Area of Science:

• Entomology
• Insect Rearing
• Pest Management

Background:

• The Brazilian Poplar Moth (Condylorrhiza vestigialis) significantly impacts poplar wood productivity, particularly in Brazil's matchstick industry.
• Limited information exists on effective rearing techniques for this economically important pest.

Purpose of the Study:

• To develop an artificial diet for Condylorrhiza vestigialis that supports biological characteristics similar to wild populations.
• To facilitate bio-ecological studies and biological control programs, including those using Condylorrhiza vestigialis multiple nucleopolyhedrovirus (CvMNPV).

Main Methods:

• Three artificial diets were initially tested to identify nutritional adequacy.
• The most successful artificial diet (Diet 3: corn, wheat germ, yeast) was compared against the moth's natural diet.
• Life-table data and egg viability were assessed for both rearing conditions.

Main Results:

• Diet 3 successfully supported the completion of the C. vestigialis life cycle.
• Artificial diet resulted in 81% egg viability, significantly higher than the 40% on the natural diet.
• The net reproductive rate (Ro) was 401.70 on the artificial diet versus 151.22 on the natural diet.

Conclusions:

• The developed artificial diet is suitable for mass rearing Condylorrhiza vestigialis.
• This diet provides a foundation for advancing biological control strategies against this poplar pest.
• The findings support the use of this diet in baculovirus-based pest management programs.
