“…Previous studies (Vincent et al, 2000) described the negative effect of imidacloprid, especially on ladybirds, such as larvae and adults of Harmonia axyridis (Pallas). Santos et al (2017) and Schiess et al (2017), verified its high toxicity for Hippodamia convergens (Guérin-Méneville), a coccinellid abundant on the plants in our study. As the populations of M. donacis did not affect yield and imidacloprid is toxic to the beneficial fauna (Mizell and Sconyers, 1992), its application is not advisable for the management of this aphid, and natural control should be considered.…”

Giant reed, Arundo donax (L.), is known for its potential as a bioenergy crop. To evaluate the effect of the aphid Melanaphis donacis (Passerini) on plants growing in the Metropolitan Region of Chile, three treatments with six plots each were compared: imidacloprid, the agricultural detergent TS2035, and an untreated control. Aphid density levels in the untreated control plants averaged 136.27 aphids leaf-1 along the growing season, while TS2035 and imidacloprid averaged 8.26 and 0.98 aphids leaf-1 , respectively. The greatest yield of A. donax (95.1 t dry matter (DM) ha-1) was obtained with the TS2035 detergent, followed by imidacloprid and the untreated control, with values of 88.8 and 84.1 t DM ha-1 , respectively. However, there were no significant differences (p ≤ 0.05) in DM yields of A. donax between treatments. Thus, control of M. donacis with insecticides would be unnecessary in bioenergy crops of A. donax in this region.

“…The LC 50 value of chlorpyrifos was 15.90 (mg a.i. L −1 ) for the third instar larvae, which is less than the recommended field concentration [ 42 ]. The developmental period of third instar larvae was shortened following LC 10 treatment, whereas LC 30 treatment prolonged this period.…”

“…Chlorpyrifos treatment prolonged the developmental period of larval and pupal stages in comparison with that of the control because, after treatment, most of the energy in a treated individual was used for detoxification of the applied chemical [ 63 ]. In another study, chlorpyrifos treatment also increased the larval and pupal developmental period of H. convergens [ 42 ]. Similar results were reported in a study showing the adverse effects of chlorantraniliprole on H. axyridis [ 35 ].…”

“…Similar to other phosphorus compounds, chlorpyrifos induces oxidative stress, damages DNA, and inhibits acetylcholinesterase (AChE) [ 41 ]. Adverse effects from the use of this insecticide include negatively affecting non-target beneficial arthropods, such as coccinellid predators e.g., the convergent ladybeetle Hippodamia convergens [ 42 ], pollinators [ 43 ], parasitoid wasps e.g., Trichogramma brassicae [ 44 ] and other natural enemies e.g., the dipteran parasitoids Eibesfeldtphora trilobata and Apocephalus setitarsus [ 45 ].…”

Except of pest control, insecticides have shown adverse effects on natural enemies as well. Thus, risk assessment of pesticides for biological control agents is critical for effective use in integrated pest management (IPM) schemes. In the present study, the lethal and sublethal effects of chlorpyrifos, a commonly used insecticide that may negatively affect biological control agents, were evaluated on a non-target predator, the Asian ladybeetle Harmonia axyridis. Previous studies have reported on lethal concentrations, but the effects of sublethal concentrations remain unclear. Lethal and sublethal concentrations of chlorpyrifos were applied to third instar larvae of H. axyridis, and different growth and developmental parameters were measured. Treatment with LC10 (4.62 mg a.i. L−1) significantly shortened the developmental period of third instar larvae, whereas it significantly prolonged those of fourth instar larvae and pupa. Treatment with LC30 (9.59 mg a.i. L−1) significantly increased the larval and pupal developmental period compared with that of the control, whereas feeding potential, female fecundity, and adult longevity significantly decreased after LC10 and LC30 treatment. The pre-oviposition period significantly increased compared with that of the control. Population growth parameters, the finite (λ) and intrinsic rate of increase (r) and the net reproductive rate (R0), decreased following exposure to sublethal concentrations of chlorpyrifos. According to the results, the use of chlorpyrifos in IPM schemes requires further research because even sublethal concentrations of this insecticide were harmful to H. axyridis population growth.

This study aimed to examine the effectiveness of some insecticides on the population development and attack Liriomyza sp on local Palu onions. The research conducted from Februari to April 2017, at Guntarano village, Tanantovea Sub-District, Donggala District. The study used Randomized Block Design (RAK) consisting of four treatments, namely Po.Control; P1. Abamectin; P2. Azadiractin; P3. Dimohipo. Each treatment was repeated three times so that 12 treatments were obtained. The results showed that the insecticidal treatment had an effect on the development of the varied Liriomyza sp. Adult population at various plant age levels. Observations on plant age 5 and 6 of MST showed that abamectin insecticides were effective in suppressing the growth larvae populations of Liriomyza sp compared with the treatment of Azadiractin, Dimohipo and non-treated insecticides.
