A cavitation effect was observed during nitrogen adsorption/desorption measurements. A new pore system with approximately 3000 nm in diameter was formed among these clusters. The starting pore system with 150 nm diameter disintegrated during the transformation process because of the formation of MCM-48 clusters. The results confirmed the successful synthesis of MCM-48 particles with a hierarchical pore structure. The products were characterized by nitrogen adsorption, mercury intrusion, x-ray diffraction, scanning electron microscopy and light microscopy. The transformation process was controlled via different concentrations of cetyltrimethylammoniumhydroxide (CTAOH). Porous glass granules (100–200 μm particle size) with a pore diameter of 150 nm and a pore volume of 1.44 cm³/g were used as starting materials. This represents an advantage for applications as catalyst support. transfer inside the pores compared to the 2 dimensional MCM-41 pore system. Due to the cubic network of the MCM-48 structure, such materials are characterized by an improved mass. In this study we describe the synthesis of MCM-48 granules with a bimodal pore structure via pseudomorphic transformation of porous glasses. It was shown in previous publications that porous glasses can be transformed into MCM-41 materials with monomodal or bimodal (hierarchical) pore systems. Moreover, 20-OH-ecdysone induced in the fat body of males, in contrast to methoprene, synthesis of mRNA coding for YPs to a level as high as that in vitellogenic females, as shown in the reticulocyte lysate cell-free system. The trophocyte fat body cells of male Sarcophaga treated with 20-OH-ecdysone, display a similar granular type of immunoreaction with an anti-YP antiserum as in vitellogenic females. This antiserum specifically reacts with some storage granules of the persisting larval fat body cells and not with the other fat body cell types. An antiserum against the larval serum protein 1 of Drosophila crossreacts on immunoblotting with several polypeptide bands in the haemolymph. The yolk polypeptides (YPs) are localized in secretory granules in the cytoplasm of female trophocyte fat body cells while the oenocytes and larval fat body cells are immunonegative. The fat body of adult Sarcophaga bullata consists of different cell-types. The (S)-methoprene rate of 4.8 g/acre was effective in controlling adult emergence for up to 14 days after treatment. Emergence inhibition and statistical analysis showed that significant differences were found between the (S)-methoprene rates of 2.4 and 4.8 g/acre at each posttreatment assessment. taeniorhynchus at 1, 3, 7, and 14 days after treatment. Two application rates ((S)-methoprene at 2.4 and 4.8 g/acre) of the Aquaprene WP also were evaluated against Oc. At both applications rates, Aquaprene EC was extremely effective (99%) at significantly reducing adult emergence in the studies. Approximately one thousand 4th-stage larvae were added to each plot before treatment, and 24 h later pupae were collected to determine emergence inhibition. Aquaprene EC was applied at 7.18 and 9.57 g/acre. Efficacy studies were conducted with Aquaprene emulsifiable concentrate (EC) (33.6% active ingredient ) and wettable powder (WP) (40% AI) (S)-methoprene insect growth regulator formulations against larval Ochlerotatus taeniorhynchus in small field test plots.
