ABSTRACT. A study was made of Aleiodes species recorded in Mexico, and specimens deposited in various collections. Using the criteria of Portier and Shaw (1999), eight species groups were recognized from Mexico, with 21 described and 27 undescribed species recorded. These are first records in Mexico for A. earinos Shaw, A. graphicus (Cresson), A. notozophus Marsh and Shaw andA. politiceps (Gahan). The genus is widely distributed in Mexico, being present in 28 of 31 states. Results are discussed in relation to the richness patterns hypotheses of other authors.

  • Ichneumon Sub-Families This Page Describes the Different Sub-Families of the Ichneumonidae
    Ichneumon Sub-families This page describes the different sub-families of the Ichneumonidae. Their ecology and life histories are summarised, with references to more detailed articles or books. Yorkshire species from each group can be found in the Yorkshire checklist. An asterix indicates that a foreign-language key has been translated into English. One method by which the caterpillars of moths and sawflies which are the hosts of these insects attempt to prevent parasitism is for them to hide under leaves during the day and emerge to feed at night. A number of ichneumonoids, spread through several subfamilies of both ichneumons and braconids, exploit this resource by hunting at night. Most ichneumonoids are blackish, which makes them less obvious to predators, but colour is not important in the dark and many of these nocturnal ones have lost the melanin that provides the dark colour, so they are pale orange. They have often developed the large-eyed, yellowish-orange appearance typical of these nocturnal hunters and individuals are often attracted to light. This key to British species is a draft: http://www.nhm.ac.uk/resources-rx/files/keys-for-nocturnal-workshop-reduced-109651.pdf Subfamily Pimplinae. The insects in this subfamily are all elongate and range from robust, heavily- sculptured ichneumons to slender, smooth-bodied ones. Many of them have the 'normal' parasitoid life-cycle (eggs laid in or on the host larvae, feeding on the hosts' fat bodies until they are full- grown and then killing and consuming the hosts) but there are also some variations within this subfamily.

INFORMATION TO USERS This material was produced from a microfilm copy of the original document. While the most advanced technological means to photograph and reproduce this document have been used, the quality is heavily dependent upon the quality of the original submitted. The following explanation of techniques is provided to help you understand markings or patterns which may appear on this reproduction. 1. The sign or "target" for pages apparently lacking from the document photographed is "Missing Page(s)". If it was possible to obtain the missing page(s) or section, they are spliced into the film along with adjacent pages. This may have necessitated cutting thru an image and duplicating adjacent pages to insure you complete continuity. 2. When an image on the film is obliterated with a large round black mark, it is an indication that the photographer suspected that the copy may have moved during exposure and thus cause a blurred image.

In the present study, a Y-tube olfactometer was employed to investigate whether the parasitoid T. radiata is capable of utilizing the odour source emitted by both plants and insect hosts during its foraging. The odour sources included Murraya paniculata (L.) shoots, 1st, 2nd, 3rd, 4th, and 5th D. citri instar nymphs, both individually and in combinations. Moreover, nymph-stage choice for parasitism, including 3rd, 4th, and 5th D. citri instar nymphs, was carried out. The results indicated that female T. radiata were only significantly attracted to volatiles emitted by M.

Conclusions Related Chapters Glossary Bibliography Biographical Sketch 3.6 Agronomic and Ecological Performance during Transition to Organic Management The process of conversion of an agroecosystem from a high-input conventional management system to a low-external-input system can be conceptualized as a transitional process with three marked phases (Figure 6). Increased efficiency of input use as emphasized by traditional integrated pest management. Input substitution or substitution of environmentally benign inputs for agrochemical inputs as practiced by many organic farmers. System redesign: diversification with an optimal crop/animal assemblage, which encourages synergism so that the agroecosystem may sponsor its own soil fertility, natural pest regulation, and crop productivity. For scientists involved in transition research, an important outcome of these studies is the realization that the process of converting a conventional crop production system that relies heavily on synthetic, petroleum-based inputs to a legally certifiable, low-external input, organic system is not merely a process of withdrawing external inputs, with no compensatory replacement or alternative management.
