Integrated Approach For Management Of Leaf Miners In Crops

Leaf miner is one of the serious pests that attack a wide range of crops including vegetables, fruits, ornamentals and cause economic yield loss. Larva is the attacking stage of the pest that causes damage to leaf tissues, reducing photosynthesis and ultimately reducing the yield and quality of crops. They are typically small maggots that range in colour from yellow to green or brown. They have piercing and sucking type of mouthpart that allows them to scrape and feed on the plant’s tissue. The feeding activity of the larvae creates distinctive trails or tunnels on the surface of the leaf, which can vary in shape and size depending on the species of leaf miner. 

Leaf miner infestation can cause significant damage to crops affecting their growth and yield. Effective management of leaf miners requires timely detection and a combination of several control measures to reduce their impact on the crop. 

Different Species of Leaf miner: 

  • Liriomyza spp. – This genus of leaf miner is one of the most destructive and widely distributed. They attack a wide range of crops, including beans, peas, tomatoes and ornamental plants. Liriomyza huidobrensis, Liriomyza trifolii and Liriomyza sativae are some of the most common species
  • Chromatomyia horticola. – This is a major pest of many vegetable crops like beans, peas and potato  
  • Tuta absoluta – It is a major pest of tomato crop causing extensive damage and reducing yield due to larval feeding on leaves, stems and fruits of tomato plants 
  • Phyllocnistis citrella – This is citrus leaf miner that infests citrus plants 
  • Pegomya hyoscyami – This is Spinach leaf miners which infests on Spinach and Radishes 

Host crops: 

Leaf miners infest a wide range of plants, including vegetables, fruits and ornamentals. Tomato, potato, okra, citrus, spinach, pepper, peas, beans, beets, cucurbits and crucifereous vegetables are the commonly affected crops. 

Symptoms of Leaf miner infestation in crops: 

  • Larva feeds on the internal tissues of the leaves by creating shallow tunnels or trails that appear as discolored or brown patches on the leaf surface 
  • Leaves curl due to the mining activity of larva in the lower or upper surface of the leaves 
  • Infested leaves may appear pale or yellow and in severe cases, they may turn brown and wither 
  • Leaves of the affected plant becomes distorted or shriveled 
  • Severe leaf miner infestations can cause stunted growth of the affected plant, leading to reduced yields and poor-quality produce 
  • Causes drying and pre-mature dropping of affected leaves 
  • The feeding activity of the larva can weaken the plant, making it more susceptible to other pests and diseases like citrus canker due to secondary source of infection. 

Favourable conditions for Leaf miner incidence: 

Warm temperature, high humidity, presence of host crops, monoculture cropping, presence of plant debris, excessive use of pesticides can favour leaf miner infestation.  

Preventive Measures: 

  • Maintain field sanitation by removal and destruction of the infested leaves and crop debris 
  • Using sticky traps help to detect leaf miner activity early and allow for timely intervention 
  • Release of biological control agents such as parasitic wasps and predatory insects can be used to control leaf miner populations 
  • Spraying neem oil on the leaf surface 
  • Optimum use of fertilizers  
  • Avoid water stress conditions in the field because it can weaken the plants 
  • Crop rotation with non-host crops 
  • Reflective mulch 
  • Regularly monitor the crops for any signs of leaf miner infestation in weekly interval

(NOTE: Presence of eggs and larvae in leaf, pupae in soil and adult on plants are needed to be killed in integrated methods for effective control of leaf miners. Insecticides with translaminar or systemic mode of action can be used to control leaf miner. Please check the product label before use to know the right time of application) 


Leaf miner can cause reduced plant growth, reduced yield and premature leaf drop which can affect the overall productivity of the crop.  Integrated management of leaf miners in crops involves a combination of preventive and management measures that can effectively control leaf miner infestations and minimize crop damage. Preventive and biological control measures can be used to detect and control infestations at an early stage. In severe cases, chemical control may be necessary, but it should only be used as a last resort and with caution to prevent harm to beneficial insects and pollinators.
