaricide (2.5% high cis cypermethrin) in Mvomero district in Tanzania.
Several factors have been identified that are useful for understanding trap adoption and acceptability in poor communities, such as whether the traps are seen to be effective, whether they are easy to use, whether there is an additional benefit to using them and the extent of the rodent infestation [ 32- 36].
In conclusion, our study documents the broad extent of bed bug infestations in an urban environment.
Data from public health officials and pest control operators provided markedly different perspectives on the extent and localization of infestations.
