“…McKenzie and Puterka (2004) and Hall and Richardson (2013) showed that the use of insecticidal soap provided significant control of the psyllid pest population, Diaphorina citri Kuwayama, 1908. Insecticidal soaps usually caused meaningful, but short-period suppression of some important pests such as wheat aphid, Schizaphis graminum (Rondanni, 1852) (Nuessly and Nagata, 2005), the thrips of weeping ficus, Gynaikothrips uzeli Zimmerman, 1900 (Held andWheeler, 2007), aphid of the crepe myrtle, Tinocallis kahawaluokalani Kirkaldy, 1906 (Layton andGu, 2009a), whitefly of sweet potato, Bemisia tabaci (Gennadius, 1889) (Layton and Gu, 2009b) and the psyllid of pistachio, Agonoscena pistaciae Burckhardt andLauterer, 1989 (Kabiri andAmiri-Besheli, 2012). The maximal mortality percentage in surfactant treatment, dioctyl sodium sulfosuccinate, occurred in three days after spraying (Figures 1 and 2).…”

Aphis gossypii Glover, 1877 is a serious pest of cucumber in greenhouse plantings. Biorational insecticides are an alternative of broad spectrum insecticides for aphid suppression in greenhouse. In this regards, the efficiency of some biorational insecticides including soap based on coconut oil, surfactant based on sodium sulfosuccinate and antifeeding based on potassium nicotinate were assayed on A. gossypii in the cucumber greenhouse. The trials were set up in a randomized complete block design with four replications. Samplings were carried out one day before spraying and 3, 7, 14 and 21 days after spraying. The data were submitted to ANOVA and the means comparison was performed using Duncan’s test. The results indicated that the highest mortality in insecticidal soap, surfactant and antifeeding treatments occurred after 3 days, with 78.47 %, 67.16 % and 60.48 % mortality, respectively. The results of the trials are discussed in terms of improving management of the populations of A. gossypii.

“…Liquid formulations of insecticides registered for use in turfgrass are effective at controlling greenbugs (Nuessly & Nagata 2005). Insecticides applied as granules move downward into the thatch away from the greenbug's preferred feeding area up on the blades and are thus ineffective at controlling this aphid.…”

The greenbug, Schizaphis graminum (Rondani), has been recognized as a major pest of small grains for over 150 years. Described by Rondani, it was first placed in the genus Aphis (Rondani 1852) and later moved to the genus Toxoptera. There are about 40 recognized Schizaphis species worldwide with seven known from North America (Blackman and Eastop 2000). This document is EENY-353, one of a series of the Entomology and Nematology Department, UF/IFAS Extension. Published: July 2005. EENY-353/IN634: Greenbug, Schizaphis graminum (Rondani) (Insecta: Hemiptera: Aphididae) (ufl.edu)

“…McKenzie and Puterka () included an insecticidal soap treatment in a field study and reported the soap caused moderate to high mortality of ACP. Soaps are generally reported to provide significant, but short‐term, control of some insect pests such as the crape myrtle aphid [ Tinocallis kahawaluokalani (Kirkaldy)] (Layton and Gu ); greenbug [ Schizaphis graminum (Rondanni)] (Nuessly and Nagata ); sweetpotato whitefly [ Bemisia tabaci (Gennadius)] (Layton and Gu ); and the weeping fig thrip [ Gynaikothrips uzeli (Zimmerman)] (Held et al. ).…”

Toxicity of insecticidal soaps to the Asian citrus psyllid and two of its natural enemies

The Asian citrus psyllid (ACP), Diaphorina citri Kuwayama (Hemiptera: Psyllidae), is an important pest of citrus because it transmits plant pathogens responsible for a serious disease of citrus known as huanglongbing. Conventional insecticides are frequently used to manage ACP. Insecticidal soaps (hereafter ‘soaps’) are an insect control option labelled for commercial use as well as for use by homeowners and organic growers. Soaps have been shown to be toxic to some insect pests and therefore might be an alternative to conventional pesticides for control of ACP, but the efficacy of soaps against ACP was largely unknown. Our objective was to test whether different concentrations of two insecticidal soaps, M‐Pede and Safer Insecticidal Soap Concentrate, caused mortality of ACP adults, nymphs and eggs. In addition, we tested whether these soaps were toxic to two natural enemies of ACP, adults of the lady beetle Cycloneda sanguinea (L.) (Coleoptera: Coccinellidae) and the parasitoid Tamarixia radiata (Waterston) (Hymenoptera: Eulophidae). Direct sprays of M‐Pede or Safer Insecticidal Soap were acutely toxic to ACP adults (regardless of gender) and nymphs when applied in solutions of 0.8–2% in water. Insecticidal soaps were non‐toxic to eggs at rates of up to 2%. Residues of soap were less toxic to adult ACP than direct sprays, even when applied at concentrations of up to 4%. M‐Pede or Safer soap at high concentrations (for example, 2% v/v in water) may be an effective alternative to conventional pesticides to manage adult and nymphal ACP, although multiple applications may be needed if a target population includes eggs. A 2% concentration of either soap applied as a direct spray was non‐toxic to adult C. sanguinea but acutely toxic to adult T. radiata. Soaps therefore may be compatible with biological control of ACP by adult coccinellids but not the parasitoid T. radiata.
