The diets included mustard aphid (Lipaphis erysimi), 2nd instar mealybug (Phenoccocus solenopsis), Eggs of angoumois grain moth
(Sitotroga cerealella) and honey.
The fecundity, fertility, pupation, hatchability and longevity of the predator were also higher on aphids followed by pink and spotted bollworms, and Angoumois grain moth
Losses due to infestation by the angoumois grain moth
have been increasing along with the greater yields and amount of cereal grains being stored in farmer households since the 1980s; in some areas, this insect alone can account for over 40% of the total losses in stored grain.
2: Percentage of operations that named one of the following arthropods as causing problems in stored rough rice in the past 5 years: Angoumois grain moth
, Sitotroga cerealella (Olivier); Indianmeal moth, Plodia interpunctella (Hübner); lesser grain borer, Rhyzopertha dominica (Fabricius); mites; red flour beetle, Tribolium castaneum (Herbst); rice weevil, Sitophilus oryzae (Linnaeus); spiders or wasps.
Exploitation of newer botanicals as rice grain protectents against Angoumois grain moth
To minimize the infestation level of sugarcane stem borer, Trichogramma chilonis (Ishii) (Hymeoptera: Trichogrammatidae) was reared on a fictitious host, stored grain pest Angoumois grain moth
Sitotroga cerealella (Olivier) (Lepidoptera: Gelechiidae) in the laboratory of Ayub Agriculture Research Institute, Faisalabad, under controlled temperature 252C and relative humidity 60-70% and released in the field as bio-control agent.
Among the more important pests are the granary weevil, rice weevil, lesser grain borer, Angoumois grain moth
, confused flour beetle and the saw-toothed grain beetle.
