“…Many plant-derived materials have been proved as toxic and growth regulators against stored products insects (Cosimi et al, 2009). Plant lectins are biodegradable insecticidal agents that possessed deleterious effects on the survival, growth, oviposition and reproduction of stored grain insect pests (Oliveira et al, 2011). The leaf extracts of ghagra Xanthium strumerium revealed insecticidal effectiveness against C. chinensis reared on black gram grains.…”

The n-hexane extracts of the weeds 'bhatpata' Clerodendrum viscosum, 'kashiature' Cassia tora, 'dhakishak' Dryoptris filix-max, 'bonmorich' Croton bonpalandianum and 'ghagra' Xanthium strumarium were used to evaluate their effectiveness for suppressing pulse beetle, Callosobruchus chinensis reared on mung bean Vigna radiata grains. The investigations were done with 1, 2 and 4% n-hexane extracts of the weeds and an untreated control. The weed extracts exhibited considerable effectiveness which varied with weed species, concentrations and exposure durations. The higher concentrations showed the higher rate of insect mortality, fecundity, adult emergence inhibition, and grain protection. The LC50 values of the extracts ranged from 5.3 to 7.8, 4.7 to 6.5 and 4.1 to 6.0 g/100 ml at 24, 48 and 72 hours after treatment, respectively. The fecundity inhibition varied from 31.7 to 78.7%, adult emergence inhibition from 33.8 to 81.1%, and grain damage inhibition from 10.3 to 60.1% when 'bhatpata' with concentration of 1 g/100 ml and 'ghagra' with concentration of 4g/100 ml were applied, respectively. Among the tested weeds, ghagra (4g/100 ml) showed better efficacy against C. chinensis compared to other tested extracts and may be suggested to control pulse beetle and protection of mung bean grains.

“…The significant increase in the total development period and drastic reduction in percentage pupation and percentage emergence of adults could be due to anti-feedant effect of the lectins. Furthermore, being resistant to digestion in insect digestive system, lectins might alter the intestinal protein content creating nutritional imbalance leading to detrimental effects on developmental parameters (Oliveira et al, 2011). This effect of lectins can also be attributed to binding of lectins to carbohydrate moieties associated with the membranes of the gustatory chemosensory sensillae, thus blocking access to food chemical signals (Sprawka et al, 2014).…”

A lectin was purified from the tuber, Dioscorea mangenotiana in this study. The lectin agglutinated erythrocytes from human and rabbit, and the activity was inhibited by glucose and N-acetyl-Dglucosamine with minimum inhibitory concentration (MIC) of 50 and 25 mM, respectively. The lectin was composed of two isoforms, DML I and DML II. The apparent native molecular mass of DML I was estimated at 51 kDa and the subunit molecular mass at 25 kDa, suggesting a dimeric structure. The lectin was stable up to 90°C and within the physiological pH range. The lectin when incorporated in artificial diet at concentrations of 10 to 160 µg ml -1 and fed ad libitum to the second instar larvae of Eldana saccharina, prolonged the development period and significantly inhibited the pupation and emergence of the insect in a dose-dependent manner. The LC 50 calculated based on mortality after 72 h of treatment was 66.6 mg/ml. The activities of hydrolytic enzymes -acid phosphatase, alkaline phosphatase and acetylcholine esterase in the larvae reared on diet containing lethal dose of the lectin were significantly affected as compared to those fed on diet without the lectin. The results showed that DML I has promising anti-insect potential and could be employed in a biotechnological strategy for the pest management.
