“…Intramandibular secretory cells of class III in newly emerged virgin queens differed morphologically from those found in 7-day-old virgin queens, which were irregular in shape. This shrinking, which resulted in irregular gland cells, suggested that these gland cells suffered morphological age-related changes, but we did not find pyknotic nuclei, apoptotic bodies, or acid phosphatase in the cytoplasm, which were signs of advanced degenerative processes in insects (Armbruster et al 1986;Dimitriadis and Kastritsis 1985;Skelton and Bowen 1987;Jimenez and Gilliam 1990;Bowen 1997, 1998;Teixeira et al 2013).…”

The interactions of insect societies are associated with chemical signals released by the exocrine glands that control some insect behaviors. Exocrine glands can be classified into different classes: class I release substances that cross the body cuticle and class III glands that have a conducting canal. This study compares the morphology of intramandibular and mandibular glands in virgin queens of different ages, as well as in nurses and forager workers of Melipona scutellaris. We have found the occurrence of two types of glands inside the mandible; glands of class I, corresponding to a well-developed epithelium, secretory only in virgin queens, and glands of class III. On the other hand, mandibular glands have been found to be well-developed in workers and queens and they also have high amounts of mitochondria and smooth endoplasmic reticulum. Together, these data show that the mandibular and intramandibular glands of M. scutellaris virgin queens have morphological features that indicate the synthesis of compounds that are lipid in nature. Furthermore, both glands have a similar developmental degree in newly emerged and 7-day-old ones.

“…Acid phosphatase as a lysosome marker and free acid phosphatase activity have been determined histochemically in haemocytes and salivary glands [1], fat body [6] and salivary glands of metamorphosing Calliphora erythrocephala [3], in the midgut of Drosophila auraria larvae [7] and in the ventriculus of 5-and 30-day old adult worker honeybees, Apis mellifera [13]. Cytochemical analyses of acid phosphatase were also carried out during physiological cell death in the midgut of Calliphora vomitoria larvae [20], in developing Heliothis armigera midgut [5] and in the salivary glands of Drosophila melanogaster larvae [14].…”

Acid phosphatase activity in the midgut of honeybee (Apis mellifera L.) larvae

-Acid phosphatase activity has been used to characterise lytic activities within honeybee larvae midgut cells. Significant nascent or free acid phosphatase activity was found in the midgut of 2-, 3-, 3.5-and 5-day-old honeybee larvae. Free acid phosphatase in the cytosol of the midgut cells appeared to be a prelude to cellular autolysis. The source of free acid phosphatase activity was not lysosomal as there was no sign of acid phosphatase activity spreading or leaking from lysosomes. The fine structural localization of acid phosphatase in lysosomes and cytoplasm in honeybee larvae was compared with findings previously reported in other insects. © Inra/DIB/AGIB/Elsevier, Paris Apis mellifera / honeybee larvae / midgut / histochemistry / cytochemistry / acid phosphatase

“…The patterns of s- or m-ALP-specific activities were identified in the beetle midgut and were correlated with feeding activity of Colorado potato beetle, Leptinotarsa decemlineata ( Yi and Adams 2001 ). Several studies have also reported that mammal and insect ALPs were correlated to sucrose metabolism ( Crane 1960 ; Dimitriadis and Kastritsis 1985 ; Jimenez and Gilliam 1990 ; Yamamoto et al 1991 ). The B-biotype and T. vaporariorum are piercing-sucking insects with stylet-like mouthparts that are used to feed on the phloem sap, which mainly contains sucrose.…”

Bemisia tabaci (Gennadius) B-biotype and Trialeurodes vaporariorum (Westwood) (Hemiptera: Aleyrodidae) often coexist on greenhouse-grown vegetable crops in northern China. The recent spread of B. tabaci B-biotype has largely replaced T. vaporariorum, and B-biotype now overlaps with T. vaporariorum where common hosts occur in most invaded areas. The impact of the B-biotype on the agro eco system appears to be widespread, and involves the ability to compete with and perhaps replace other phytophages like T. vaporariorum. An emerging hypothesis is that the B-biotype is physiologically superior due at least in part to an improved ability to metabolically utilize the alkaline phosphatase pathway. To test this hypothesis, alkaline phosphatase activity was studied in the B-biotype and T. vaporariorum after feeding on a number of different hosts for a range of durations, with and without host switching. Alkaline phosphatase activity in T. vaporariorum was 1.45 to 2.53-fold higher than that of the B-biotype when fed on tomato for 4 and 24 h, or switched from tomato to cotton and cabbage for the same durations. However, alkaline phosphatase activity in the B-biotype was 1.40 to 3.35-fold higher than that of T. vaporariorum when the host switching time was ∼72 and ∼120 h on the same plant. Both short-term (4 h) and long-term (72 h) switching of plant hosts can significantly affect the alkaline phosphatase activity in the two species. After ∼120 h, feeding on tomato and cotton alkaline phosphatase activity in the B-biotype was significantly higher than that of T. vaporariorum. It was shown that alkaline phosphatase aids the species feeding on different plant species, and that the B-biotype is physiologically superior to T. vaporariorum in utilizing the enzyme compared to T. vaporariorum over longer periods of feeding.
