“…Breaking the insecticide resistance epidemic was an urgent necessity in China, where 46% of the world's brassica crops are produced (FAO 2019). An added bonus was the extremely high activity of FLB against P. xylostella (Ebbinghaus-Kintscher et al 2007;Troczka et al 2017). FLB was first launched in the Philippines in 2006 and subsequently in Thailand in May 2007.…”

Diamide insecticides selectively acting on insect ryanodine receptors (RyR) were launched to the market more than 10 years ago, particularly targeted for the control of lepidopteran pest species in diverse agronomic and horticultural cropping systems. They are now globally registered in many countries and provide reliable control levels in most settings. However, their frequent application, due to alternative mode of action chemistries often not providing sufficient levels of control, has resulted in the selection of diamide resistance in some of the world's most destructive lepidopteran species, including populations of diamondback moth, tomato leafminer, rice stem borer and more recently beet armyworm. High levels of diamide resistance, compromising diamide efficacy at recommended field rates, has been shown to be conferred by RyR target-site mutations affecting diamide binding. The present work reviews the global status of diamide insecticide resistance in lepidopteran pests, with special reference to RyR target-site alterations. Furthermore, we discuss principles enabling the prediction of the impact and spread of diamide resistance, based on population genetics and associated fitness costs as influenced by the known target-site mutations recently described. In this context, we reiterate calls by the Insecticide Resistance Action Committee to implement effective diamide insecticide resistance management by following a three-step strategy of resistance identification, tracking and prediction according to the protocols discussed in this article. Key message• Diamide insecticide resistance has reached levels compromising the control of some of the most destructive lepidopteran pest species at recommended field rates. • The major mechanisms of resistance are reviewed, with particular reference to ryanodine receptor target-site mutations affecting diamide binding. • A refined Lepidoptera ryanodine receptor homology model helps to further delimit the putative diamide binding site. • Resistance management tactics based on identifying, tracking and predicting diamide resistance are considered key to conserve their efficacy.Communicated by N.

“…Larvae damage occurs by tunnelling in the foliage and feeding on the leaves of plants such as cabbage, kale, swede, turnip and brussels sprouts (Talekar & Shelton, ; Zalucki et al ., ). DBM is the most problematic pest to control in cruciferous vegetables because it has developed resistance to 93 insecticides from different chemical classes (Troczka et al ., ). Only a few species of Ichneumonid and Braconid parasitoids such as Diadegma sp.…”

1 The life-history parameters and predation capacity of Macrolophus pygmaeus Rambur and Nesidiocoris tenuis (Reuter) (Hemiptera: Miridae) fed on eggs of Plutella xylostella (L.) (Lepidoptera: Plutellidae) at 25 ∘ C were investigated in the laboratory and analyzed based on the age-stage, two-sex life table. Also, we evaluated the survival and the duration of different stages of these two predators on cabbage plants without prey. 2 The developmental times of different stages of M. pygmaeus and N. tenuis fed on the eggs of P. xylostella were significantly different. The nymphs of N. tenuis only survived until the fourth instar without prey, and nymphs of M. pygmaeus succeeded in completing the third instar without prey. 3 The population and predation parameters of the two predators were statistically different. The total consumption rate of the two predators during the oviposition period was higher than the total consumption rate during the post oviposition period and the total preoviposition period. 4 The highest predation rates for female adults of N. tenuis and M. pygmaeus were on days 33 and 31, respectively. 5 The nymphs of N. tenuis only survived until the fourth instar without prey, and nymphs of M. pygmaeus succeeded in completing the third instar.

“…It damages cruciferous crops, such as cabbage and radish, and generally produces 9 to 12 generations annually in subtropical countries (Talekar & Shelton 1993); the annual cost of management is estimated to be greater than $1 billion U.S. (Sayyed et al 2002). Resistance has been observed to chlorantraniliprole and flubendiamide as well as to diamide, a relatively new insecticide (Guo et al 2014;Kang et al 2017;Troczka et al 2017).

“…Many insecticides have low efficacy against P. xylostella because it exhibits high crossresistance and multiple resistance to most insecticides (Mohan & Gujar 2002).

Insecticidal and antifeeding activities against Plutella xylostella were observed using whole‐plant‐derived Perilla frutescens material. The active ingredient in P. frutescens was identified by spectroscopic analysis as the sesquiterpenoid α‐farnesene, which showed insecticidal activity against third‐instar larva of P. xylostella in a leaf‐dipping bioassay based on 24‐h LD50 values (LD50 = 53.7 ppm). The feeding inhibition rate of α‐farnesene was 82.98% against P. xylostella at 10 ppm, and the antifeeding responses were determined using an oscilloscope to detect electrophysiological responses. The electrophysiological responses of the medial styloconic sensillum (MSS) were approximately 7‐fold more sensitive at 100 ppm than those of the lateral styloconic sensillum (LSS). These results suggest that the insecticidal and antifeeding effect of α‐farnesene, which is a P. frutescens‐derived material, can be used as a potential control agent for P. xylostella.
