It lays tiny eggs in small clusters on growing areas of the plant, such as flowers, shoots, and new leaf buds. These areas are the feeding spots for the larvae, which emerge after a few days and eat voraciously for two weeks. The younger larvae are thin white caterpillars with numerous small black spots.
In the adult form, it eats leaves of many crops, including squash, cucumbers, soybeans, cotton, beans, and corn. Adult beetles lay eggs in the soil near a cucurbit plant. In a lifetime, females can lay between 150-400 eggs. However, there have been cases in which females have surpassed this quota, with some laying a total of 1,200 eggs. [7]
Squash mosaic virus (SqMV) is a mosaic virus disease common in squash plants and other plants, including melons, of the family Cucurbitaceae. [1] It occurs worldwide. [1] It is transmitted primarily by beetles, including the leaf beetle (Acalymma trivittata), spotted cucumber beetle (Diabrotica undecimpunctata), [2] [3] and 28-spotted ladybird beetle (Henosepilachna vigintioctopunctata), [1 ...
Cucurbita female flower with pollinating squash bees. All species of Cucurbita have 20 pairs of chromosomes. [15] Many North and Central American species are visited by specialist pollinators in the apid tribe Eucerini, especially the genera Peponapis and Xenoglossa, and these squash bees can be crucial to the flowers producing fruit after ...
The name squash bee, also squash and gourd bee, is applied to two related genera of bees in the tribe Eucerini; Peponapis and Xenoglossa. Both genera are oligoleges (pollen specialists) on the plant genus Cucurbita and closely related plants, although they usually do not visit watermelon, cucumber, and melon plants. [ 1 ]
It is largely spread by the insect vector of the western flower thrips. The virus infects more than 648 species of plants including important horticultural and agricultural species such as fuchsia, tomato, orchids, [2] and lettuce (especially romaine). As the name implies, the main symptom on plants is necrotic spots that appear
Squash blossoms are highly perishable, and as such are rarely stocked in supermarkets. [2] Male and female squash blossoms can be used interchangeably, but picking only male flowers (leaving some for pollination) [3] allows the plant to also produce some fruit (squash). [2] [3]
Colletotrichum lindemuthianum is a fungus which causes anthracnose, or black spot disease, of the common bean plant (Phaseolus vulgaris).It is considered a hemibiotrophic pathogen because it spends part of its infection cycle as a biotroph, living off of the host but not harming it, and the other part as a necrotroph, killing and obtaining nutrients from the host tissues.
