“…Our experiment result shows that among all seven treatments spinosad 45 SC is found best effective for management of brinjal shoot and fruit borer following by indoxacarb 14.5 SC in both shoot and fruit infestation . The result of our study is in agreement with the findings of [21] who reported that mean infestation of shoot as well as fruit of L. orbonalis were recorded in brinjal plots treated by indoxacarb 14.5 SC 50 g a. i./ha (8.89 and 13.13%), followed by emamectin benzoate 5 SG 15 g a. i./ha (10.95 and 16.66%) [22,3,23,19,24,25]. Results are also in accordance with [26][27][28] which found spinosad is most effective treatment for the management of brinjal shoot and fruit borer.…”

Aims: This study aims to find out the most effective newer insecticides to control shoot and fruit borer in the brinjal. Study Design: The experiment of field was carried out with randomized block design. Place and Duration of Study: The field experiment on management of brinjal shoot and fruit borer Leucinodes orbonalis (Guen.) with newer insecticides were held on during October 2018 to April 2019 at Gwalior (Madhya Pradesh). Methodology: Infestation of shoot was observed from each plot by counting the total number of plants and the plants infested by shoot and fruit borer from the beginning of shoot formation. Total number of healthy fruits and infested fruits were counted from five plants of each plot at the time of fruit picking. The weight of both type of fruits (healthy and infested) were recorded to calculate the fruit infestation by weight basis. The treatments were applied from the initiation of infestation to till the complete harvest of the crop at 15 days interval regularly. The recorded data were subjected to statistical analysis after transformation. The count data also transformed and percentage were transformed to angular values. Results: The treatment of spinosad 45 SC and indoxacarb 14.5 SC1 (suspension concentrate) were found best among all treatments with 3.42 percent and 3.58 percent shoot infestation respectively and the treatments chlorantraniliprole 18.5 SC and flubendiamide 20 WG2 were found least effective with 4.69 percent and 4.78 percent infestation of shoot respectively. Treatments spinosad 45 SC and indoxacarb 14.5 SC were significantly reduced the 3.11 percent and 3.28 percent fruit infestation respectively. Whereas the treatments flubendiamide 20 WG (Water-Dispersible Granule) and chlorantraniliprole 18.5 SC were the least effective with 4.99 percent, 4.69 percent fruit infestation, respectively. Conclusion: Among all used treatments spinosad 45 SC and indoxacarb 18.5 SC, were the most effective treatments as they recorded higher yield and higher benefit cost ratio.

“…Azadirachtin interferes with egg laying, moulting, pupation, adult formation, respiration, and consumption [ 67 , 68 ]. Locally prepared neem botanicals have provided comparable control with synthetics for the lepidopteran pests Leucinodes orbonalis Guenee and Plutella xylostella L. in Nepal and West Africa [ 69 ]. Our result corroborates previous reports wherein neem gum nano-formulation, a novel biopesticide prepared from the neem gum extract, caused 100% antifeedant, larvicidal, and pupicidal activities against H .…”

Synthetic insecticides heavily applied to manage agricultural pests are highly hazardous to the environment and non-target organisms. Their overuse through repeated treatments in smallholder farming communities is frequent. Botanical biopesticides are ideal for sustainable pest management in agricultural environments by keeping synthetic insecticide use at a minimum. Here we evaluated a locally prepared neem seed extract (NSE) alongside emamectin benzoate against both lepidopteran pests Helicoverpa armigera (Hübner) and Spodoptera exigua (Hübner) on tomato Lycopersicon esculentum Mill under natural field conditions in Pakistan. We compared pest severity, fruit injury, quality, marketability, and cost:benefit ratio (CBR) between treatments. The concentration of azadirachtin A in the NSE was 26.5 ppm. NSE at 2% (20 mL/L) and the emamectin benzoate at the recommended field rate in Pakistan were sprayed weekly throughout the fruiting stage. The pest larvae were significantly more abundant on fruits than on flowers and leaves. Fruit injury and losses were significantly more important in untreated control compared to NSE and emamectin benzoate treatments. NSE efficacy varied with respect to the cultivars used and the seasons. Cultivar Eden harboured more pests than Adventa, and emamectin benzoate suppressed more pest individuals than NSE. Both the insecticidal treatments were comparable in terms of marketable yield productions as well as unmarketable, uninjured, and recovered fruit yields. NSE generated a higher CBR (1: 9.26) than emamectin benzoate (1: 3.23). NSE suppressed pests by acting as an antifeedant, similar to its synthetic counterpart. Smallholder growers can thus use NSE as a cost-effective solution in tomato pest management in Pakistan.
