A Comparative Study of the Effect of Some Mineral and Plant Oils on the Two Spotted Spider Mite Tetranychus urticae Koch (Acari: Tetranychidae)

Abstract

The direct toxicity of some mineral and plant oils to the eggs and females of the two spotted spider mite Tetranychus urticae Koch was tested. KZ oil was toxic to the egg stage compared to adult female. In contrast, Natur'l oil has a close toxic effect for both stages of T. urticae. Bio-dux oil was proved to be toxic to adult female and relatively in toxic to egg stage. Females of T. urticae suffered a depression in reproduction and shortened longevity when kept on plant leaves previously treated with different oils. Laboratory studies indicated that the vegetable oil Natur'l oil was effective on all biological aspects of T. urticae studied.

Bio-efficiency of some Aromatic Oils and Other Compounds on Some Biological Aspects of Tetranychus urticae as Alternative to Pesticides.

“…2) demonstrated that natural oil (Nat-1) affected on mortality percentage of stages was high and the represented value was (33.33%) compared to control. These results in an agreement with Rock and Crbtree(1987) they reported that petroleum oil more effective on the adult female of T. urticea than cotton seed oil , Amer(2001) who mentioned that vegetable oil Natural 1 has toxic to the adult female. Also, many authors had reported that mineral and botanical oils had height efficiency against spider mites (Lancastes et al (2002) and Lee et al (2005), Magouz and Saadoon (2005) they reported that two mineral oils, Alkanz 2000 oil and Natcom (20/5) oil affected by different percentages of mortality on the quiescent larva, of T. cucurbitacearum ,active proto-nymph ,quiescent proto-nymph active and deuto-nymph of T. cucurbitacearum but by small percentage .…”

“…of Carnation oil on the percentage of reduction eggs, T. urticea was slight effect where the percentage of reduction was (5%) with compared to control. These results in contrast with El -Duweini and Sedrak(1997) they found that jojoba oil (Nat-1) oil when sprayed on eggs T. urticea affected on hatchability of T. urticea and also with Amer et al (2001) they found that Bio-duxoil and Kz oil were toxic to eggs of T. urticea when eggs treated with them. Also with Roh et al (2004) and Mead (2012) they mentioned that (Lc 50 ) conc.…”

“…While Basil oil had no effect on eggs hatchability with compared to control . These results in contrast to (EL-Duweini and Sedrak (1997), Gamieh et al (2000), Amer et al(2001), Magouz and Saadoon (2005), (Sertkaya et al (2010), Ismail and Abo Ghalia, 2011, Mead, 2012and Elsadany ,2020 where those mentioned that mineral oils as jojoba oil, Super Masrona oil, Natcom oil (20/5) and (Nat-1) oil causes high reduction to T. cucurbitacearum and T . urticae eggs .…”

Effect of Some Mineral Oils Alone and Their Mixtures with Cyhalothrin on The In Vitro Activity of Adenosine Triphosphatase Enzyme (ATPase) Extracted from Spodoptera Littoralis Larvae Brain

“…El- Halawany et al, (1987) who reported Mineral oil used successfully on citrus trees against both of tested insects. Amer et al, (2001) found that Kz oil more toxic against Tetranychus urticae. Also Hazzard et al, (2003) reported the Mineral oil alone provided better control of Spodoptera fumgiperda (Lepidoptera: Noctuidae) compared with corn oil and B. thuringiensis.…”

Alternatives to a Pyrethroid for Controlling Madeira Mealybug (Hemiptera: Pseudococcidae) on Coleus Cuttings

“…for applying herbicides, fungicides, and insecticides. The insecticidal properties of Natur'l oil are well known, as it has been used effectively to control pests such as whiteflies and mites (Butler et al 1993;Liu & Stansly 2000;Amer et al 2001). Several vegetable oils, in addition to soybean oil, also are toxic to soft-bodied insects (Butler & Henneberry 1990;Pless et al 1995).…”
