The literature pertalOlOg to the bionomics of some of the mos t important tetranychids is r~viewed. Considerable attention is paid to the possihiliries of spider mites reaching pest le~els /as a 'resu lt of environmental factors. It is concluded that more infor--m ation is needed on economic injury levels of various species on d ifferent crops and under various climatic conditions. The in-I fluences of cultural practices and their interactions as related to population development of tetranychids also need more i tu dy. Furthermore, work is need~d on the influence of climatic conditions on development of retranychid mite populations together with possible predictability 'of outbreak situations. Finally; we need to know more about ·th)e fundamental relations between the host-planr-qualiry and spider mite development, and the, impact of spider mites on the development .of their .host p lants.

“…1, 2) necessary t o interpret from the different treatments since predators were effective on some plots and miticides applied to others, providing different levels of mites throughout the season. Parent and Beaulieu (1957) in Quebec and Newcomer and Yothers (1929) in the Pacific northwest concluded up to four generations can be found at the same time during the season. Individuals of the first and second generations are easily separated as there is a period when only the adults of the first generation and eggs of the second are present.…”

Carz. Ent. 102: 64-68 (1970) Field populations of the European red mite, Panonychus ulmi (Koch), in Nova Scotia were separated into eggs, larvae, protonymphs, deutonymphs, and adults and the length of time each stage was present for each generation was determined in 1967 and 1968. The duration of each generation was similar in both years, although the diapause eggs hatched later in 1967 than in the succeeding year. Detailed information on the seasonal history is necessary in assessing red mite mortality and in timing of chemical controls of this pest. AbstractCan. Ent. 102: 68-84 (1970) Egg production in Neodiprion mainei may be severely reduced by food quality and quantity, tachinid parasitism, and prolonged diapause. Since these and other agents may affect the sawfly both lethally and sublcrhally and may operate

“…A crude measure of population persistence at the spatial scale of the tree was obtained for P. ulmi by determining the number of populations within each treatment that were still present, as determined by the presence of at least one non-zero sample from the tree (Parent and Beaulieu 1957), and thus "disappearance" of a population prior to this suggests that it has been driven to very low levels by some factor other than the exodus of adult females to lay winter eggs. Treatments were compared using the log-likelihood ratio contingency table test.…”

How Quality of Host Plant Affects a Predator‐Prey Interaction in Biological Control

In cases of successful biological control the pest population is maintained at low densities by a natural enemy, but the mechanisms by which the predator or parasitoid manages to control the pest are often unknown. This study was undertaken to determine the response of a predator to different population growth rates of its prey within a biological control system. Population growth rate of the phytophagous mite Panonychus ulmi was varied by altering the nutritional status of the host plant (apple trees [Pyrus malus]). NPK fertilizer was added to the soil, resulting in higher nitrogen, lower phosphorus, and lower potassium levels in the foliage of the trees. There appeared to be nonlinear relationship between nitrogen and P. ulmi densities, with density increasing and then decreasing as nitrogen concentration was increased. Two predaceous mites, Typhlodromus pyri and Zetzellia mali, were implicated in the control of P. ulmi, but the effectiveness of both was reduced at high nitrogen levels. The predators therefore did not fully compensate for increases in the population growth rate of their prey, although P. ulmi densities were maintained well below the economic threshold in all cases. However, the probability of persistence of the prey populations was not significantly affected by the nutrient regimes, suggesting that the fundamental dynamics of the predator—prey interaction were not altered by the range of population growth rates in this study.
