Problems solved by technology

However, such a solution would not solve the larger infestation problem at hand, since these solutions only trap these pests
Additionally, these bonded devices are fraught with additional challenges
Typically, these devices are not reusable items once they become saturated with immobilized pests, and / or the adhesive may lose its effectiveness due to dust and other contaminants

[0255] Example 1 : Mortality of adult bedbugs when exposed to different entomopathogens

[0256] An adult population of 50% males and 50% females was fed for five days prior to testing. This ensures that the insects are hydrated and their nutritional needs are met.

[0257] These insects were exposed to the strain Metarhizium anisopliae strain F52 (F52) and two strains of Beauveria bassiana: Beauveria bassiana ATCC 74040 (Bb40) and Beauveria bassiana ATCC 74250 (Bb50). One (1) mL dilution of each isolate was made in an aqueous solution of 0.05% Tween 80 and confirmed by a hemacytometer combined with germination counts to correspond to 1 x 10 6 , 1x 10 7 , 1x 10 8 , and 1x 10 9 Viable spores / mL. These 1 mL dilutions were pipetted into 6.0 cm by 1.5 cm Petri dishes (Whitman No. 1, 5 cm diameter) fitted with filter paper. Four (4) bed bugs (2 males and 2 females) were placed in each petri dish and allowed to crawl in the dish for 30 minutes (plate 1). Controls (Chk) were...

[0275] Example 2: Effects of Different Entomopathogens on Bedbug Eggs and Nymphs

[0276] Bedbug eggs were exposed to the strain Metarhizium anisopliae strain F52 (F52) and two strains of Beauveria bassiana: Beauveria bassiana ATCC 74040 (Bb40) and Beauveria bassiana ATCC 74250 (Bb50). Dilutions of each isolate were made in an aqueous solution of 0.05% Tween 80 and confirmed by a hemocytometer combined with germination counts to correspond to 1 x 10 in 0.05% Tween 80. 7 and 1x 10 8 Viable spores / mL. A solution of 0.05% Tween 80 was used as a control.

[0277] Four (4) bed bug eggs were placed in each 6.0 cm by 1.5 cm petri dish fitted with the 1.5 cm diameter filter paper. Petri dishes were replicated 5 times for each treatment. Shake the dilution well to suspend the microparticles in the test solution. A 0.25 ml sample of each concentration was pipetted into a 6.0 cm x 1.5 cm petri dish containing the eggs. The Petri dish was ventilated for 4 hours to allow excess moi...

Abstract

Disclosed herein are pest controlling compositions comprising entomopathogenic fungi which are horizontally transmissible across pest populations and control target pests at various life stages. Further disclosed are methods of using such compositions for controlling pests, including, bed bugs and other invasive parasitic pests.

Description

field of invention [0001] Disclosed herein are insect control compositions that include entomopathogenic fungi. Also disclosed are methods of using such compositions for controlling pests, including bed bugs and other invasive parasitic pests. Background of the invention [0002] Pest infestation is a common problem in domestic and industrial settings, as well as in the agricultural industry. A number of products are available for controlling arthropod pests (eg insects) and for preventing new infestations. However, bed bug infestation has proven to be particularly difficult to eradicate. Bed bugs infest residential properties, such as homes and hotels, in a variety of ways. Bedbugs and eggs can be obtained from other infested dwellings through the clothing or luggage of visitors to pets or people, from nearby dwellings (through plumbing systems or false flat roofs), or from wildlife that can also harbor bedbugs (such as bats). or birds) without inadvertent spread.
