First Record Of Planchonia Stentae (Brain, 1920) (Hemiptera: Coccomorpha: Asterolecaniidae) On Asclepias Curassavica Linnaeus, 1753 (Gentianales: Asclepiadaceae) In Mexico, With Observations On Parasitic Encyrtidae, Hipolito Cortez-Madrigal, Arturo Ramírez-Cruz, Christof F. Stumpf

In April 2018, specimens of an asterolecaniid were collected on infested wild plants of Asclepias curassavica Linnaeus, 1753 (Gentianales: Asclepiadaceae) in Jiquilpan, Michoacan, Mexico. The collected specimens were identified as Planchonia stentae (Brain, 1920) (Hemiptera: Asterolecaniidae). In this paper, we record for the first time the presence of P. stentae infesting A. curassavica in Mexico.

Stink bugs (Hemiptera: Pentatomidae) are agricultural pests of increasing significance in the North Central Region of the United States, posing a threat to major crops such as soybean. Biological control can reduce the need for insecticides to manage these pests, but the parasitism of stink bugs byTachinidae (Diptera) is poorly characterized in this region. The objective of this study was to evaluate the rate of parasitism of stink bugs by tachinids over 2 yr from nine states across the North Central Region. Parasitism was assessed by quantifying tachinid eggs on the integument of stink bug adults. Parasitism rates (i.e., percent …

Parasitoids are important natural enemies of house flies and other muscoid flies. The two most commonly used methods for collecting fly parasitoids from the field have distinct advantages and disadvantages. Collections of wild puparia depend on the ability to find puparia in sufficient numbers and are prone to localized distortions in relative species abundance because of the overrepresentation of samples from hot spots of fly larval activity. Placement and retrieval of sentinel puparia is convenient and allows consistent sampling over time but is strongly biased in favor of Muscidifurax spp. over Spalangia spp. An improved sentinel method is described that …
Diet Of Spalangia Cameroni (Hymenoptera: Pteromalidae), A Parasitoid Of Filth Flies, Elizabeth Taylor
Diet Of Spalangia Cameroni (Hymenoptera: Pteromalidae), A Parasitoid Of Filth Flies, Elizabeth Taylor
Graduate Research Theses & Dissertations
Parasitoid wasps are often part of the rich invertebrate communities in decaying organic matter where their hosts are found. However, little is known about what adults of these parasitoids eat. Most parasitoid wasps parasitize herbaceous insects, so nectar from flowers often is readily available. The present study examined feeding by adult Spalangia cameroni Perkins (Hymenoptera: Pteromalidae), a species that burrows through manure, where it finds and parasitizes pupae of filth flies. Feeding on host fluids occurs in many parasitoid wasps, including S. cameroni. In the laboratory, these wasps also readily feed on honey or a sucrose solution, which increases their …
Management Of Sugarcane Aphid (Melanaphis Sacchari) Using Biological And Cultural Tactics In Kentucky, Nathan Harriman Mercer
Management Of Sugarcane Aphid (Melanaphis Sacchari) Using Biological And Cultural Tactics In Kentucky, Nathan Harriman Mercer
Theses and Dissertations--Entomology
In 2013, a new aphid pest of sorghum, the sugarcane aphid Melanaphis sacchari Zehntner (Hemiptera: Aphididae), was found in the southern US, and caused significant yield loss in sorghum. Since then, M. sacchari has spread to most of the sorghum growing regions. Unmanaged populations can cause complete crop loss in grain, forage and sweet sorghum. M. sacchari cannot survive winters without a live plant tissue and must recolonize much of its pest range annually. Sweet sorghum (Sorghum bicolor) is an important crop for many growers in Kentucky, producing $16-25 million a year from its syrup. Biological control of …
