Entomol, 63(4):1292-1296. Releases of the coccinellid Chilocorus bipustulatus Linnaeus against the white date scale, Parlatoria blanchardi (Targioni-Tozzetti), in date palm oases at 700- to 1600-m elevation in northern Niger were most successful during the rainy season (Stansly, 1984); and Smith (1988) considered the effect of wind and other factors on the fate of T. minutum released inundatively against the spruce budworm. Wash. 99: PINTO, J. D., R. STOUTHAMER and G. R. PLATNER. Eric P. Caragata, Luciano A. Moreira, in Arthropod Vector: Controller of Disease Transmission, Volume 1, 2017. Proposed studies will re-evaluate generic limits and produce a phylogenetic classification of the family. Here, administration of various antibiotics or of high temperatures to thelytokous females led to the production of males among the offspring.

The mass-release component consisted of weekly releases of 100,000 T. pretiosum per hectare over a 5–9 week period. Physiol Entomol 16:313–327, Nordlund DA, Chalfant RB, Lewis WJ (1985) Response of Trichogramma pretiosum females to volatile synomones from tomato plants. Hassan SA, 1977. Thus, the biological characteristics of releases are important in evaluating biological control efficacy. A study on the control of mode of reproduction in Trichogramma was completed.

Reproductive compatibility studies and molecular analysis are continuing on collections made over the three year period. A similar program exists for managing H. armigera on processing tomatoes in New Zealand, except that the program relies on larval rather than egg parasitoids.

This work will also impact the various commercial insectaries which commonly provide species of this complex to growers and researchers. 1990. Env. Figure 13.4. 95: 105-111. The allozymic differences correlate with the crossing results. Williams et al. PINTO, J.D. Entomol. The scope of these interactions varies among infected hosts, and understanding these differences is a key part of deciding on the right strain. Compendium record. Indoxacarb is formulated on a 5–7 μm silica particle and may readily adhere to the body of the insect through antennal drumming behavior and general locomotory activity. Both species are available commercially from various insectaries. Registered in England & Wales No.

Also the museum holdings of the Riverside collection of Trichogrammatidae (excluding Trichogramma) had been databased several years ago and we continue to A review of the genus Doirania (Hymenoptera: Trichogrammatidae) with a description of a new species from North America. Incorporation of these parasitoids into tomato IPM programs, along with the use of compatible insecticides, led to a 95% reduction in insecticide use in New Zealand tomatoes (Cameron et al., 2009).

While this was effective in reducing fruitworm and armyworm damage, it did not improve control over the standard insecticide treatment. 9., Braumschweig, Germany: Federal Biological Research Centre for Agriculture and Forestry. The device provides protection from rain and from predators in the field. As Wolbachia are typically present at high density in the ovaries, infection can also cause a range of other effects on reproduction, including naturally increasing or decreasing fecundity, which is seen in the parasitoid wasps Leptopilina heterotoma and Trichogramma pretiosum.

The egg parasitoid Trichogramma achaeae Nagaraja & Nagarkatti has recently shown potential for use as a biological control agent of Tuta absoluta (Meyrick), a key pest of tomato crops worldwide.

This effort was virtually completed this year with the entry of almost 5000 records. 2) Studies have continued to clarify relationships among cryptic species of TRICHOGRAMMA that are not well differentiated morphologically. Appl. Tran LC; Bustamente R; Hassan SA, 1986. 1) A two-quarter sabbatical is currently being taken for work on the revision. For this reason trichogrammatid wasps are one of the most commonly employed enemies used in biological and integrated control. We have postulated, based on laboratory studies, that biological control efforts can be compromised if both species are released at the same site and allowed to interact reproductively.
