“…The contradictory observation with Ca 2+ is its ability to stimulate ATP synthesis and mitochondrial dysfunction as a result of loss of cellular Ca 2+ homeostasis (O‐Uchi et al., ). Flubendiamide also has larvicidal action as a stomach poison and an oral intoxicant (Takkar, Sahoo, Singh, Battu, & Singh, ). Insecticides interfering with mitochondrial respiration induce generation of ROS such as free radicals (FR), hydrogen peroxides (H 2 O 2 ) and peroxynitrite anions which interact with the cellular organic matters such as membranes, lipids and proteins, and nucleic acids leading to the oxidative damage.…”

Phthalic acid diamide insecticides are the most effective insecticides used against most of the lepidopteran pests including Helicoverpa armigera, a polyphagous pest posing threat to several crops worldwide. The present studies were undertaken to understand different target sites and their interaction with insect ryanodine receptors (RyR). Bioassays indicated that flubendiamide inhibited the larval growth in dose-dependent manner with LD value of 0.72 μM, and at 0.8 μM larval growth decreased by about 88%. Flubendiamide accelerated the Ca -ATPase activity in dose-dependent trend, and at 0.8 μM, the activity was increased by 77.47%. Flubendiamide impedes mitochondrial function by interfering with complex I and F F -ATPase activity, and at 0.8 μM the inhibition was found to be about 92% and 50%, respectively. In vitro incubation of larval mitochondria with flubendiamide induced the efflux of cytochrome c, indicating the mitochondrial toxicity of the insecticide. Flubendiamide inhibited lactate dehydrogenase and the accumulation of H O , thereby preventing the cells from lipid peroxidation compared to control larvae. At 0.8 μM the LDH, H O content and lipid peroxidation was inhibited by 98.44, 70.81, and 70.81%, respectively. Cytochrome P450, general esterases, AChE, and antioxidant enzymes (catalase and superoxide dismutase) exhibited a dose-dependent increasing trend, whereas alkaline phosphatase and the midgut proteases, except amino peptidase, exhibited dose-dependent inhibition in insecticide-fed larvae. The results suggest that flubendiamide induced the harmful effects on the growth and development of H. armigera larvae by inducing mitochondrial dysfunction and inhibition of midgut proteases, along with its interaction with RyR.

“…Takkaret al (2011) [13] also reported the residues of flubendiamide 480 SC on brinjal fruits at 90 and 180 g a.i.ha -1 and observed that the initial deposit of 0.33 and 0.61 mg kg -1 , dissipated by 76.00 and 79.00 per cent after 3 rd day of application and half life ranged from 0.62 days and 0.54 days, at single and double doses, respectively.…”

Studies were undertaken to establish dissipation dynamics of commonly used insecticide at recommended dose both in open field and poly house situations to assess the differences in rate of dissipation, and also to recommend Pre-Harvest Intervals based on MRLs established by CAC and FSSAI. Utilizing flubendiamide 20% WG @ 48 g a.i. ha-1sprayed at three times and capsicum samples collected at regular intervals were analysed for residues.. The dissipation pattern of insecticides varied in poly houses and open fields, where initial deposits were comparatively higher and dissipated slowly in poly houses, Spray of flubendiamide at recommended dose resulted in 2.40 mg kg-1 initial deposit at 2 hours after spray which dissipated to BDL by 10th day in poly house. However, as the Codex MRL is 2 mg kg-1, a PHI of 1 day is ideal for food safety. Whereas in open field, 2.13 mg kg-1initial deposit at 2 hours after spray which dissipated to BDL by 10th day in open field.

“…Mohapatra et al (2010) reported 3.9 and 4.45-day half-life values of flubendiamide on cabbage following application of flubendiamide at 24 and 48 g a.i.ha −1 . The half-life values of flubendiamide on brinjal were observed to be 0.62 and 0.54 days, respectively, following three applications of flubendiamide 480 SC at 90 and 180 g a.i.ha −1 on brinjal fruits (Takkar et al 2012). Similarly, the half-lives of flubendiamide were reported to be 2.68 and 2.55 days following application of flubendiamide at 90 and 180 g a.i.ha −1 on brinjal fruits (Chawla et al 2011).…”

“…As with the other insecticides, the residues of flubendiamide on tomato declined with time, and a fairly high rate of dissipation was observed. These Takkar et al (2012) who studied the residues of flubendiamide and desiodo flubendiamide following three applications at 90 and 180 g a.i. ha −1 on brinjal fruits and reported an average initial deposit of 0.33 and 0.61 mg kg −1 , respectively, at single and double dosages.…”

Supervised field trials were conducted at four different agro-climatic zones in India to evaluate the dissipation pattern and risk assessment of flubendiamide on tomato. Flubendiamide 480 SC was sprayed on tomato at 48 and 96 g active ingredient (a.i.) ha(-1). Samples of tomato fruits were drawn at 0, 1, 3, 5, 7, 10, 15, and 20 days after treatment. Quantification of residues was done on a high-performance liquid chromatography (HPLC) device with a photo diode array detector. The limit of quantification (LOQ) of this method was found to be 0.01 mg kg(-1) while limit of detection (LOD) being 0.003 mg kg(-1). Residues of flubendiamide were found below the determination limit of 0.01 mg kg(-1) in 20 days at both the dosages in all the locations. The half-life of flubendiamide at an application rate of 48 g a.i. ha(-1) varied from 0.33 to 3.28 days and at 48-g a.i. ranged from 1.21 to 3.00 days. On the basis of data generated under the All India Network Project on Pesticide Residues, a preharvest interval (PHI) of 1 day has been recommended, and the flubendiamide 480 SC has been registered for its use on tomato by the Central Insecticide Board and Registration Committee, Ministry of Agriculture, Government of India. The maximum residue limit (MRL) of flubendiamide on tomato has been fixed by the Ministry of Health and Family Welfare, Government of India under Food Safety Standard Authority of India, as 0.07 μg g(-1) after its risk assessment.
