Chemical Cues for Targeted Pest Monitoring: A New Frontier in Horticultural Pest Control

Identifying and synthesizing specific volatile organic compounds emitted by host plants can lead to the development of novel lures for monitoring and potentially controlling agricultural pests.

Greenwich Academic Literature Archive (University of Greenwich) · 2015

Key Findings

01Gravid raspberry cane midge females are attracted to split canes for oviposition, and specific chemicals are present in higher quantities after canes split.
02Initial field tests with raspberry cane midge lures showed no significant attraction to males or females.
03Volatile compounds from blackcurrant shoots were identified, but bioassays in olfactometers and wind tunnels did not show significant female attraction.
04Electroantennography (EAG) did not yield conclusive results for identifying EAG-active compounds in blackcurrant leaf midges.

Application

Design takeaway

How to apply

When designing pest management tools, consider conducting extensive sensory studies, including olfactometry, wind tunnel experiments, and potentially exploring pheromones or other attractants in conjunction with host plant volatiles. Iterative testing and refinement of lure composition and delivery systems are essential.

Project actions

01When investigating attractants, consider testing a range of concentrations and combinations of chemicals.
02Document all environmental conditions during field trials, as these can significantly impact insect behavior.

Method & Evidence

AimCan specific volatile organic compounds emitted by host plants be identified and synthesized to create effective lures for monitoring gravid female gall midges in horticultural crops?

MethodChemical analysis and bioassays

ProcedureThe study involved identifying volatile chemicals emitted by split raspberry canes and blackcurrant shoots using Solid Phase Microextraction (SPME). These identified chemicals were then tested as potential attractants for raspberry cane midge and blackcurrant leaf midge females using field traps, olfactometers, and wind tunnels. Electroantennography (EAG) was also used to assess the antennal response of blackcurrant leaf midges to volatile extracts.

ContextHorticultural pest management, specifically focusing on gall midges affecting fruit crops.

Variables

IVChemical composition of lures (based on identified plant volatiles)

DVAttraction of gravid female midges (measured by trap catches, olfactometer choice, wind tunnel behavior)

CVHost plant species, trap type, environmental conditions (wind, temperature, humidity), time of day

Strengths & Limitations

Strengths

+Utilized advanced analytical techniques (SPME) for chemical identification.
+Employed multiple bioassay methods (field traps, olfactometer, wind tunnel) to assess attraction.

Limitations

The study's limitations include the lack of conclusive attraction, the potential for identified chemicals to be only minor contributors to attraction, and the inconclusive EAG data.

Reliability & validity

The reliability of the findings is questionable due to the lack of significant attraction. Validity could be improved by increasing sample sizes, standardizing environmental conditions more rigorously, and exploring a wider range of chemical compounds and their combinations.

Think critically

Given the lack of significant attraction, what other factors beyond volatile organic compounds might influence the gravid females' host plant location and oviposition decisions?

Design Principles

"Insect attraction is often mediated by complex chemical signals, and successful lure design requires a comprehensive understanding of the pest's sensory biology and ecological interactions."

This research explores the potential for developing targeted pest management strategies by understanding the chemical communication between pests and their host plants. Such insights can lead to more precise and environmentally friendly pest control solutions, reducing reliance on broad-spectrum pesticides.

What This Means for Your Design

Scientists tried to make a special 'smell' to attract fruit-eating flies to traps, but it didn't work as well as they hoped. This shows that making something attractive to insects is tricky and might need more than just one smell.
