Aenasius bambawalei Hayat (Hymenoptera: Encyrtidae) is a solitary nymphal endoparasitoid of mealybug, Phenacoccus solenopsis Tinsley (Hemiptera: Pseudococcidae). The parasitism performance of A. bambawalei on the 3rd nymphal instar of P. solenopsis at different densities 20, 30, 40 and 50 P. solenopsis was tested. The results showed that the maximum number of P. solenopsis parasitized and male and female adults emerged at 30 P. solenopsis density than other densities. Similarly, the maximum sex ratio M: F (1: 1.7) was found at 50 P. solenopsis density as compared to others. The highest parasitization percentage was observed on 3-day old A. bambawalei at all P. solenopsis densities. The 30 P. solenopsis density is the most preferred and suitable for mass rearing of A. bambawalei and the 3-day old parasitoid use of biological control programme to control P. solenopsis.

“…A temperatura está entre os mais importantes fatores que regulam o desenvolvimento e a reprodução dos insetos (JU et al 2011), sendo organismos pecilotérmicos, o desenvolvimento, reprodução e o potencial predatório dos insetos é afetado em grande parte por variações de temperatura no ambiente. Os insetos funcionam melhor apenas em uma determinada faixa de temperatura (RANA, 2006;IFTIKHAR et al 2018). Nesse sentido o aprendizado sobre o efeito de tal fator é essencial para melhorar os métodos de criação, prever o estabelecimento de campo e atividade de espécies insetos predadores que são etapas centrais em programas de controle biológico (FERREIRA et al 2020).…”

“…For decades, chemicals served as the primary source in insect pest management; however, insects can develop high resistance to synthetic chemicals by coating their body with waxy secretion to protect them from outside harm and prevent it from penetrating their bodies (Ghaffari et al, 2017;Cocco et al, 2020). Furthermore, the extensive use of chemicals as pesticides negatively impacts other beneficial insects and affects the ecosystem balance (Iftikhar et al, 2018). For those reasons, researchers have been focusing on developing eco-friendly management approaches because of the adverse effects of synthetic chemicals on human health and the environment (Shankarganesh et al, 2022;Pathak et al, 2022).…”

Planococcus citri is a common insect pest that poses a serious threat to citrus crops. Treatment of Planococcus citri with chemical pesticides causes harm to humans, animals, and the environment. This study aimed to use silver nanoparticles as potential alternatives to control this agricultural insect pest. Silver nanoparticles (AgNPs) have been identified using X-ray diffraction (XRD), ultraviolet-visible (UV-Vis) spectroscopy, and scanning electron microscopy (SEM). An absorbance peak at 425 nm in the UV-Vis spectrum showed the existence of AgNPs due to plasmon resonance. XRD patterns verified that the AgNPs possess a highly crystalline structure. SEM imaging showed that the AgNPs were spherical in shape with an average size of 12.4 nm. Toxicological tests of the prepared silver nanoparticles showed they are effective in insecticidal activities in different stages of the mealybug. Using the synthesized silver nanoparticles for more than 72 hours of treatment at a concentration of 100 ppm resulted in the highest killing rates of 40.0, 68.0, and 70.0% for the development of three stages of the mealybug, including eggs, the first age of nymphs, and adult females, respectively. The lowest percentage of the insecticidal efficacy of silver nanoparticles was recorded at a concentration of 5 ppm, reaching 62.75 and 4.6 % after 3 and 7 days, respectively. To our knowledge, it is noteworthy to report that nanoparticles were successfully synthesized from the extract of Pelargonium citronellum for the first time. The results have demonstrated the potential of natural extracts as a source of nanoparticles to manage mealybugs.
