Which is the effective biopesticide to control thrips on mango?
Kisan (2012) evaluated the efficacy of different entomopathogenic fungi on mango thrips. The results of the entomopathogenic fungi and botanicals on thrips ten days after application revealed that the maximum mean mortality of 90.00 per cent was recorded in treatment (T3), Verticillium lecanii @ 109 cfu/ml and was found to be the best treatment. The treatments V. lecanii @ 5 g/l (T7), Beauveria bassiana @ 109 cfu/ml (T6), B. bassiana @ 5g/l water (T9), V. lecanii @ 108 cfu/ml (T2), B. bassiana @ 108 cfu/ml (T5) and Ritha extract @10 per cent (T14) recorded 86.67, 83.33, 81.67, 80.00, 78.33 and 76.67 per cent mortality of thrips respectively.

If you don't want to use any chemical method to control thrips then you have to do few practices to get rid of thrips :
1. remove weeds and grass from around garden areas to eliminate alternate hosts.
2. Clean up crop debris in the garden, especially onion leaves after harvest. (Dry mulch will not attract thrips. Green mulch will.)
3. Blue sticky traps are helpful for monitoring adult populations. If found, use the Bug Blaster to hose off plants with a strong, encompassing spray of water to reduce pest numbers.
4. Release commercially available beneficial insects, such as minute pirate bugs, the effective thrips predator (feeds on eggs and larvae before they can become adults), ladybugs, and lacewing, (especially effective in green houses) to attack and destroy all stages of this pest. For best results, make releases after first knocking down severe infestations with water spray or other method.
5. BotaniGard ES is a highly effective biological insecticide containing Beauveria bassiana, an entomopathogenic fungus that attacks a long-list of troublesome crop pests – even resistant strains! Weekly applications can prevent insect population explosions and provide protection equal to or better than conventional chemical pesticides.
6. Severe populations may require a least-toxic, short-lived botanical insecticide (pyrethrin) to reduce pest numbers. Follow-up with predatory insects to maintain control.
Safe, smothering insecticidal soaps made from naturally occurring plant oils and fats, are also effective for knocking down heavy infestations (and won’t harm most naturally occurring beneficial insects). Spinosad and neem oil can be used to spot treat heavily infested areas.
