An investigation was carried out on the larvicidal efficacy of four indigenous plant extracts against the 6th instar larvae of red flour beetle, Tribolium castaneum (Herbst) during the period of February to July 2016. The result revealed that all the four plant extracts were effective in checking insect infestation and had different toxic effects against the 6th instar larvae of red flour beetle. Average mortality indicated that castor plant extract showed the highest toxic effect (average mortality 57.78%) whereas the lowest toxicity (average mortality 27.46%) was found in the neem leaf extracts. The larval mortality significantly differed among all the concentrations of the plant extracts applied and the highest mortality (60.75%) was recorded in maximum concentration (10.61 mg/cm2) of the plant extract. No larval mortality was observed in untreated control up to 72 HATs. Mortality percentage was also observed directly proportional to the level of concentrations of plant extracts and to the exposure period. Probit analysis of larval mortality also revealed that the castor plant extract showed the highest toxicity at different time interval among all the plant extracts applied. Asiat. Soc.

Experiments were carried out to evaluate the toxicity of six botanicals, Bazna (Zanthoxylum rhetsa), Ghora-neem (Melia sempervirens), Hijal (Barringtonia acutangula), Karanja (Pongamia pinnata), Mahogoni (Swietenia mahagoni) and Neem (Azadirachta indica) against red flour beetle, Tribolium castaneum Herbst. Leaf and seed extracts were prepared by using acetone, methanol and water as solvents. The results showed that extracts of all the six plants had direct toxic effect on red flour beetle. Among them, Neem seed extract showed the highest toxic effect (mortality, 52.50%), whereas Hijal leaf extract possessed the lowest toxic effect (mortality, 22.24%). Among the solvents, acetone extract showed more toxic effect than other extracts. Seed extracts of respective plants were slightly more toxic than leaf extract. The effectiveness of most of the plant extracts increased proportionally with the increase of doses and decreased with time.

Abstract Background The red flour beetle, Tribolium castaneum (Herbst) (Coleoptera: Tenebrionidae), is a serious pest of stored grain commodities worldwide which results in considerable losses to stored wheat, Triticum aestivum (Linn.). Main body The present laboratory bioassay was carried out to examine the efficiency of the fungus, Beauveria bassiana (Bals.) formulation (Racer TM), and Neem extract (NE), Eucalyptus extract (EE), and Tobacco extract (TE) against 3rd instar larvae of T. castaneum. The fungal formulation was applied at 0.3 × 108, 0.6 × 108, and 0.9 × 108 conidia kg−1 of the crushed wheat grains; as well, it was mixed separately with 5% concentrations of each plant extract under the laboratory conditions of 30 ± 2 °C and 65 ± 5% RH. Mortality rate of the tested larvae was enumerated after regular intervals of times. Mortality of the larvae increased at the highest combined concentrations of the fungal conidial formulation and the plant extracts rather than their single treatments. The highest mortality rate of the larvae (71.32%) was recorded at the highest concentration binary mixture of (Racer TM +NE), whereas relatively the lowest mortality rate (15.54%) was enumerated in the combined treatments of (Racer TM +NE). Furthermore, the highest separate concentration of B. bassiana (0.9 × 108 conidia/ml) persistently resulted in more larval mortality (32.68%) of 3rd instar larvae of T. castaneum than the plant extracts (7.52, 9.89, and 14.61%), respectively. A noticeably greater rate of mycosis and sporulation was counted in the larvae of the insect in separate treatments of B. bassiana than in its combined applications with the plant extracts. The highest mycosis (85.13%) and sporulation (160.12 conidia/ml) was detected in the treatment, where the lowest concentration of B. bassiana (0.3 × 108 conidia/ml) was used, alone. Conclusion Hence, it was concluded that integrated use of these two bio-pesticides plus the fungus can be helpful in the integrated pest management program of T. castaneum.

The red flour beetle Tribolium castaneum (Hbst.) is the most destructive pest of the stored grains and responsible for causing the tremendous loss to stored grains depends upon the storage structures and conditions. It deteriorates the quality and quantity of the stored grains. The current study was carried out to monitor the level of resistance in red flour beetle against phosphine and deltamethrin. Six concentrations of phosphine (0.006, 0.007, 0.008, 0.009, 0.01 and 0.011 ppm) and deltamethrin (0.01, 0.02, 0.03, 0.04, 0.05 and 0.06 ppm) were used against this test insect. The mortality data of this insect against phosphine was recorded after 7, 14 and 21 days of treatment. The data regarding mortality (%) was recorded after 24, 48 and 72 hours. The results showed that the maximum mortality of resistant and susceptible strain of T. castaneum against deltamethrin at 0.06% was 38.78% and 72.52% respectively. The maximum mortality of resistant and susceptible strain of T. castaneum against phosphine at 0.011 ppm was 74.46% and 76.81% respectively. All the data showed that Tribolium castaneum was 4.86 times fold resistant against deltamethrin after 72 hours’ time interval than over susceptible strains. The LC50 value showed that T. castaneum was 0.75 times fold resistant against phosphine after 7 days’ time interval than over susceptible strains

Five-day old larvae of the susceptible (FSS-II) and organophosphorus-resistant (PH-I) strains of the red flour beetle Tribolium castaneum were exposed under laboratory conditions to food treated with 100, 250, 500 and 1000 ppm of a synthetic pyrethroid Fenvalerate up to adult emergence. The larval mortality was assessed at 1-, 3-, 7- and 15-days post-exposure, and up to pupation. PH-I was found less susceptible to Fenvalerate than FSS-II which required 1.2 to 3.1 fold more insecticide to induce 50% mortality. The pyrethroid treatments significantly increased the larval and pupal periods (P<0⋅05) in both the strains and the formation of pupal and adult progenies was adversely affected (P<0⋅001).

Toxicity, repellency and residual effects of Bishkatali plant extracts in chloroform and ethyl alcohol solvents were evaluated against the red flour beetle. Five concentrations viz. 500, 250, 125, 62.5 and 31.25mg/ml of Bishkatali plant extracts of both solvents were used in the experiment. The plant extracts in both solvents were moderately toxic to Tribolium castaneum. The toxicity of ethyl alcohol extract was more than chloroform extract after 24 and 72 hours treatment on the insect. Bishkatali plant extract in both solvents showed strong repellency against T. castaneum in which chloroform extract was better than ethyl alcohol extract. The rate of repellency was increased with the increment of concentration. Both the extracts have produced remarkable residual effect in reducing the progeny of T. castaneum. The lowest numbers of F1 adult progeny (32.7, 25.3 and 27.0) emerged from the wheat flour treated with 500mg/10g chloroform extract when parent released at 7, 12, 17 days after treatment respectively. Whereas with 500mg/10g ethyl alcohol extract, 38.0, 29.7 and 30.3 F1 adult progeny emerged when parents released at 7, 12, 17 days after treatment respectively. Bishkatali plant extracts in both chloroform and ethyl alcohol had remarkable residual effects on T. castaneum by reducing the production of F1 progeny and/or by increasing the population mortality.
