Insect Pest Management: Options for Controlling Pest Populations

Stacy Swartz

Excerpt:

Mechanical interventions for pest control are generally categorized as passive or active. Passive options include films, dusts, oils, soaps, and traps. Films such as kaolin clay can deter insects from landing on plants and/or deter feeding behaviors, but such films need to be reapplied as the plant generates new growth. Dusts such as diatomaceous earth can be placed around the base of plants to keep crawling pests from accessing the plant. Dusts can also be placed on the leaves as a feeding deterrent. Oils and soaps that kill pests are physical controls because their effect is short-term, and they act physically on the pest by smothering them or breaking down sensitive exterior tissues. Oils and soaps must contact pests and are most effective against soft-bellied insects such as aphids, mealybugs, whiteflies, spider mites, and scales. Repeated application is often required to control a population because oils and soaps are most effective at controlling young individuals.

TN #97 Small-Scale Nursery Management
Cultivating plants, sharing seeds and cuttings with neighbors, and seeking better crop varieties are as old as agriculture. We use the word “nursery” for places where we care for and nurture things that are precious and vulnerable, like children and plants. Creating habitats to grow healthy seedlings is an integral part of the farming cycle, an important contribution to a thriving community, and both a rewarding and challenging business opportunity. A nursery can be as small as a farmer’s seedbed for the immediate planting of a single crop, or as large as a complex business with hundreds...

BPN #2 - Farmer-Centered Climate Change Mitigation
ECHO recognizes climate change as a profound reality faced by small-scale farmers. Many of our publications have focused on helping farmers cope with related challenges such as heat and drought.Increasing farmer resilience and minimizing risk have been key elements of the practices we have written about over the years.  We encourage “no regret” strategies, approaches that steward the land well and improve livelihoods, regardless of whether or not farmers face immediate changes to climate. However, we also view farmers as having an integral role in mitigating some of the driving forces of...

TN #96 Earthbag Seed Banks
Seed storage in the tropics has been a frequent topic of ECHO publications and trainings due to its importance to the smallholder farmer. Access to quality seeds is imperative for agronomic and horticultural crop production. While on-farm seed saving benefits the smallholder farmer, cooperative seed storage through the creation of seed banks bolsters farmers at the community level. Seed banks provide secure structures for seed storage, while also serving as genetic repositories for important plants in the community. Centralizing the seed saving process also allows for cooperative...

TN #95 100-Fold Vegetable Gardens with Low-Cost Wicking Beds
I discovered 100-fold gardens while researching ways to irrigate plants directly in the root zone. I wanted to know how to practically and affordably control some of the variables that influence plant growth, such as water availability and soil fertility. I read about “wicking beds,” which are watered from below as water moves up towards plants’ rooting zone from a reservoir lined with plastic. Watering from below prevents water loss while maintaining constant soil moisture and supplying water and nutrients in accordance with plant needs.  Wicking beds are a way of maximizing vegetable...

TN #94 Parasitic Plants in African Agriculture
This Technical Note provides an overview of parasitic plants of agricultural significance in Africa. Parasitic weeds cause drought stress and stunted crops. Affected plants include cereal grains (e.g., sorghum [Sorghum bicolor] and maize [Zea mays]) and grain legumes (e.g., cowpea [Vigna unguiculata]) that farmers rely on for food. Damage to these and other crops is generally heightened by low soil fertility and drought stress, conditions that are faced by many African smallholders. Parasitic weeds can lead to severe yield losses, making them an important constraint to food security in many...

TN #93 Vacuum-Sealing Options for Storing Seeds
Two broad categories of seeds exist, referred to as recalcitrant and orthodox. The former must be kept moist and planted soon after they are collected; large-seeded fruits such as mango and avocado are typical examples. The second type of seeds are discussed in this document. Orthodox seeds are generally smaller than recalcitrant seeds and represent almost any grain, legume, or vegetable crop. Orthodox seeds can be dried and stored for extended periods of time—often for many years, depending on the crop and storage conditions. This document presents ways to remove air from seed...
