Efficacy of modified atmosphere packaging to control Sitophilus spp. in organic maize grain BABT
Carli,Marcelo De; Bresolin,Bruna; Noreña,Caciano Pelayo Zapata; Lorini,Irineu; Brandelli,Adriano.
The effect of modified atmosphere packaging on the mortality of Sitophilus spp. in organic maize grain was studied. Maize grains were packed with five different atmospheres consisting of 20% O2, or 20, 40, 60, 80% CO2 with remaining N2. The packages were stored for 30 days at 26°C. CO2 and O2 concentrations were monitored inside the packages during the storage. The moisture content, titratable acidity and pH were analysed on the first and thirtieth day. At 5, 15 and 30 days of storage no significant differences were observed in the percentages of dead insects when CO2 was used. The results of progeny indicated that from the fifth day the number of emerging insects was low at 20, 60 and 80% CO2. Complete inhibition of the insects was achieved with 30 days...

Insecticidal action of Drimys brasiliensis Miers on black citrus aphid Rev. Ciênc. Agron.
Anese,Simoni; Gambarra,Wanessa Porto Tito; Grisi,Patrícia Umeda; Gualtieri,Sonia Cristina Juliano.
ABSTRACT The aim of this study was to evaluate the insecticidal effects of a hexane fraction and polygodial compound obtained from Drimys brasiliensis roots on the mortality of adults and nymphs of Toxoptera citricida (black citrus aphid). For the hexane fraction, solutions of 0.12, 0.25, 0.50, 1.0, and 2.0 mg mL-1 were prepared, and for the compound, solutions of 62.5, 125, 250, and 500 µg mL-1 were prepared. A control with water and dimethylsulfoxide (5 µg mL-1) was also included. Two hexane-fraction-solution application methods were evaluated: spraying directly onto the insect, and submerging a young Citrus limonia shoots in the solution, which served as a refuge for the aphids. Nymph and adult mortality were assessed at 24 and 48 h after solution...
