Shuddering, I listened to the guests conversing in the living room as I poured the water off as quietly as I could. The Maize weevil will breed on maize in the field, but the Rice weevil only breeds in stored grain. Grain weevils include three species of small weevils: The rice weevil, granary weevil and the maize weevil. The need to study and control insect pests has contributed to the development of artificial diets. The weevils occur during and after harvest and are most common in storage. Food limitation induces severe competition for obligate seed-feeding insect larvae that are unable to leave the seed selected by their mother. Both are internal feeders, which means the larva develops inside whole grain kernels. Most of the bugs and larvae flowed off into the sink. The eggs hatch into larvae, which eat the plant material surrounding them. The number of eggs laid per seed and the number of larvae hatched from the eggs are important determinants of whether larval behaviour within the seed will be of the scramble or the contest type. The larvae or grubs develop inside of whole corn, wheat and rice kernels. The bean stem weevil ( Alcidodes leucogrammus ), bores into the base of the stem of French bean (Phaseolus) or cowpea (Vigna) plants and lays a small number of eggs. They are common stored grain pests, which sometimes infest whole kernel grain foods in our pantries. Damage to grain caused by this weevil includes reductions in nu-tritional value, germination, weight, and commercial value5. They have densely spaced pits on the pronotum that are round (maize weevil) or elongated (rice weevil). Rice weevils and maize weevils are about 1/8 inch long and brown. The maize weevil is slightly larger, up to one-eighth inch (four mm) long, and darker than the rice weevil; the degree of variation within each species makes them difficult to tell apart. This organic concentrate is fast acting and safe enough to use on corn, tomatoes and more with just one day to harvest. The adult weevils emerge through tiny, round holes in the kernels. The maize weevil can be conventionally con- Maize weevil. https://www.pestnet.org/fact_sheets/maize_greater_grain_weevil_339.htm The two species look almost identical without magnification. Apparently I had rice weevils, which are in the same genus as wheat weevils but a slightly different species. Mating often occurs within 24 hours of adult emergence from grain kernels. Rice and Maize weevils are widely distributed in tropical and sub-tropical areas and will be carried to temperate areas on imported commodities. If this material is a crop plant or seeds used for human food, the weevils may cause serious damage. Adult weevils and larvae feed on undamaged grains and reduce them to powdery form ( Adedire 2001). Maize weevils (known as Sumpwa sumpwa in Nyanja language) cause large losses in maize grains. Their larvae hatch from eggs laid on to grains by weevils. Then a grown weevil rose to join its white larvae offspring. The larvae cause damage by boring into the grain, making holes and grinding it to a fine powder. Maize Weevil. Weevil adults attack whole grains, and larvae cryptically feed and develop within grains3. (Photo Credit: John Obermeyer) BIOLOGY AND BEHAVIOR. Maize weevils, for a long time were referred to as a larger strain or race of the rice weevil, but are now recognized as a distinct species. Both adults and larvae are coldhardy.
