Abstract



A field survey was conducted in Ataulfo mango (Mangifera indica L.) orchards in Chiapas, Mexico, with the objective of determining the natural enemies of the Frankliniella complex species (Thysanoptera: Thripidae). 



Seven species of this genus feed and reproduce in large numbers during the mango flowering. 


Two representative orchards were selected: 


the orchard “Tres A” characterized by an intensive use of agrochemicals directed against thrips, 

and 


the orchard “La Escondida” that did not spray insecticides. 





During mango flowering, five inflorescences were randomly collected every 5th day in both orchards, for a total of 18 sampling dates.



 Results revealed the presence of 18 species of arthropods that were found predating on Frankliniella. 


There were 11 species in the families Aeolothripidae, Phlaeothripidae, Formicidae, Anthocoridae and Chrysopidae; and seven species of spiders in the families Araneidae, Tetragnathidae, and Uloboridae. 


Over 88% of predators were anthocorids, including, Paratriphleps sp. (Champion), Orius insidiosus (Say), Orius tristicolor (White), and O. perpunctatus (Reuter). 



The orchard that did not spray insecticides had a significantly higher number of predators suggesting a negative effect of the insecticides on the abundance of these organisms.

While "Flavor" is very subjective, and each country that grows mangoes is very nationalistic, these are the mango varieties that are the most sought after around the world because of sweetnesss (Brix) and demand.

The Chaunsa has a Brix rating in the 22 degree level which is unheard of!
Carabao claims to be the sweetest mango in the world and was able to register this in the Guiness book of world records.
Perhaps it is time for a GLOBAL taste test ???

INDIA 2016 : Mango production in state likely to take a hit this year

TNN | May 22, 2016, 12.32 PM IST






Mangaluru: Vagaries of nature is expected to take a toll on the production of King of Fruits - Mango - in Karnataka this year. A combination of failure of pre-monsoon showers at the flowering and growth stage and spike in temperature in mango growing belt of the state is expected to limit the total production of mango to an estimated 12 lakh tonnes in the current season as against 14 lakh tonnes in the last calendar year.



However, the good news for fruit lovers is that this could see price of mangoes across varieties decrease marginally by 2-3%. This is mainly on account of 'import' of the fruit from other mango-growing states in India, said M Kamalakshi Rajanna, chairperson, Karnataka State Mango Development and Marketing Corporation Ltd.




Karnataka is the third largest mango-growing state in India after Uttar Pradesh and Maharashtra.
