It is similar to the genus Icerya (Coccoidea: Monophlebidae), so it could be something related to it. I am not expert on Hemiptera (but Orthoptera), but I remember I've seen something similar to this in Croatia (not Icerya, but Coccoidea similar to Monophlebidae),
Yes, I agree, scale insect genus Icerya, frequent and invasive pest on different thermophilous woody plants. The ladybirds and other aphidophaga are among most important natural predators. Nice, but dangerous with its hermaphroditism also in glasshouses around the world.
These are mealybugs of mango and they are an important pest of mangoes in the Indian subcontinent. There are several species and pink mealy bugs are also common. Following is the technical bulletin from National Center for Integrated Pest Management of India on mealy bugs:
The pink hibiscus mealybug (Maconellicoccus hirsutus) in Mexico is an exotic pest, to which you think the copy is displayed. In Mexico I mention it damages plants mainly soursop, mango, yacas, carambolos, citrus, Jamaica, bean bean; ornamental as obelisks, Ixora, forest species such as teak, and wild plants parotas as "shells, huizaches, Jarretaderas, sierrillas, scribbles, among others." Of particular preference for "Majahua" (Hibiscus pernambucensis), where year-round is present.
It is the basis of the integrated management of the campaign; frees the predator Cryptolaemus montrouzieri when there is a high level of infestation (More than 20 HRC / outbreak of 5 cm.) and the release of the parasitoid Anagyrus kamali, low infestation level (less than 10 HRC / outbreak 5 cm). Released from 1,500 to 2,000 m Cryptolaemus. and 1500 to 2.000 Anagyrus k. per hectare, depending on the level of mealybug infestation.
Should be released in the morning or evening without the presence of showers
Yes, this is Icerya aegyptiaca, not Rastrococcus. They are very common in Bangladesh and the host plants are Guava, Mango, Jackfruit, and many other fruit & ornamental plants.

Dear colleague.
I noticed that your query received about five identifications. It is a scale insects (Hemiptera: Coccoidea). A reliable identification of this scale insect will be determined by a study of well-prepared slide-mounted specimens.
