“…The combination of DEs with natural products may enhance their DE's efficiency and decrease their adverse effects [13,18,29,36,44]. For example, DEs plus entomopathogenic fungi provided sufficient control against several stored-product insects [18].…”

“…SilicoSec and conidia of B. bassiana resulted in additive and/or synergistic effects against C. maculatus and O. surinamensis adults [29]. Beauveria bassiana combined with Celite or Sayan DEs reduced the fecundity, egg hatching, oviposition period, and longevity of Trogoderma granarium Everts (Coleoptera: Dermestidae) adults, more than each formulation alone [44]. Metarhiz-ium anisopliae plus Hudson DE were proved highly effective against Plodia interpunctella (Hübner) (Lepidoptera: Pyralidae) larvae vs. M. anisopliae or DE alone [43].…”

“…Interestingly, the combination of DEs with entomopathogenic fungi has been proven to enhance conidial attachment and their virulence [28,42]. Although, there are numerous reports about the combination of DEs and entompathogenic fungi [13,18,29,43,44], there is no published information regarding the efficacy of DE enhanced with abamectin and B. bassiana as stored-grain protectants. Therefore, the objectives of this study deal with the evaluation of DEA (DE + abamectin) combined with B. bassiana at different doses, to assess the radial fungus growth, mycosis, and sporulation, as well as the pesticidal activity of the aforementioned combinations against T. castaneum (larvae and adults), progeny reduction in adults on wheat after prolonged storage periods.…”

This study determined the efficacy of the Beauveria bassiana (Balsamo-Crivelli) Vuillemin (Hypocreales: Cordycipitaceae) alone or combined with the diatomaceous earth DEA (a mixture of DE + abamectin) against adults and larvae of Tribolium castaneum (Herbst) (Coleoptera: Tenebrionidae). DEA was evaluated at 50 ppm while the fungi at 1.6 × 105, 1.6 × 106, and 1.6 × 107 conidia/kg wheat). Mortalities were assessed after 7 or 14 days of exposure, while progeny reduction in adults after 30, 60, 90, or 120 days. The radial fungus growth was significantly affected by the dose of DEA. Mortalities were higher in the combined treatments compared to the application of DEA or B. bassiana alone for both larvae and adults. Larvae were more susceptible than adults in all treatments and exposure intervals. Insect survival and progeny production were recorded for four months. Significantly fewer progeny was noted on wheat treated with DEA + B. bassiana treatments compared with control. The maximum number of mycosed cadavers and the rate of sporulation were observed at the lowest dose of B. bassiana alone, followed by the higher doses gradually. These findings indicate that the DEA + B. bassiana combinations can efficiently control T. castaneum, providing long-term protection of wheat.

Assessment of Toxicity of Parthenium hysterophorus L. Extract against Larvae of Trogoderma granarium

et al. 2022

The leaves of parthenium (Parthenium hysterophorus L.) were extracted in ethanol and toxicity of the extract was examined on khapra beetle (Trogoderma granarium Everts) larvae. Four concentrations (2, 4, 6 and 8 µL mL-1 acetone) were applied directly on the larvae in Petri dishes. Toxicity was recorded after 12, 24 and 36 h. All the concentrations had considerable effect on the mortality of larvae. At the highest concentration (8 µL mL-1), the mortality observed was 57%, 72% and 78% after 12, 24 and 36 h, respectively. The minimum mortality was observed to be 43% at the concentration of 2 µL mL-1 acetone after 12 h. GC-MS analysis of the parthenium leaves showed 7 compounds in the extract including phytol (38.68%), β-cubebene (11.98%), hexadecanoic acid, methyl ester (11.22%), caryophyllene (10.37%), 9,12,15-octadecatrienoic acid, ethyl ester, (Z,Z,Z)- (9.98%), methyl stearate (9.01%), and hexadecanoic acid, ethyl ester (8.74%). The study concluded that an extract of 8 µL mL-1 acetone concentration is highly effective against larvae of khapra beetles that can cause 78% mortality after 36 h of direct exposure to the larvae.

“…In fact, T. granarium has been designated as an A2 quarantine pest and was named one of the 100 worst invasive species (Yadav and Srivastava, 2017). The larval stage is the most harmful, as it significantly reduces the value of stored grains (Ahmad et al, 2022;Honey et al, 2017;Shahbazi et al, 2022). The larvae consume the seed embryo before the entire kernel or seed, leaving behind only the husk; and it can significantly reduce the quality and quantity of stored goods and infests a wide range of raw grains and processed grain products.…”

Khapra beetle Trogoderma granarium is a destructive and voracious feeder of several stored products such as wheat, maize and rice, and it is a quarantine pest for wheat producing countries like Pakistan. The present study evaluated its biological and morphological parameters on different wheat varieties. The results revealed that its incubation period was varied from 7.01-8.91 days, being longest on the variety Faisalabad-08, and shortest on Sehar-06. Its total developmental period from egg-adult varied from 48.44- 64.16 days, respectively; male and female longevity was 19.14, and 17.02 days on Sehar-06. The weight of 6th instar larvae ranged from 6.21 to 7.11 mg, while the survival was maximum and minimum on Sehar-06 and Faisalabad-08, respectively. The minimum and maximum weight losses were observed in Faisalabad-08 and Sehar-06, respectively. Thus, Sehar-06 was observed to be the most susceptible variety giving maximum fertility and fecundity.
