“…Several beneficials, including Nesidiocoris tenuis (Reuter, 1895) (Hemiptera: Miridae), were observed in tomato fields (Garba et al, 2020; Sawadogo et al, 2020b). N. tenuis preferred preys include whiteflies, aphids, thrips and moths, among which important pests like Spodoptera exigua Hubner (Lepidoptera: Noctuidae) and T. absoluta (Calvo et al, 2009; Gavkare & Sharma, 2019; Urbaneja et al, 2008; Yano et al, 2019). Unlike other members of its family, this zoophytophagous species can hardly survive on tomato in the absence of prey (Molla et al, 2014).…”

Tuta absoluta (Lepidoptera: Gelechiidae) is a worldwide invasive insect species, considered a major pest of tomato. It has recently established in Burkina Faso, where chemical control remains the only affordable option to limit damages. Nesidiocoris tenuis (Hemiptera: Miridae) is commercialized as a biological agent to control this pest in other parts of the world. But very limited information exists on this predator in Burkina Faso. In this study, we first performed an insect survey in all agricultural regions areas of the country, and we found N. tenuis to be widely observed in all of them. Then, we performed two laboratory bioassays and demonstrated that all instars preyed on T. absoluta eggs, whether they were fed ad libitum or they had to actively forage for their prey. Because insecticide tolerant populations of T. absoluta were recently identified, we finally aimed at identifying agrochemicals that do not harm N. tenuis. We evaluated the toxicity of two synthetic insecticides, three bio‐bacterial insecticides and eight plant extracts, all being active ingredients available on the local market. Most of them (i.e., abamectin, emamectin benzoate, spinosad, spinetoram) were highly toxic for both T. absoluta and N. tenuis. In contrast, Bacillus thuringiensis var. Kurstaki, neem oil, Cleome viscosa (Asian spiderflower), Ocimum basilicum (Basil) and Cassia occidentalis (Coffee senna) were compatible with N. tenuis while still controlling T. absoluta. Based on our results, we recommend the application of Bacillus thuringiensis to both control T. absoluta and which does not compromise the maintenance of N. tenuis populations.

“…Global warming is occurring, and climate change is likely to have a signi cant impact on human energy and insect species. Temperature is the most essential element directly impacting insect development, survival, distribution, and abundance among climatic variables (Zhang et al, 2008;Ju et al, 2011;Gavkare and Sharma, 2017). As a result, it's critical to comprehend the le's temperature effect on the census.…”

Background Entomopathogenic nematodes (EPNs) are a type of biological control agent that has been extensively studied. Under field and laboratory settings, the efficiency of two EPNs species, Heterorhabditis indica and Steinernema feltiae, isolated locally from soils of Rajghar, Himachal Pradesh, India, against an important invasive pest, Tuta absoluta (Meyrick) (Lepidoptera: Gelechiidae), was assessed. Results Steinernema feltiae (isolate- HR-1) and Heterorhabditis indica (isolate- HA-2) species dose (10, 20, 40, 80, 160 IJs/cm2) are used in the lab bioassay. The third instar (percentage) ranges from 24.15 to 90.00 percent. HR1 and HA2 isolates demonstrated significant larvicidal activity with LC50, LC75, and LC90 of all instars and pupa show high mortality from 31.53 to 90.00 percent and 72-hours exposure duration. The strain slows larval development in 48 to 72 hours of exposure period, with LC50 values ranging from 05.42 to 19.29, LC75 values ranging from 20.29 to 83.12, and LC90 values ranging from 26.03 to 78.89. Greenhouse test seam isolates are foliar sprayed three times at a 14-day interval, with total findings revealing a 7.36 ore count range before spraying. The total treatment outcomes range from 1.64 to 1.74 for isolate HA-2, and 1.88 and 2.03 for HR-1. 4.15 percent was recorded in the control plot. Conclusion Invasive species pose a significant threat, as evidenced by this research. Traditional EPNs (S. feltiae HR-1, H. indica HA-2) have been used as an active biocontrol agent in laboratory and greenhouse settings, as well as the pathogen that infects T. absoluta.

“…In the absence of effective control methods, it might cause complete plant destruction. This insect mostly feeds on tomato leaves, fruits, shoots, and apical T. absoluta, a South American tomato leafminer, was discovered in Himachal Pradesh in 2015 in Nauni, Solan (Gavkare and Sharma, 2017). The control of this insect has become a major concern for tomatoes grown in open elds and polyhouses across the state.…”

“…The acquired data suggested that the nal instar of larval insects was more susceptible than the previous larval instars, as well as those exposed to the tested EPN doses.Log probit analysis of larvicidal activityTo determine the lethal concentration of entomopathogenic nematodes to the nal larvae of S. frugiperda, a toxicity assay was performed. The LD 50 and LD 90 for S. feltiae and H. bacteriophora(10,20,40, 80, 160 IJs/cm 2 ) doses, nal instar for 72 h were evaluated as 24.66 IJs/cm 2 , 10.85 IJs/cm 2 and 67.17 IJs/cm 2 , 61.69 IJs/cm 2 respectively, utilizing (OPSTAT) software, the best larvicidal activity was obtained to compare other strains, the H. bacteriophora and S. feltiae strains demonstrated robust larvicidal activity at low concentrations even after 48 and 72 hours of exposure (Table1) (Figs.8 & 9).…”

The agro-climatic zones survey was conducted diversity and frequency of endemic entomopathogenic nematodes (EPNs) in Apple orchards in Rajgarh, western Himalayas. Isolated EPNs have been used as an active biocontrol agent against T. absoluta and S. frugiperda. The total survey of 42 locations apple orchards were collected from which 281 soil samples and tested 7 soil samples are positive for the presence of EPN. Native isolated strains morphologically and molecular identification of nematodes, insect and bacterial sequencing and characterisation of the internal transcribed spacer (ITS) 18S, 12S and 16S region was used to identify all nematode isolates, insects and bacterial strains upto species level (S. feltiae UHF-HR1, H. bacteriophora UHF-HR2; T. absoluta SN1, S. frugiperda SN2; X. bovienii R1, P. luminenscens R2). There have been used as an active biocontrol agent against T. absoluta and S. frugiperda. The bioassay of after 72 hours with different concentrations of 10, 20, 40, 80, and 160 IJs/cm2, the data susceptibility of T. absoluta 4th larval and S. frugiperda 5th instar to infection with the nematode S. feltiae and H. bacteriophora mortality range 74.12 to 90.00 percentage mortalities. To assess the lethal concentration of entomopathogenic nematodes to insect larvae, a toxicity evaluation the LD50 and LD90 for S. feltiae and H. bacteriophora doses in final instar the best larvicidal activity was obtained during the 72-hour exposure period, The susceptibility of infection was found to be greater than 80%. The strains R1 and R2 bacterial isolates were bioassay experiments were X. bovienii and P. luminescens of treatment throughout the investigation, daily larval mortality ranged from 0.00 to 90.00 percent. Our analysis confirmed the steep inclination of S. frugiperda and T. absoluta. S. feltiae UHF-HR1 and H. bacteriophora UHF-HR2 & Photorhabdus and Xenorhabdus were utilised, with 90 percent control over both entomopathogenic nematodes and their symbiotic bacterial strains.
