“…The emergence of insecticide resistant populations has driven current research towards the development of alternative methods for control of this pest and particularly natural pest control ( Tabashnik and Cushing , 1987). This paper focuses on the status of P. xylostella and its natural enemies in Brasilia where cabbages are a major food crop and insecticides are inefficient for control ( Castelo‐Branco and Gatehouse , 1997).…”

The diamond back moth Plutella xylostella (L.) is the most serious pest of Brassicaceae in the world. It is resistant to many insecticides which has led to a search for alternative techniques of control, principally biocontrol‐based pest management. The impact of P. xylostella and its parasitoids was analysed in a 6‐month study of cabbage crops in the Brasilia region of Brazil, from June to November 1998. The population of the pest and its guild of parasitoids were quantified on two experimental plots at the Embrapa‐Hortaliças research station by weekly samplings. In the first cropping (June to early September), populations of P. xylostella followed a logistic growth curve leading to the destruction of the crops. In the second cropping, rains prevented the development of P. xylostella. Seven species of parasitoids were observed, Diadegma leontiniae (Brethes) and Apanteles piceotrichosus (Blanchard) being dominant. Cotesia plutellae (Kurdjumov) and Actia sp., previously more abundant, became very minor parasitoids. Significant differences were observed in specific parasitism rates between the plots. The combined parasitism rates were identical on both plots (around 23%) and were insufficient to regulate the populations of P. xylostella. Six species of hyperparasites were reared from Diadegma leontiniae and Apanteles piceotrichosus, showing a high diversity of natural enemies in this region of recent colonization by P. xylostella.

“…The diamondback moth, Plutella xylostella (L.) (Lepidoptera: Plutellidae), is the most destructive pest of cruciferous crops worldwide because of its high fecundity, short life cycle, and high genetic plasticity (Castelo, Branco & Gatehouse, ; Jiang, Wu, Yang, Zhu, & Gao, ; Oliveira, Siqueira, Silva, Oliveira, & Michereff, ; Santos, Siqueira, Silva, & Farias, ). Annually, the total cost of management and incurred crop losses due to this pest exceed 0.77 billion USD in China and 4–5 billion USD throughout the world (Furlong, Wright, & Dosdall, ; Li, Feng, Liu, You, & Frulong, ).…”

The diamondback moth, Plutella xylostella (L.) (Lepidoptera: Plutellidae), is a widespread and destructive pest of cruciferous crops. New strategies for controlling it are needed because it is rapidly developing resistance to conventional pesticides. In insects, transcription factors (TFs) including broad-complex (Br-C) are thought to be useful for insecticide development because they are able to regulate the transcription of functional genes involved in responses to external stimuli including insecticides. In the present study, we cloned and sequenced the open reading frames (ORFs) of three BTB-ZF encoding genes from the diamondback moth deposited in the National Center for Biotechnology Information (NCBI) database under accessions MG753773, MG288674, and MG753772. The lengths of these ORFs were 1,680, 1,428, and 1,647 bp, respectively. The phylogenetic analysis based on the predicted amino acid sequences of ZF domains showed that MG753773 and MG288674 belonged to Z2/Z3 and Z7 of Br-C while MG753772 belonged to Ttk types. In the agreement, the highest expression level of MG753773 occurred during the Arch. Insect Biochem. Physiol. 2019;101:e21549.wileyonlinelibrary.com/journal/arch

“…However, P. xylostella has developed resistance to many synthetic insecticides because of its high fertility, tendency towards overlapping generations, genetic plasticity, and, in particular, selection pressure from the use of various insecticides. The application of pesticides, in some years has, nevertheless, been shown to be ineffective in the control of P. xylostella , even after 15 to 20 applications during a crop cycle [ 5 , 6 , 7 ]. Pesticide use is particularly common due to its practicality, speed, and efficiency in population control [ 4 ]; however, its use can select more resistant individuals [ 8 ], thereby exacerbating the problem.…”

“…These insecticides can be prepared from locally available plants [ 8 ], have an advantageous cost/benefit ratio [ 12 ], and have low toxicity [ 10 , 13 , 14 ]. Several plant species have been examined to evaluate their insecticidal effect, since they may offer higher selectivity [ 6 , 7 ], lower toxicity to non-target organisms [ 4 ], local availability, low resistance, and low cross-resistance due to their natural complexes [ 12 , 13 ]. Studies conducted by Amoabeng et al [ 12 ], which assessed the cost/benefit ratio of using plants to control insects, have revealed that botanical insecticides might differ in the level of pest control and beneficial cost when compared with conventional insecticides.…”

Successive applications of insecticides to control Plutella xylostella L. (Lepidoptera: Plutellidae) have resulted in the emergence of resistant populations of this insect. A novel control measure for this target insect could be the use of botanical insecticides derived from plant tissues. Hence, we experimentally tested aqueous extracts of Alibertia edulis (Rich.), Alibertia intermedia (Mart.), and Alibertia sessilis (Vell.) K. Schum. found in the Brazilian savannah in order to investigate their potential to disrupt the life cycle of P. xylostella. Aqueous extracts of the leaves of A. intermedia and A. sessilis negatively affected the development of P. xylostella in all stages of the life cycle, prolonging the larval stage and causing mortality in the larval or pupal stages. Treatments with A. intermedia and A. sessilis extracts caused the lowest fecundity and the number of hatched larvae. The harmful effects of these aqueous extracts on the life cycle of P. xylostella may be attributable to the flavonoids and other phenolic compounds present in A. intermedia and A. sessilis. These aqueous botanical extracts are low in toxicity when compared to non-aqueous pesticides, and may emerge as an effective approach for control of populations of P. xylostella.
