Arthropod Arbiters: Natural Enemy Communities Mediate The Effects Of Landscape And Local-Scale Complexity On Lygus-Induced Crop Loss In Organic Strawberries, Adrian Lu, David J. Gonthier, Amber Sciligo, Karina Garcia, Taiki Chiba, Gila Juárez, Claire Kremen

Entomology Faculty Publications

Sustainable pest management requires growers and regional land managers to consider the relationships among pest management practices, pest and natural enemy communities, crop loss, and multi-scalar habitat complexity. However, the causal links among these variables, in particular potential interactions between landscape and local-scale habitat complexity, remain underexplored. In the context of organically managed strawberry crops in California’s Central Coast, we tested the independent effects of landscape and local habitat complexity gradients on arthropod communities and crop loss using a piecewise structural equation model (PSEM). We found that landscape-scale woody habitat proportion indirectly decreased crop loss through its positive effect on …

Insect Pests And Their Management In Oats, Department Of Primary Industries And Regional Development, Western Australia

Grains and other field crops factsheets

Field pests

Damage from invertebrate pests is generally not a major factor for oat crops, however there is a zero tolerance to live pests in export hay.

Significant damage can occur if pest populations build up. Planning rotations to minimise pest carryover, timely sowing, adequate crop nutrition, and good control of weed and root diseases will assist in reducing the likelihood of crop damage by insect pests. Check crops regularly throughout their growth for field insects.

• Control redlegged earth mite and lucerne flea during the seedling stage if necessary.

• Aphids should be checked for and controlled from flag …

Invasive Forest Pest Education Through Identification, Reporting, And Children’S Introduction Brochures, Lauren E. Keefe

Department of Entomology: Distance Master of Science Projects

Forest pest insects, whether native or non-native, can be extremely detrimental to the health of a landscape, and can contribute to massive ecological, economic, and cultural losses. Unless directly exposed to the damage these pests cause, many people do not seek to become informed on the insects. A series of brochures was thus created as a collaboration between the online UNL M.S. in Entomology requirements and a need for updated Nebraska Forest Service Forest Health brochures. These brochures focus on invasive forest insect identification and reporting, as well as introducing the concepts of the invasives to children.

Dispersal of chalcid wasp larvae inhabiting the seeds of angiosperms by wild birds in North America has never been verified. I describe adult Megastigmus aculeatus Swederus that successfully emerged from seeds extracted from the droppings of six species of native North American non-captive birds. Rosa setigera is also confirmed as a host for this wasp for the first time.

Laboratory Rearing Methods For The Soybean Tentiform Leafminer (Lepidoptera: Gracillariidae), A New Pest Of Soybean, James Menger, Arthur Ribeiro, Fabio Fuhr, Robert L. Koch

The Great Lakes Entomologist

Soybean tentiform leafminer (STL), Macrosaccus morrisella (Fitch) (Lepidoptera: Gracillariidae), is a leaf-mining microlepidopteran native to North America that was recently discovered feeding on soybean, Glycine max (L.) Merr., in Canada and the United States. A laboratory rearing system for STL was developed on live soybean plants. The methods for continuous rearing or cyclic (i.e., generational) production of insects are described herein. All rearing was performed in a walk-in environmental chamber at 25°C (±2°C), with ~70% relative humidity and a photoperiod of 16:8 (L:D). Adults of STL were allowed to oviposit on clean soybean plants in an oviposition cage. Soybean plants …

The Great Lakes Entomologist

We present results of the first long-term study on spatiotemporal variations in the composition and structure of ground-dwelling beetle assemblages from a grassland and adjacent woods in eastern Canada. It is the third part of an investigation on the beetle biodiversity using diverse methods between 2006 and 2012. During the entire snow-free season (April/May to October) in 2006–2010, we collected by pitfall trapping 67694 individuals representing 386 Coleoptera species and morphospecies belonging to 35 families in southern Québec. Adventive species represented at least 51.9% of individuals. Carabidae and Staphylinidae were the most abundant families and had the highest species richness …

Ambrosia Beetle (Coleoptera: Curculionidae: Scolytinae) Responses To Ice Storm Damage In Mesic, Mixed Deciduous Forests In Southeast Ohio, United States, Christopher J. Hayes, Richard M. Turcotte

The Great Lakes Entomologist

In the eastern United States abiotic forest disturbances are common and cause extensive tree damage. Freshly broken trees and tree branches attract bark and ambrosia beetles that utilize inner bark and xylem of damaged branches and trees to fill requisite habitat needs. An ice storm in February 2003 on the Wayne National Forest presented an opportunity to study the local ambrosia beetle species and their reaction to this storm event. Ethanol baited Lindgren traps were deployed from 2003-2006 starting in the summer after the storm. Eight native and introduced Scolytinae ambrosia beetle species were trapped in large numbers (>500 …

Impact Of Debarking And Bark Grinding On Survival Of Ips Calligraphus (Coleoptera: Curculionidae: Scolytinae), Robert A. Haack, Toby Petrice, John Foltz, Hui Ye

The Great Lakes Entomologist

Chipping and debarking of infested woody material such as branches and logs are common sanitation methods used to kill bark- and wood-infesting insects. The sixspined ips, Ips calligraphus (Germar), is a native North American bark beetle (Coleoptera: Curculionidae: Scolytinae) that infests several pine (Pinus) species. We evaluated I. calligraphus mortality after debarking and grinding, using 12 recently cut longleaf pine (Pinus palustris Mill.) logs that had undergone natural colonization for three weeks in Florida. Initial bark beetle densities were estimated from samples collected the day before debarking. Similar amounts of bark were collected at three steps in …

Phenology And Host Choice Among Common Yet Little Understood Wood Borers (Coleoptera: Bostrichidae) In A Midwestern Savanna, Noah I. Finney, Derek W. Rosenberger

The Great Lakes Entomologist

Horned powder-post beetles (Coleoptera: Bostrichidae) are a geographically widespread family of wood-boring beetles. While members of this family represent important grain pests, are often intercepted in ports, and may play an important role in ecosystem processes, little work has investigated bostrichid life history in their native ranges. This gap limits our ability to assess ecosystem services and invasiveness. Three native species, Amphicerus bicaudatus (Say), Scobicia bidentata (Horn), and Xylobiops basilaris (Say), are commonly found in savannas in Northern Illinois. Although little is currently known about the life history of S. bidentata, A. bicaudatus and X. basilaris can be minor pests …

Changes In Ground Beetle (Coleoptera: Carabidae) Species Assemblages After Removal Of Red Pine (Pinus Resinosa) Overstory On Dry Sand Prairie Sites In Michigan, Robert A. Haack, Toby Petrice, Robert L. Davidson, Robert E. Acciavatti

The Great Lakes Entomologist

Ground beetle (Coleoptera: Carabidae) species assemblages were studied at sites on the Huron-Manistee National Forests in Newaygo County, Michigan. The goal was to monitor changes in carabid diversity on areas where mature red pine (Pinus resinosa Sol. ex Aiton) was removed during the 1996-1997 winter and compare with carabid diversity at nearby natural dry sand prairie sites, natural oak-pine barrens, and uncut red pine stands. The red pine had been planted on dry sand prairie sites during 1940-1950. Sampling with pitfall traps occurred during May-August in both 1996 and 1997, but only July-August in 1999. Overall, 16,259 carabid specimens …

Impacts Of Cruciferous Extracts On The Parasitism Efficiency Of Diadegma Insulare; A Hymenopterous Parasitoid Of The Diamondback Moth, Muhammad Sajid Qureshi, Wali Muhammad, Muhammad Adnan Bodlah, Abdul Mannan Hamzah, Muhammad Saeed, Riaz Hussain

Journal of Bioresource Management

Herbivore's attack stimulates chemical production in the plants; that communicates with natural enemies (chemical communication) and urges them for help (i.e. cry-for-help phenomenon). Such chemicals play an important role to attract the parasitoids and increase the chances of host pests' encounter. Current studies were performed to observe the extracts' efficacy in order to attract the parasitoid (i.e. Diadegma insulare) and thereby increase the likelihood of encounter with the host pest (i.e. Plutella xylostella). Cruciferous cultivars' extracts were developed and applied with artificial release of parasitoids under semi-field conditions. Findings revealed that extracts had the potential to enhance the …
