Early Warning for FAW Incidence (Announced on PPD website -www.ppdmyanmar.org)
“Fall Armyworm (FAW) Workshop in Myanmar”
Organized by PPD of Department of Agriculture and CABI on 5th December 2018
• Discussion on risk prediction
map of FAW based on favorable
environment
• Many places in Shan States,
Sagaing, Mandalay, and Nay Pyi
Taw Region, and some place in
Kachin and Chin States are
>50%Global Index
4
❖ The first recorded in Nay Pyi Taw, Tatkon and Myingyan.
The infestation was observed maize growing areas in winter season
❖ Collected Larvae were reared in the laboratory to confirm as FAW with
the assistance of some international organization. It was officially
announced the presence of FAW in Myanmar to IPPC in Jan 2019.
• FAW is reported in a majority of all maize growing areas in -2019 and
rapid spread in Myanmar

USAID’s activities:
Need assessment, monitoring and IPM management plan with
international experts (MSU, Mexico, S. Africa, India)
SAWBO scouting video clips translated own language !

USAID’s activities:
Southeastern Asia fall armyworms are
closely related to populations in Africa
and India, consistent with common origin
and recent migration

Molecular identification for Fall armyworm larvae,
The most preferable in Maize and this strain is confirmed Maize strain by MSU .

CABI’s activities:
• Mass extension and
communication campaigns in
support of national response
plans,
e.g. as part of Plant-wise
• Reviewing evidence for policy
and scientific decision making
10Implemented in terms of Research, Extension, Pest
Management and Awareness
( CABI, FAO, CIMMYT, USAID,YAU,DAR and Stakeholders)
11FAO’s activities:
TOT training for FAMEWS App.
with Dr Keith Cressman by Skype
meeting
FAMEWS App. are translated
own language !FAMEWS, an efficient monitoring system
in Myanmar established
• Trained central-level Staffs (TOT)
• Trained (60) extension and PPD staffs from
43 Townships main maize growing areas
• FAW presence can be monitored and
disseminated early warning information to
farmers
• Also shared into FAW Global platform
13High level meeting to obtain official commitment in use of FAMEWS
14Types of pheromones Traps and lure Early detection is the effective to control of Fall Armyworm
Collected moths with
pheromones trap
16FAW ICT materials for extension
staffs, PPD staffs and FAW
infested farmers
Use ICT / Social media is more effectively as a compliment
- 10,000 IPM Manuals
- 20,000 Pamphlets
but limited use for the smallholder farmers..
- 600 Vinyl posters 17Awareness among all stakeholders on FAW infestation in
Myanmar increased
FAW IPM trainings
Key farmers received FAW IPM trainings in
targeted areas of Myanmar
Training contents covered as follows;
- FAW detail biology and damage symptoms
- FAW monitoring and scouting
- Integrated FAW Management
- Natural Insecticides Production
- Safe use of Pesticides
18Efficacy of Different (Biological and Botanical) Insecticides against
Fall Armyworm (FAW) on Maize in Lewe township, Nay Pyi Taw
Treatment Insecticides
T1 B.t aizawai (4%WP)
T2 B.t kurstaki (8% W/W)
T3
Neem extract (Neem Seed Kernel Extract) (0.75% WS)
T4 Neem oil (0.03% EC)
T5 Tobacco extract
T6 Spinetoram (Endure 60 SC)
T7 Emamectin Benzoate (5% W/W)
T8 Control 19Most Effective Intercropping: Maize + Cowpea + Napier border
1. Maize+ Cowpea+ Napier Grass
2. Maize+ Mungbean + Napier
Grass
3. Maize+ Soybean + Napier Grass

5. Maize Only

• Enhancing awareness program, knowledge and skills
• Monitoring and Scouting for early detection with Pheromones
• Awareness raising with communication materials (leaflets, Journals, media..)
• Provision of bio-pesticides & personal protective equipment (PPE) for
emergency use
• Mass production of Eggs parasitoids Trichogramma wasps and released in
early plants stage
• Survey for the beneficial insects in Maize field
22Survey for natural enemies
Trichogramma spp.
Ecto-Larva parasite
Eulophidae; Euplectrus spp.
Telenomas spp.

Source – Nyaungdon townshipLarva parasite on Fall armyworm Braconidae; Habrobracon hebetor (Ectoparasite)
Natural enemies on Fall armyworm Entomopathogenic fungi
Ichneumonidae; Predatory Bug
Infected by Nomuraea
25 rileyiPredators in Maize crops
Following the IPM intervention
• Synchronized planting
• Plant population 20000/ac (Irrigated Maize)
25000/ac (Rainfed Maize)
• Intercropping with cowpea
• Use the pheromones traps 10 traps/acre (Control action)
• Released the eggs parasitoids 40000/ac (2 times)
• B.t spray after 5 days released Trichogramma spp. (OR)
• Spray Neem oil after 10 days released Trichigramma spp.
• Bird perches 10/ac
• Crushing egg masses and larvae

30How can we support farmers to improve
management of FAW
Provided more specific guideline for pesticides use
Well organized with farmers learning center
Strengthen farmers feedback mechanism for
motivated extension
Reconsider farmer group model ( Collaboration, farmer
participatory approach and innovation)
31Challenges faced for next step
Farmer familiar with highly toxic insecticides and management
practices should be used consistently and correctly by farmers
Farmer friendly technology approach identified and
validated by IPM demonstration plots
Should be recommend with efficient use of soft pesticides in
young larvae stages.
More awareness using with biopesticides and augmentation of
the beneficial insects
32Challenges faced for next step
Diversity and host range of fall armyworm
Status and socioeconomics of fall armyworm
Tools and techniques for surveillance, monitoring and
reporting
Mass production of feasible bio-control agents
Highly important: Natural biological control, fertilization, Plant
density, rain, also compensation of Maize plants,
33On-going Project !
Strengthening inter-regional cooperation for
sustainable management of fall armyworm
through South-South Cooperation (FAO-SSC)
ASEAN Action Plan on Fall Armyworm
Control
Collaborative research on IPM
