Mastruz powder use (Chenopodium ambrosioides L.) for Alphitobius diaperinus (Panzer, 1797) (Coleoptera: Tenebrionidae) control in aviary

Abstract

This work evaluated the bioinseticidal effect on Alphitobius diaperinus. The efficiency of Chenopodium
ambrosioides L. powder at different concentrations (0; 0.25, 0.5, 0.75, 1.0 g cm-2)
and evaluation periods (7, 14, 21 and 28 days) at the Phytosanitary Laboratory of CDSA /
UFCG was studied. The experimental unit was built similarly to poultry litter. In the plastic recipients
of 6 x 5 cm (30 cm2) the C. ambrosioides powder was placed bellow of the rice husk in a
2cm layer. Additionally a poultry feed was added. Thirty adult insects were used per repetition.
Alphitobius diaperinus cumulative mortality and the efficiency (Abbott, 1925) were calculated.
According to the results, we concluded that Chenopodium ambrosioides powder at 1.0 g / cm2
was the most efficient concentration.
