Entomocidal effects of beech apricot, Labramia bojeri, seed extract on a soybean pest, the velvetbean moth, Anticarsia gemmatalis, and its enzymatic activity.

Macedo ML, Kubo CE, Freire MG, Júnior RT, Parra JR - J. Insect Sci. (2014)

Bottom Line: The effects of the beech apricot, Labramia bojeri A. de Candolle (Sapotales: Sapotaceae), seed aqueous extract on the larval development of the velvetbean moth, Anticarsia gemmatalis Hübner (Lepidoptera: Noctuidae), was evaluated.Larvae fed 10 g/L of the aqueous extract showed a significant reduction in trypsin activity (~64%), when compared with control larvae.The results from dietary utilization experiments with A. gemmatalis larvae showed a reduction in the efficiency of conversion of ingested food and digested food and an increase in approximate digestibility and metabolic cost.

Effect of dietary LbAE on Anticarsia gemmatalis larval mass (A) and survival (B). Effects of 10 g/L LbAE on larval development time (C). Insert: variation in the size of 4th instar A. gemmatalis larvae fed 10 g/L LbAE (right) and control (left) diets. Ruler = cm. Bars indicate standard error of the mean. The same letters indicate that there were no significant statistical differences (Mann-Whitney U test, n = 50, p = 0.05). High quality figures are available online.

The same letters indicate that there were no significant statistical differences (Mann-Whitney U test, n = 50, p = 0.05). High quality figures are available online.

Mentions: Larvae fed on diet containing 10 g/L LbAE produced an approximate 50% decrease in weight (Figure 1A). LbAE of up to 20 g/L caused ∼ 75% decrease in larval weight (Figure 1A). Treatment containing aqueous extract at 10 g/L and 20 g/L reduced survival by about 50% (Figure 1B). However, 10 g/L LbAE did not significantly affect larval development time (Figure 1C).
