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.

Physiological parameters measured for Anticarsia gemmatalis larvae. The larvae were fed on a control diet or diets containing LbAE for 16 days. (A) Diet consumption by larvae (in mg, based on dry mass). (B) Mean food consumption as a ratio of the mean larval weight. 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.

Mentions: The larvae reared on an LbAE-containing diet consumed ∼ 47% less food than the controls (Figure 3A). However, when food consumption was expressed as a ratio of body weight, the larvae fed with LbAE consumed 25% more than the controls (Figure 3B). LbAE had a toxic effect when ingested by larvae (Table 2). LbAE, when incorporated in an artificial diet at 10 g/L, reduced ECI and ECD and creased the MC and AD for larvae when compared with the control.
