Introduction: Millions of people consume rice daily and it’s one of the most consumed

products worldwide. Nowadays, weevils are causing many problems to rice producers and they are

losing tons of product. The factor that has caused the greatest growth is the global warming due to the

global increase temperature. Finally, the strategies used by the producers are not the most suitable, for

this reason, we will seek an effective solution to combat weevils.

Objectives

1-Find a microwave treatment that inhibits the growth of S.

oryzae larvae in rice.

2-Evaluate the growth time of S. oryzae, T. castaneum and O.

surinamensis.

Conclusions: 1-The main objective has not been achieved, however, in the specific objective we have obtained results.

2-Limitations: time, technology.

3-In the future, we can change the food used, which also implies a change in the weevil.

2-Time of growth between 24 and 29 days. 3-Time of growth between 33 and 39 days.

1-O. Surinamensis no growth.

In this first try, the applied energy was excessive. The applied energy has been reduced but there hasn’t been growth
