“…Functionalization of MCM-41 was performed by the hydroxyl group of entomopathogenic fungus. Some studies have revealed the efficacy of L. lecanii in pest control (Ghaffari et al, 2017;Alavo, 2015;Schreiter et al, 1994;Ramanujam et al, 2017). Our findings confirm L. lecanii pathogenicity against adults of B. brassicae so it will be an efficient candidate for integrated B. brassicae management strategies.…”

Brevicoryne brassicae is a significant pest of cultivated cabbages and vegetable crops in the world. The present study was carried out to examine a potential strategy to enhance the insecticidal activity of Lecanicillium lecanii for cost-effective management of B. brassicae. The insecticidal efficacy of pure entomopathogenic fungus (PEF) and MCM-41 (Mobil Composition of Matter) L. lecanii were assessed against the cabbage aphid under laboratory and greenhouse conditions. The fungus was supported on MCM-41 and was completely characterized by Scanning Electron Microscope (SEM), thermogravimetric analysis (TGA) and Fourier transform infrared (FT-IR) techniques. LC50 values of PEF and MCM-41@fungus were 1.9×106 and 2.5×104 and 2.0×107 and 2.0×105 conidia/ml on adults of B. brassicae under laboratory and greenhouse conditions, respectively. Bioassays demonstrated that MCM-41@fungus significantly decreased LC50 values of entomopathogenic fungus and it was more toxic than L. lecanii at adult stage of the pest. The results showed that pure L. lecanii and its nano-formulation could play key roles as bio-pesticides in B. brassicae management programs.

“…And the entomopathogenic fungal species described and commercialized, L. lecanii (Zare & Gams, 2001) deserves further consideration as a broad range commercial biopesticide, due to its wide range of hosts and wide geographical distribution (Xie et al, 2015). Indeed, this species can infect the diamondback moth Plutella xylostella (L.) (Lepidoptera: Plutellidae) (Ravindran et al, 2018), aphids (Hemiptera: Aphididae) (Askary, Benhamou & Brodeur, 1999), the citrus mealybug Planococcus citri Risso (Hemiptera: Pseudococcidae) (Ghaffari et al, 2017), and the soybean cyst nematode Heterodera glycines Ichinohe (Tylenchida: Heteroceridae) (Shinya et al, 2008), and has also been documented to infect Bemisia tabaci (Zhu & Kim, 2011). In insects, the spores of entomopathogenic fungi germinate, and the fungal hyphae penetrate the epidermis and invade the tissues and organs until reaching the hemocoel (Duan et al, 2017).…”

Background Lecanicillium lecanii is an entomopathogenic fungi, which was isolated from insects suffering from disease. Now, it is an effective bio-control resource that can control agricultural pests such as whitefly and aphids. There are many studies on the control of various agricultural pests by L. lecanii, but no report on its control of Bemisia tabaci biotype-Q exists. In this work, we studied the susceptibility of B. tabaci Q-biotype (from Ningxia, China) to L. lecanii JMC-01 in terms of nymph mortality and the changes in detoxifying protective enzymes activities. Methods B. tabaci nymphs were exposed to L. lecanii JMC-01 conidia by immersion with the host culture. Mortality was assessed daily for all nymph stages. The detoxifying and protective enzyme activity changes, weight changes, and fat, and water contents of the nymphs were determined spectrophotometrically. Results All instars of B. tabaci died after being infested with 1 × 108 conidia/mL. The 2nd-instar nymphs were the most susceptible, followed by the 3rd-instar nymphs. The corrected cumulative mortality of the 2nd- and 3rd-instar nymphs was 82.22% and 75.55%, respectively. The levels of detoxifying and protective enzymes initially increased and then decreased. The highest activities of carboxylesterase, acetylcholinesterase, peroxidase, and catalase occurred on the 3rd day, reaching 10.5, 0.32, 20, and 6.3 U/mg prot, respectively. These levels were 2.2-, 4.3-, 2.4-, and 1.4-fold the control levels, respectively. The highest activities of glutathione-S transferase and superoxide dismutase on the 2nd day were, respectively, 64 and 43.5 U/mg prot. These levels were, respectively, 2.7 and 1.1-fold that of the control level. The water and fat content in the infected B. tabaci nymphs decreased and differed significantly from the control levels. The weight increased continuously in the first 24 h, decreasing thereafter. At 72 h, the infestation level was about 0.78-fold that of the control level. Conclusions The studied L. lecanii JMC-01 strain is pathogenic to the B. tabaci Q-biotype. This strain interferes with the normal functioning of detoxifying and protective enzymes, and is also involved in the disruption of normal physiological metabolism in B. tabaci.

“…near pseudococci (Mansour et al 2011b). Microbial biopesticides composed of entomopathogenic fungi (Lecanicillium longisporum (Petch) or Lecanicillium lecanii (Zimmere)) are potentially useful biological control agents for citrus mealybug (Ghaffari et al 2017). (c) Optimized insecticide application timing: to improve scouting and spray timing, grape growers could consider the fact that vine mealybug populations are more exposed on the grapevine at certain periods of the year (Wilson and Daane 2017).…”

Synthetic chemicals are extensively used to limit the substantial crop damage induced by two closely related scale insects, the vine mealybug Planococcus ficus (Signoret) and the citrus mealybug Planococcus citri Risso (Hemiptera: Pseudococcidae). Both organisms are economically important pests occurring in vineyards and/or in citrus orchards worldwide. Synthetic chemicals can be either incorporated in pesticides aimed at directly controlling these pests or used as semiochemicals (i.e., sex pheromones) for monitoring, mass trapping, mating disruption, and/or for kairomonal attraction to enhance parasitoid performances. Growing evidence of both an alarming bee decline and destruction of auxiliary fauna driven by pesticides have stimulated an urgent need for in-depth research clarifying the adverse side effects of pesticides on beneficial arthropods. We have reviewed the current knowledge on mealybug pest control based on insecticides and semiochemicals. We highlight the following major advances: (1) How the active substances of insecticides (four organophosphates, imidacloprid, buprofezin, and spirotetramat) affect target and non-target organisms, (2) in which contexts and how a semiochemical-based strategy could be applied to deal with serious mealybug infestations, and (3) the implications of the appropriate exploitation of these synthetic chemicals for sustainable development. Using selective insecticides with novel modes of action and long-lasting efficacy in combination with eco-friendly semiochemical-based tools is a promising strategy for developing sustainable integrated pest management programs. This would help to maintain biodiversity dynamics and vital ecosystem services, thereby sustaining crop yields.
