چکیده
Efficacy of methoprene applied at different temperatures and rates to surface substrates to control eggs and fifth instars of Plodia interpunctella Hubner Methoprene is an insecticide that is used in pest management programs for stored grains, and works by inhibiting the molting process of insect larvae. Methoprene is effective on stored-product beetles, but there are comparatively fewer data regarding effectiveness on the Indianmeal moth. We conducted tests by exposing eggs or larvae of the Indianmeal moth on packaging materials or flooring surfaces treated with methoprene. Eggs of the Indianmeal were not susceptible to methoprene. However, depending on the specific packaging material and the time of exposure, larvae were susceptible and most of them did not reach the adult stage after they were exposed to methoprene. An economic analysis showed the risks and benefits associated with methoprene treatment, and results of the tests and the budget analysis show that methoprene could be used in pest management plans to control larvae of the Indianmeal moth.

Efficacy of methoprene applied at different temperatures and rates on surface substrates to control eggs and fifth instars of Plodia interpunctella.
A series of studies was conducted to determine the effects of temperature on toxicity of the insect growth regulator methoprene to eggs and larvae of Plodia interpunctella (Hübner), the Indianmeal moth. When methoprene was applied to Kraft paper at the rate of 0.0003 mg of active ingredient [(AI)]/cm2, there was little direct toxicity against eggs of P. interpunctella, and temperature did not a...

Heating the ambient air of a whole, or a portion of a food-processing facility to 50 to 60 degrees C and maintaining these elevated temperatures for 24 to 36 h, is an old technology, referred to as heat treatment. There is renewed interest in adopting heat treatments around the world as a viable insect control alternative to fumigation with methyl bromide. There is limited published information...

Aerosol insecticides (also known as ULV or fogging treatments) delivered through an ultra-low-volume application system, are available commercially to control insect pests such as Plodia interpunctella Hübner, the Indian meal moth. However, little is known about the susceptibility of eggs of P. interpunctella to aerosol insecticides applied in active field sites. We conducted several trials by ...
متن کاملCombination of Methoprene and Controlled Aeration to Manage Insects in Stored Wheat
A commercial formulation of the insect growth regulator methoprene was applied to wheat stored in small bins either alone or in combination with controlled aeration of the bins, to lower grain temperature for insect pest management of stored wheat. Grain temperatures were monitored and modified by a computer-controlled thermocouple system that also activated the aeration system at programmed se...
متن کاملEconomic feasibility of methoprene applied as a surface treatment and as an aerosol alone and in combination with two other insecticides.
Economic evaluations of integrated pest management strategies are becoming increasingly important as restrictions on conventional insecticides continue to become more stringent and chemical control costs rise. Aerosol treatments with insect growth regulators alone and in combination with conventional contact insecticides may be a feasible alternative to expensive and highly toxic fumigants such...
