Hello Dear

A few leafrollers are nothing to worry about; you can easily cut the few damaged leaves from your plant and toss the caterpillars into a bucket of soapy water. Carefully pick through infested plants and those nearby to ensure you’ve gotten all the caterpillars, and check back weekly. Leafrollers don’t hatch all at once, especially if more than one species is present.

When numbers are very high, you may need chemical help. Bacillus thuringiensis works as a stomach poison to feeding caterpillars, and is extremely effective if applied to these pests and their food source while they’re young. It can be difficult to get sprays inside the rolled up nests, but if you can’t simply cut the caterpillars out, this is the next best option if you wish to preserve the natural enemies of the leafrolling caterpillars in your landscape.

Dear Prof. Houda Kawas,

Thanks so much your useful information.

Hi Sri  Banana skipper butterfly is a invasive pest..it has been effective controlled in Guam, Hawaii and in Papua New Guinea effectively using its larval parasitoid  Cotesia erionotae (Hymenoptera:Braconidae).This parasitoid will control the pest effectively. If you need more information about it please use www.cabi.org or or google the pest using google scholastic. here is a literature that you can consult: Sands,DPA;Bakker P and Dori FM 1993 Cotesia erionotae (Wilkinson) (Hymenoptera: Braconidae) for biological control of banana skipper butterfly Erionota thrax (L) Lepidoptera: Hesperidae in Papua New Guinea. Micronesica No:4 Suppl:99-105

i hope will help you to develop a Biological control method.

Cheers

Dear Prof. Errol Hassan

It takes a long time  since I'm leaving your laboratory in UQ Gatton at December 2011. How are you Professor? I hope you doing fine.

Yes Professor.....in my working research, farmers ignore presence of Erionota's immature stages. As I look in field,  they have contribute decrease quality of banana (be smaller) and reduce photosynthesis processed by leaves. At the moment, nothing control effort for Erionota. 

Thank you very much your answer. I'm highly appreciate it. I hope will develop biological control method to manage Erionota as soon as possible. GBU Professor ....

best regards,

Sri
