Natural enemies of tetranychid mites on citrus and avocado in southern California. a. Plant species vary in their degree of acceptance by the mite population. The physicomorphic leaf characteristics may have either a negative or positive influence on the pest population as well as their natural enemies (Krips et al., ). Strong webbers such as Tetranychus spp. prefer rough surfaces to smooth ones. Leaf hairs could serve as a.

    Some biological effects of gamma radiation on the two-spotted mite, Tetranychus urticae Koch were determined. A substerilizing dose given to a male subsequently mated to a normal female caused sterility in the F1 female progeny. LD50/10 values for adult males and females were established at 90 and krads, respectively. Eggs were more radioresistant as they aged; 3, to 3, rads were. First, I quantified spider mite, Tetranychus urticaeKoch (Acari: Tetranychidae), population growth on individual host plants over a gradient of nitrogen availability.

    Introduction. It is now well recognized that host plant quality can affect several life-history characteristics of their herbivores, by impairing growth, lowering resistance to disease and reducing fecundity (Price et al. ).Alteration of population growth results from changes in fecundity, survivorship and development rates of the herbivore ().   Except for the records after 1 and 48 h, percentage of T. urticae present on transgenic and control half-discs during five days was biased with more mites observed on the leaf disc halves from Bt-eggplants ().The percentage of spider mites found on Bt halves ranged between and %. Mean number of observations (x ¯ ± SD) at which an individual T. urticae female was found on Bt and .

Population growth studies were conducted with Tetranychus telarius (Linnaeus) on lima beans in the greenhouse. The capacity of populations to increase was studied in relation to host-plant nutrition, leaf age and plant age.

The higher LMA and photosynthetic capacity results in an increased amount of mesophyll per unit leaf area. This would allow the mites to feed efficiently from a limited area, which may explain the increased fecundity on these leaves.

Species of the thripid genus Scolothrips are well known as predators of mites, such as Tetranychus urticae (Gilstrap, ; Pakyari et al., ), occurring on leaves of various plants (Gilstrap.

Notes on Taxonomy and Nomenclature Top of page Tetranychus urticae is part of a group of very similar species in the genus Tetranychus. At one time, a species complex included about 60 synonyms, each described from different hosts or from different parts of the world, the best known of which were Tetranychus telarius L., Tetranychus bimaculatus Harvey and Tetranychus altheae von Hanstein.

Influence of Host Plant Characteristics on Predatory Mite Survival. The performance of natural enemies is also influenced by host plant characteristics (Lester et al., ). Leaf surface texture and vestiture affect the performance of acarine predators associated with plants.

This study compared population growth parameters of Tetranychus urticae Koch on 10 rose cultivars, including Bella Vita, Cool Water, Dolce Vita, Maroussia, Orange Juice, Pink Promise, Roulette, Tea, Valentine, and Persian yellow in laboratory conditions at 24+/-1°C, 65+/-5% relative humidity, and a photoperiod of (L:D) h.

17 August Kiran 31 Profuse plant growth due to high nitrogen fertilizer retards spray coverage. Excessive dose of nitrogen fertilizer produce lush green plants, which will attract pest population. Plants given nitrogen fertilizer increases plant dry weight, leaf area, leaf chlorophyll content and grain yield.

Increase in nitrogen increases. Taken together, our results show that the host plant species can affect critical parameters of population dynamics, and most importantly that maternal and environmental conditions can facilitate colonization and exploitation of a novel host in the polyphagous T.
