“…The FAW is a polyphagous exotic and invasive pest which causes significant crop damage and threatening food and nutritional security [ 5 ]. The sole reliance on chemical control not only eliminated the natural defender population, but also, led to a slew of environmental issues such as pesticide residues, resistance to pesticides, pest resurgence, and effects on non-target organisms [ 31 ]. The current study focuses on potential biological and maize agroecosystem manipulation (intercropping different plants) interventions for S. frugiperda management in India.…”

“…In laboratory bioassays, moderate to high larval mortality was achieved with M. anisopliae , B. bassiana, Azadirachtin, Emamectin benzoate, and Chlorantraniliprole. Bio-pesticides are vital in IPM and are the best alternative to chemical control [ 31 ]. Azadirachtin was the most effective against the larvae among the biopesticides, followed by M. anisopliae and B. bassiana.…”

Spodoptera frugiperda (J.E. Smith) (Lepidoptera: Noctuidae) is an invasive pest native to the American continent. The present study focused on bio-intensive tactics like intercropping, using natural enemies, botanical insecticides and biopesticides for managing S. frugiperda for the organic production of maize in Indian conditions. A total of eight different parasitoids attacking the different stages of S. frugiperda viz., eggs and larvae were found in the study area. The total parasitism rate due to all the parasitoids ranged from 28.37 to 42.44%. The egg-larval parasitoid, Chelonus formosanus Sonan (Hymenoptera: Braconidae) was the dominant parasitoid (12.55%), followed by Chelonus nr. blackburni (Hymenoptera: Braconidae) (10.98%) and Coccygydium sp. (4.85%). About 36.58 percent of the egg masses collected was parasitized by egg parasitoids, among which Telenomus remus (Nixon) (Hymenoptera: Scelionidae) was the dominant parasitoid. The botanicals insecticides such as citronella and annona extract were most effective, resulting in 100% mortality of FAW larvae (168 h after treatment). The essential oil of garlic (100%) was found highly effective in inhibiting egg hatching, followed by geraniol (90.76%). The maize intercropped with lady’s finger (okra) recorded significantly the lowest pest infestation and recorded higher grain yield (6.17 q/ha) than other intercropping systems and control (5.10 q/ha). The overall bioefficacy of commercial biopesticides against the larvae of S. frugiperda was in the following order azadirachtin > Metarhizium anisopliae (Metch.) Sorokin (Hypocreales: Clavicipitaceae) > Beauveria bassiana (Balsamo) Vuillemin (Hypocreales: Clavicipitaceae) at 168 h after treatment.

Plant viral diseases are major constraints causing significant yield losses worldwide in agricultural and horticultural crops. The commonly used methods cannot eliminate viral load in infected plants. Many unconventional methods are presently being employed to prevent viral infection; however, every time, these methods are not found promising. As a result, it is critical to identify the most promising and sustainable management strategies for economically important plant viral diseases. The genetic makeup of 90 percent of viral diseases constitutes a single-stranded RNA; the most promising way for management of any RNA viruses is through use ribonucleases. The scope of involving beneficial microbial organisms in the integrated management of viral diseases is of the utmost importance and is highly imperative. This review highlights the importance of prokaryotic plant growth-promoting rhizobacteria/endophytic bacteria, actinomycetes, and fungal organisms, as well as their possible mechanisms for suppressing viral infection in plants via cross-protection, ISR, and the accumulation of defensive enzymes, phenolic compounds, lipopeptides, protease, and RNase activity against plant virus infection.

“…This situation demands for seeking some alternate environment-friendly pest control techniques for instance microbial, botanical, and non-conventional synthetic insecticidal formulations which are more biorational and are less toxic to non-target fauna (Arthurs and Dara, 2019;Rani et al, 2021;Acheuk et al, 2022;Ahmed et al, 2022). To this end, this study tested some selected biorational insecticidal formulations including botanical, microbial and differential chemistry non-conventional synthetic pesticides against 3 rd instar laboratory-reared S. litura first under the lab conditions and then the most effective treatments were further tested against 3 rd instar larvae either alone and/or in binary combinations in laboratory and under field conditions.…”

Armyworm species Spodoptera litura Fabricius (Lepidoptera: Noctuidae) is one of the destructive polyphagous insect pests worldwide and has attained field-evolved resistance to most of the conventional synthetic insecticides. In this study, some previously selected most effective biorational synthetic, botanical and microbial insecticidal formulations were evaluated either alone or in binary combinations against 3 rd instar larvae of S. litura under laboratory and then under the field conditions. In both trials, insecticidal treatments affected significantly the mean mortality or reduction of S. litura larvae recorded both at two and five days posttreatment. In laboratory bioassay, combinations of flubendiamide and A. indica, flubendiamide and N. tabacum and of spinetoram and A. indica formulations caused significantly high mortality (100%), followed by B. thuringensis and S. litura-NPV (94.92%) and A. indica and B. thuringensis (93.22%) and exhibited a synergized toxicity against S. litura larvae as compared to other treatments. In two years field trials, binary combination of flubendiamide and spinetoram showed an average larval reduction of 59 -100%, followed by 100% larval reduction exhibited by flubendiamide and spinetoram alone and by the combination of flubendiamide and A. indica formulations at 5 th day of application. While, minimum larval reduction was recorded for both microbial insecticides alone and in combination for both years. Overall results of this in-vitro and in-situ evaluation demonstrate the effectiveness of biorational insecticidal formulations and recommend their incorporation in integrated management of S. litura.Novelty Statement | Laboratory and then field evaluations of some promising botanical, microbial and non-conventional synthetic insecticidal formulations against 3 rd instar larvae of armyworm (Spodoptera litura) comprise the novelty of this study.
