Prairie Provinces

In the Prairie Provinces, newlv harvested grain is seldom infested with stored grain insects and mites when first binned. During the storage period, infestation of grain depends on 1, the proximity and abundance of stored grain pests, 2, the ability of the insects to gain a foothold and cause extensive damage, and 3, the initiai storage condition of the grain. The latter, in turn, is influenced bv temperature, moisture content and the amount of grain dust, chaff and weed seeds present.

Stored Grain Pests

Abstract Background Stored grain products suffer a considerable economic loss due to insect infestations. The resistance of pests to insecticide, and residues on crops are produced by the application of insecticide. Nowadays, incremental necessity has been occurred to find out alternatives to chemicals. As biological control agents, entomopathogenic nematodes (EPNs) attract attention increasingly in the research area recently. Results The aim of the study was to evaluate the pathogenicity of Pakistani isolates Steinernema bifurcatum and S. affine against the stored grain pests, Tribolium castaneum and Lasioderma serricorne, under laboratory conditions. Suspensions of nematodes were applied at 4 different concentrations 0, 50, 100, and 200 IJs/ml and 3 variable temperatures 15, 30, and 45°C. Pathogenicity rate was recorded after 48 h of application. The larval stage is found more susceptible than the adult. At 200 IJs, S. bifurcatum showed high mortality of L. serricorne larva (92%) and T. castaneum larva (93%), whereas S. affine showed 90 and 95% mortality of L. serricorne and T. castaneum larva, respectively, at 200 IJs. The results revealed that both species of EPN were able to control and reproduce on L. serricorne and T. castaneum. Maximum mortality was recorded at 45 °C from S. bifurcatum whereas S. affine at 15 °C. Conclusions Therefore, S. bifurcatum and S. affine could be suggested as a biological control agent for hot and cold climatic zones, respectively.

Theobroma Cacao L

Clonal plants that produced by somatic embryogenesis technique is one of the best choice to produce supperior clonal cacao (Theobroma cacao L.) planting materials. The somatic embryogenesis technique is a possible way for massive propagation, the outcome is true to type plants, the architecture similarity that the seedlings but there is not segregation like seedlings plants. At present mass production started of plantlets production until post-acclimatized plantlets of somatic embryogenesis cocoa was done at Indonesian Coffee and Cocoa Research Institute. Distribution system of the planting materials to whole areas in form of as up-rooted post-acclimatized plantlet. Some problems identified to reduce probability of decreasing viability of up-rooted post-acclimatized plantlets and one of them is extreme internal water deficit. This research investigate of the influece storage condition (air tight and non-air tight) and box storage (mica plastic and cardboardbox). The first experiment result show, there is no significant different between mica plastic and cardboard box usage for storage of post-acclimatized cocoa pantlet. Viability of up-rooted post acclimatized cocoa plantlet influenced exactly by air tight and non-air tight storage condition. Air tight storage condition have better viability of up-rooted post acclimatised (81,58%) than non-air tight storage condition (65,00%). Leaf sanasence on air tight storage condition (10,33%) lower than non-air tight storage (32,58%). There is not significantly on volume storage per plantlet between 4.416 cm3 and 12.600 cm3. Relationship between fallen leaves and cocoa planlet viability follow negative linear correlation y = -1,4719x + 104,88 (R2 = 0,9772). The second experiment treatment showed that maximal storage periode of post cclimatized cocoa plantlet just until 6 days stored (97%) and not significant with 3 days one. Viability of post acclimatized cocoa plantlet decreased after 6 days storage period.Key words : Somatic embryogenesis, post acclimatized cacao plantlet, storage condition, box storage, volume storage, storage period and viability.
