Insect olfactory systems provide unique opportunities for recording odorant-induced responses in the forms of electroantennograms (EAG) and single sensillum recordings (SSR), which are summed responses from all odorant receptor neurons (ORNs) located on the antenna and from those housed in individual sensilla, respectively.

Herbivore-induced Blueberry Volatiles and Intra-plant Signaling

A push-pull method for collecting plant volatiles is described. The method allows for a comparison of volatiles induced by herbivore feeding, exogenous methyl jasmonate, and mechanical damage. This technique is also used to investigate the volatile response of undamaged branches to exposure to volatiles from herbivore-damaged branches within blueberry plants.

The capability to localize an odor source is necessary for insect survival and is expected to be applicable to artificial odor-tracking. The insect-controlled robot is driven by an actual silkmoth and enables us to evaluate the odor-tracking capability of insects through a robotic platform.

Here, we present a protocol to investigate the host-tissue distribution, transmission mode, and effect on the host fitness of a densovirus within a lepidopteran species, the cotton bollworm. This protocol can also be used for studying the interaction between other orally-transmitted viruses and their insect hosts.

We present three new methods to study gustatory coding. Using a simple animal, the moth Manduca sexta (Manduca), we describe a dissection protocol, the use of extracellular tetrodes to record the activity of multiple gustatory receptor neurons, and a system for delivering and monitoring precisely timed pulses of tastants.
FAQs
Population growth can accelerate when successive life-cycle stages progress successfully: egg masses survive winter, larvae hatch and feed in spring, pupae develop, and adults reproduce. Each stage presents different biological conditions and vulnerabilities. Tracking these transitions helps researchers determine whether a population is likely to remain limited or contribute to a damaging forest outbreak.
Larvae possess chewing mouthparts and actively consume leaves, making them the principal feeding stage responsible for defoliation. Adults instead contribute primarily to reproduction, so they do not produce the same direct loss of foliage. This distinction helps biologists connect larval abundance with immediate effects on deciduous trees and forest condition.
Outbreak intensity reflects interactions among population growth, available host plants, predators, pathogens, and environmental conditions. Abundant suitable foliage can support more feeding larvae, while predators or pathogens may limit population expansion. Studying these influences together is important because no single factor fully explains why defoliation becomes extensive in some forest situations.
Monitoring follows the species through its recognizable stages, including overwintering egg masses, spring hatching, larval feeding, pupation, and adult reproduction. Researchers can compare observations across these stages with host-plant availability and environmental conditions. This biological timeline provides context for identifying population increases, anticipating potential defoliation, and evaluating changes in forest ecosystems.
It is especially useful when managers need to detect rising populations, assess the likelihood of tree damage, or understand the ecological consequences of widespread defoliation. Information about predators, pathogens, host plants, and environmental conditions supports decisions about monitoring and invasive-species management. The same evidence can also guide efforts to reduce damage to deciduous trees.
Large-scale defoliation provides a way to examine how insect feeding alters forest ecosystems. Researchers can investigate effects on tree condition, relationships between host-plant availability and population growth, and the balancing influence of predators, pathogens, and environmental conditions. These observations connect the moth’s biology with broader questions about forest resilience and ecosystem change.
