“…Due to considerable inertia, the control activity of such baits should be set back 1-3 months after their application and depositing more baits should bring no advance. Target populations will continue growing throughout the lag time exactly as recorded in our field experiment with a real bait (Zeman et al, 1992).…”

“…In our previous experiments in residential buildings, however, a yearly feeding on baits caused 97.5 Yo reduction of cockroach population while sterility ranged between 70-80~o. The population depression was markedly accelerated in flats with low insect density (Zeman et al, 1992).…”

“…This paper presents computer simulations of possible impacts of juvenoid feeding on a German cockroach population. These simulations were performed to better interpret our data on a juvenoid bait's efficiency (Zeman et al, 1992) and it was hoped they might lead to improved applications ofjuvenoids in the field.…”

A computer model was applied to simulate responses of German cockroach populations to feeding on juvenoid baits during an equilibrium, exponential, and the earliest phase of population growth. The simulations show that the renewal potential of the cockroach populations will be exhausted when about 80% or more adults become sterile. The attainment of this activity threshold will be preceded by a lag time with no apparent control effect. The time delay appears substantially shorter for both growing populations (30–60 days) than for the equilibrious one (90–120 days), but, the former ones will continue growing throughout this lag. The simulations predict that even a worse baits' performance can give sufficient control effect in the field if the baits are laid in an early phase of population growth. Thus, optimum tactics should integrate administration of juvenoid baits with an introductory reduction of cockroach population.

“…Other recent studies with baits include the incorporation of juvenoid bait formulations for the control of cockroaches [245], incorporation of entomophagous nematodes into food baits for control of black cutworms and tawny mole crickets [246], and development of baits for soil dwelling insects in sunflower [247]. Other studies have focused on combining food-baited traps with pheromone-baited traps [12,13,248].…”

Chemical communication is important in the life cycles of many insect species, principally for the location of mates and food. Structural identification and synthesis has been carried out for many semiochemicals, and a number of techniques have been developed to use these compounds as components of integrated pest management (IPM) programs. Semiochemicals have two main uses in IPM programs: monitoring insect pest populations and preventing agricultural damage by interfering with insect behavior. Pheromones are perhaps the most widely exploited semiochemicals at present, but recent efforts have extended increasingly to the identification and use of compounds involved in interspecific exchange of information as well.The use of semiochemicals to manipulate insect behavior has proved to be one of the most useful components of integrated pest management (IPM) programs. Semiochemicals are compounds that are emitted or displayed by one organism and that affect the behavior of another organism [/]. Perhaps the most important semiochemicals used by insects are those involved in locating mates and food, and at present these are the kinds of semiochemicals most widely exploited for insect control. Semiochemicals with many other kinds of ecological roles have also been characterized in insects, such as compounds that function as warnings, or compounds that mediate the collective activity of many partners in completing large tasks. A number of major reviews of the use of semiochemicals in IPM programs have appeared [7][8][9], as well as a critical review of semiochemical utility in general [10], An extensive list of companies that offer semiochemical lures, traps designed for semiochemical monitoring, and commercial systems for behavioral pest control has been compiled by Inscoe [11].Practical applications of semiochemicals in agriculture fall into two main categories, population monitoring and behavioral pest control. The main use at present is in monitoring insect pests with traps baited with semiochemicals, as a part of making decisions about pesticide application or other control techniques. A second use of semiochemicals is the direct prevention of insect damage by a variety of techniques, including the placement of a large number of semiochemical sources that disrupt the behavior of the insects, mass trapping, attracticides (insecticide lures), and enhancement of parasitoid activity.

“…São muitas as pesquisas que comprovam a eficiência da atividade inseticida dos IRC sobre Blattella germanica em laboratório e em campo, tornando esses produtos indicados para a incorporação em programas de controle pragas (Riddiford et al, 1975;Schal & Hamilton, 1990;Bennet & Reid, 1995). Dentre os mais estudados estão os inibidores de síntese de quitina (DeMark & Bennett, 1989;Reid et al, 1992;Aguilera et al, 2001) e os análogos do hormônio juvenil ou juvenóides (Bennett et al, 1986;Brenner et al, 1988;Kramer et al, 1990;Koehler & Patterson, 1991;Zeman et al, 1992).…”

It was evaluated the effect of Metarhizium anisopliae and the insect growth regulators triflumuron and pyriproxifen for adults and nymphs of the German cockroach Blattella germanica, and the efficacy of its association in the control of this urban pest. High doses of the pathogen caused high mortality of adults and nymphs. There was no mortality of B. germanica nymphs exposed for 72 hours to the food contaminated with M. anisopliae. The mortality of adults and nymphs was of 93.7% and 82.3%, respectively, when exposed to a surface that had been contaminated with the fungus formulation (5%), as early as 9 days after the application. The LC 25 for nymphs exposed for a 72-hour period to the triflumuron-bait was 0.19% (active ingredient) and for pyriproxifen-baits 0.45%, after 15-day period. Both inseticides decreased the production of viable oothecae and the number of nymphs in this cases. Untreated colonies presented 6.55 fold in the number of insects after a 60-day period, with 233.9 average insects per colony. The colonies exposed to triflumuron and pyriproxifen had an average of 60.8 and 81 insects, respectively. The insecticides and fungus association presented populations of 41.8 and 57.7 insects for triflumuron + M. anisolpiae and pyriproxifen + M. anisopliae, respectively. Two applications of the association of M. anisolpiae and
