Discussion Several governments give particular interest to the Trometamol Cancer agricultural economy, because it is one of the most important sources of national earnings. Therefore, there’s a great interest in agricultural pests along with the harm they bring about. Combating these pests has also turn out to be among the most important priorities of people. By way of example, preceding research happen to be concerned with controlling P. rapae; however, they did not resolve the problem. Additionally, most of these research focused on the use of chemical pesticides. Alternatively, studies on the biocontrol of P. algerinus stay scarce. As a result, the present study aimed to evaluate the efficacy of H. bacteriophora and S. riobravis, like their symbiotic bacteria Photorhabdus sp. and Xenorhabdus sp., respectively, against P. rapae and P. algerinus larvae. The outcomes revealed that both H. bacteriophora and S. riobravis nematodes effectively induced mortality in P. rapae and P. algerinus larvae. These outcomes were in accordance with those of Ali et al. [30], who reported the efficacy of Steinernema masoodi, Steinernema seemae, Steinernema carpocapsae, Steinernema glaseri, and Steinernema thermophilum against Helicoverpa armigera, G. mellonella, and Corcyra cephalonica. Moreover, Reda et al. [16] reported that S. carpocapsae induced mortality in fourth-instar larvae and the pupae of P. rapae, with LC50 values of 18.148 and 38.96 IJs/larva and pupa, respectively. Recently, Askary and Ahmad [31] also recorded the efficacy of Heterorhabditis pakistanensis for controlling Pieris brassicae. Likewise, Grewal et al. [32] and Kleim et al. [33] improved the susceptibility of Japanese beetle, Popillia japonica, to EPNs infecting turf within the USA. WU [34] also reported the efficacy of H. bacteriophora and H. megidis against masked chafer white grubs, Cyclocephala spp. Similarly, Kajuga et al. [35] reported that both H. bacteriophora and S. carpocapsae killed as much as 58 of white grubs. Yet another study also reported that Steinernema abbasi and Heterorhabditis indica had the capability to handle the white grub Leucopholis lepidophora [36]. The obtained information also revealed that H. bacteriophora was far more productive than S. riobravis against both P. rapae and P. algerinus. Shapiro-Ilan et al. [37,38] attributed the discrepancy within the infectivity and virulence of distinctive EPN strains to diverse foraging behavior, host specificity, morphological characterization with the ENs, and also the tolerance to host immune defenses. Based on foraging behavior, EPNs have already been classified into cruisers (active searchers) and ambushers (sit-and-wait foragers) [39]. Earlier studies classified Heterorhabditids as cruisers and Steinernematids as ambushers [39]. Therefore, the superiority of H. bacteriophora more than S. riobravis in this study can be attributed to its foraging behavior as a cruiser. Grewal et al. [40] attributed the greater impact of H. bacteriop.
