Resource amount and discontinuity influence flight and reproduction in Hippodamia convergens (Coleoptera: Coccinellidae)
<p>Industrial-scale agriculture creates a mosaic of large monocultures in the landscape, where seasonal cropping cycles generate discontinuous resource availability for insect predators both spatially and temporally. In this environment, selection will favor predator movement and reproductive behaviors that optimize the location and effective utilization of resource (prey) pulses that are both patchy and ephemeral in nature. Using a model system to study predator movement and reproduction, we tested how discontinuous periods of food resource access that mimic fluctuating resource populations (aphids) would influence flight behavior and reproduction of a highly mobile predator, Hippodamia convergens (convergent lady beetle), and possibly modify energetic trade-offs between these behaviors. Examining how these factors affect reproduction and movement in a lab context is an important first step toward understanding their corresponding performance in the field. Adult beetles were provided either short (3h) or long (6h) food pulses daily (continuous availability) or short (6h) or long (12h) food pulses every other day (discontinuous availability). We measured pre-oviposition period, fecundity, and fertility during an 18-day oviposition period, and female tethered flight activity (3h) before and after the oviposition period. We found that discontinuous food access delayed the onset of oviposition in the high food quantity treatment; fewer females laid eggs overall, and 18-d fecundity was lower compared to continuous provision of the same food quantity. A longer pre-oviposition period was associated with fewer reproductive days and lower fitness. Flight distance and fecundity were negatively correlated, suggesting that energetic expenditure in flight can deplete energetic reserves otherwise used for subsequent reproduction. The negative fitness effects of discontinuous resource access at fine temporal scales reveal how similar gaps in resource availability could influence lady beetle population dynamics and their ecosystem services within the agricultural landscape. Understanding how resource availability patterns affect lady beetle fitness and behavior can inform agricultural land management strategies to enhance their biological control services.</p>

Kellogg Biological Station site, station Treatment 1, standard levels of chemical inputs, conventional chisel plowed tillage, study of animal abundance of Hippodamia convergens in units of numberAdultsPerYellowStickyTrap on a yearly timescale
The EcoTrends project was established in 2004 by Dr. Debra Peters (Jornada Basin LTER, USDA-ARS Jornada Experimental Range) and Dr. Ariel Lugo (Luquillo LTER, USDA-FS Luquillo Experimental Forest) to support the collection and analysis of long-term ecological datasets. The project is a large synthesis effort focused on improving the accessibility and use of long-term data. At present, there are ~50 state and federally funded research sites that are participating and contributing to the EcoTrends project, including all 26 Long-Term Ecological Research (LTER) sites and sites funded by the USDA Agriculture Research Service (ARS), USDA Forest Service, US Department of Energy, US Geological Survey (USGS) and numerous universities. Data from the EcoTrends project are available through an exploratory web portal (http://www.ecotrends.info). This web portal enables the continuation of data compilation and accessibility by users through an interactive web application. Ongoing data compilation is updated through both manual and automatic processing as part of the LTER Provenance Aware Synthesis Tracking Architecture (PASTA). The web portal is a collaboration between the Jornada LTER and the LTER Network Office. The following dataset from Kellogg Biological Station (KBS) contains animal abundance of Hippodamia convergens measurements in numberAdultsPerYellowStickyTrap units and were aggregated to a yearly timescale.
