Section 4 • Integrated Insect and Rodent Pests Management
MECHANICAL OR PHYSICAL CONTROL OF INSECT PESTS
Highlighted in this sub-section are exercises depicting several best practices and experiences
by FFS farmers in performing simple and practical mechanical or physical control options.
These include handpicking (e.g., if dealing with few plants or pests), bagging (e.g., using
indigenous bagging materials to control fruit flies), using trap crops (e.g., pigeon pea to trap
earworm and Indian mustard to trap DBM), light traps (e.g., UV lights to trap a wide range of insect
pests), yellow sticky traps (e.g., trapping aphids and leaf miners), and sex pheromones (e.g., for pest
monitoring and regulating insect pest populations).
