Soldier bug (Podisus maculiventris) is an excellent general predator, it can prevent and control Caterpillars, Loopers, Cucumber beetles and over a 100 other species of pests. As an adult, it is very mobile and can spread very quickly through the field or greenhouse by walking or flying in search of food. Females lay up to 1000 eggs in its lifetime and can live up to 5-8 weeks. It is predatory in all 4 of its 5 stages. Podisus does diapause in the field but can be used year-round in greenhouses if the light is more than 10 hours and the temp is higher then 20ºC.
Podisus can work in a wide range of temperatures but prefers a warm and humid environment (25ºC and over 60% RH). It will become inactive if temperatures drop under 16ºC. Podisus is known to work very well in outdoor fields, greenhouses, hydroponics, interiorscapes, container plants and much more
Podisus is very easy to spot with the naked eye due to its size and is normally found on the top foliage of the crops. Scouts need to be aware that Podisus appearance changes considerably from the first instar to adult. Knowing what each stage looks like will help scouts determine how well the population is being established in the crops.

Release Rates and Tips:
4 - de Castro, A.A., et al. Survival and behavior of the insecticide-exposed predators Podisus nigrispinus and Supputius cincticeps (Heteroptera: Pentatomidae). Chemosphere (2013), http://dx.doi.org/10.1016/j.chemosphere.2013.05.075
Pesticide and Other Controls:
Use of pesticide can increase mortality of the beneficial insect. Deltamethrin, methamidophos and spinosad caused 100% mortality of predators. Chlorantraniliprole showed lower predator toxicity and higher selectivity. All of the insecticides sparked changes in the predator (walking) behaviour. Insecticide repellence was not observed for any compounds tested. Chlorantraniliprole use is advisable for IPM programs.⁴ If you have more question please contact us for a free consultation by one of our Ph.D. entomologist. We would love to help.
Release as soon as possible, preferably in the evening when the temperature is cooler and light is low. Release rate varies considerably depending on the crop, infestation level and season of the year. This is just a general release rate, please contact us here to create an IPM program that works for you.
