Secret weapon for NT mangoes

Entomologist Dr Austin McLennan says his fruit fly trials could revolutionalise the NT mango industry.

CHANGE could be afoot in the Northern Territory mango industry if entomologist Austin McLennan gets his way.

At the Katherine Research Station, Dr McLennan and his team are running trials to prove that local mangoes need not be sent to Queensland for expensive post-harvest spraying before export to Asia.

Despite the long-held belief that fruit flies are a significant pest for NT mangoes, Dr McLennan is seeking to demonstrate otherwise.

The reason is a simple one. While fruit fly infestations are abundant in ripe, yellow mangoes, rates of infestation in mature green mangoes are virtually non-existent.

Yet, the current protocols do not reflect this commercial reality.

“We’re trying to show that [fruit flies] won’t develop in the commercial type of mangoes grown in the Northern Territory, provided those mangoes are picked at the correct stage of maturity, which is the green, hard stage,”
Dr McLennan said.

“What’s driven a lot of the rules and regulations around fruit fly management, control and the requirements is the knowledge that mangoes can be a host, but most of the data is on them being a host at the soft, yellow, ripe stage, not the hard, green mature stage at which they’re picked.”

Dr McLennan’s trials involve putting a concentrated number of fruit flies in nets surrounding mangoes.

Even in these extreme circumstances, the research shows the flies are still not attracted to the green mangoes and will not lay eggs.

“My work over the last few years has shown that [rates of infestations in] hard, mature fruit is very low and, actually, when you do find it, it’s usually only in fruit that is blemished or damaged in some way, and would otherwise hit the reject bin anyway.”

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.
