Digestive α-amylase inhibition negatively affects biological fitness of the Indian meal moth, Plodia interpunctella (Hub.) (Lep: Pyralidae)

Impact of carbohydrase inhibition on Habrobracon hebetor in a tritrophic diet‐host‐parasitoid system

“…However, the impact on parasitoid physiology does not translate into an effect on parasitoid fitness. The effects on the parasitoid are attenuated compared to the effects of acarbose on the host insect as the results from the present study and our previous work (Masoumzadeh et al., ) demonstrated high impact of acarbose on P. interpunctella physiological and biological parameters.…”

“…High sensitivity of amylase from the bruchid Zabrotes subfasciatus (Boheman) (Grossi de Sa et al., ), the bug Podisus maculiventris (Say) (Ghamari et al., ), and the weevil Sitophilus zeamais Motschulsky (Lopes et al., ) to the inhibitor has been also reported. In our previous study we found high inhibitory potential of acarbose on α‐amylase activity, as well as effects of acarbose on weight, size, and physiological and biological parameters of P. interpunctella (Masoumzadeh et al., ).…”

“…Enzyme inhibitors such as α‐amylase inhibitors are appropriate candidates for protection of plants and their products against damage by herbivorous and granivorous insects (Gatehouse, ). The non‐proteinaceous α‐amylase inhibitor acarbose is known for its inhibitory effect on the carbohydrases of herbivorous and carnivorous insects (Hubert et al., ; Kaufnerová et al., ; Ghamari et al., ; Masoumzadeh et al., ). Acarbose is an anti‐diabetic drug that is obtained from fermentation processes of the microorganism Actinoplanes utahensis Couch (Wang et al., ).…”

“…Acarbose is an anti-diabetic drug that is obtained from fermentation processes of the microorganism Actinoplanes utahensis Couch (Wang et al, 2012). We previously showed that acarbose interfered with the function of carbohydrate digestion in P. interpunctella, and affected several biological parameters (e.g., larval and pupal weight, larval length, larval and pupal duration, larval mortality, adult longevity, fecundity, fertility, and oviposition period) (Masoumzadeh et al, 2014). In the current study, we investigate the inhibitory activity of acarbose on a-amylases of H. hebetor.…”

Evaluation of Plastic Packaging for Prevention of Damage to Wheat by Trogoderma granarium (Coleoptera: Dermestidae), and Suitability of Phosphine Fumigation

“…The choice of old-style storage structures, plus application of insecticides by farmers, often occurs because they are uninformed about improved techniques (Hall 1970). The negative effects of chemical insecticides include harmful effects on human health and environmental pollution, as well as development of resistance by the insect pests (Masoumzadeh et al 2014). Therefore, an alternative method of storage is needed.…”
