First Report of Tuta Absoluta (Meyrick) Zambia.
Name of Session: Pest Surveillance in Phytosanitary Systems Maimouna Saidi Abass Plant Quarantine and Phytosanitary Service Senior Agricultural Research Officer

Outline Introduction Methodology Results Discussion
Recommendation to phytosanitary science and conclusion
3
Introduction Tomato - top five crops dominating smallholder systems,86% of the total value of fresh fruit and vegetable sales Tuta absoluta Meyrick (Tomato Leaf Miner) (Lepidoptera: Gelechiidae) 2014 T. absoluta present in East Africa, reported in Tanzania, predicted moving southwards (Muniappan 2013) Pest initiated PRA conducted (high likelihood of introduction and spread) October Surveillance proposal in place - Russel IPM support January 2016 Training – PHIs Feb – Mar 2016 Preliminary Surveillance April Tanzania study tour
4
Methodology Survey: 11 districts of Zambia where the pest was reported. Target: Tomato farms and tomato market places. Survey Team: Plant Health Inspectors and Agricultural Extension staff Optima lure pheromone traps
5
Methodology cont’d Traps hang at a height of 1-1.5m
above ground from tomato stakes. Left for a minimum of one week the collected. Extension farmers trained Further farm visitations to collect the pest for identification.
6
Results Map of Zambia showing districts where Tuta absoluta was detected in April 2016.
7
Results cont’d a) Kafue District; Left: Infested field of tomato. b)Right: Bottom: Mines of T.absoluta on tomato leaves on a farm , Top: T.absoluta damage on tomato fruit at a farm in Kabwe.
8
Results ZARI experts identified T.absoluta.
Adult moth identified based on ; Key morphological characteristics; size, filiform antenna and black ashy bands on the forewings. Type of damage caused Catches on the pheromone traps The host plant Tanzania expert opinion
9
Discussion T.absoluta was present in all surveyed districts.
Inadequate funds for Tuta programs - limited area and scope for surveillance Central province showed high infestation compared to the other three provinces. high tomato producing area, tomato grown throughout the year. may have been no break in life cycle, pupation in the soil, constant food available (Chidege et al. 2016; Desneux et al. 2010; Desneux et al. 2011).
10
Discussion Cont’d Identification – Only by adult moth stage and not egg, larva and pupa. Due to; absence of appropriate rearing facilities and equipment in the Entomology laboratory lack of available funds to build this capacity. Method compares favourably with methods used in other countries for first reports on T.abslouta (Chidege et al. 2016; Kilin 2010; Pfeiffer et. al. 2013).
11
Discussion Farmers reported Some farms -90% damage of the crop.
low yields, high rate of infestation some resistance of the pest to pesticides had to mix a variety of pesticides to achieve this reduction. Some farms -90% damage of the crop. Continuous infestations facilitated by short distances between the farms despite crop rotation planting of alternate hosts i.e. green pepper poor management practices i.e. rotten tomatoes kept in field.
12
Discussion cont’d Presence of T. absoluta in the surveyed districts confirmed the outcome of the PRA conducted by PQPS high likelihood of pest introduction and its spread. spread attributed to several factors movement of both seedlings and wooden crates around the country due to the high demand for tomato. These pathways reported to contribute to the spread of the pest (CFIA 2010; Desneux et al. 2011; Muniappan 2013; NAPPO 2013).
13
Recommendation to phytosanitary science and conclusion
This is the first report of T. absoluta in Zambia. will help trading partners and scientists in the worldwide to carry out pest risk analyses. Recommendations Increase awareness creation - importance of IPM, appropriate use of pesticides and food safety to farmers. More collaboration on management of the pest and resistance studies between academic, field researchers and private sector. Regional Collaboration. More research on bio pesticides needed.
