An entomopathogenic nematode, Steinernema siamkayai
- A warm-adapted entomopathogenic nematode Steinernema siamkayai Tiruchirappalli strain can cause 45-100% larval mortality of various insect species including Galleria mellonella, Spodoptera exigua, Ceratitis capitata, Cydia splendana and Tenebrio molitor when tested under laboratory conditions at temperatures between 15- 37C (Raja et al., 2011).
- Wax moth (Galleria mellonella) larvae are pests of honeycomb but are widely used as a model organism for laboratory study and in vivo production of entomopathogenic nematodes.
- Beet armyworm (Spodoptera exigua) is a noxious pest of many crops including beets, asparagus, beans, different Cole crops, potatoes, tomatoes, sorghum, cotton and different oilseed. Larvae of beet armyworm feed voraciously on leaves and are known for complete defoliation of plant.
- Mediterranean fruit fly (Ceratitis capitata) is economically important pests of many fruit crops including citrus, peach, pear and apple. Fruit fly larvae feed inside the fruits and makes fruits unattractive for eating.
- Acorn moth (Cydia splendana) larvae mainly cause damage to oak and chestnuts.
- Mealworm (Tenebrio molitor) larvae are commonly used as feed for many pet animals such as fish, reptiles and birds. These larvae are also used to study and in vivo production of entomopathogenic nematodes.
